3 SimpleTire reviews

Only have had them on for about 1500 miles. I put them on my 2008 f250 gas. So far I really like them. If they keep doing well, I will be putting them on my 2012 f350 diesel. Alot quieter than I thought they would be, ride it good for a 10 ply.

• Miles driven on tires 5k - 9k

As with any all-terrain tire there was a little bit of loss in the softness of the ride, and a slight humming noise. But beyond that I was very impressed with how quiet these tires actually are for how aggressive they actually look. I chalk some of that up to this being on a 22 inch rim and a lower profile all-terrain tire. For the price and the look and the comfort of this tire I would recommend it to anybody who does more street travel then off-road. I never knew Cooper made such a great tire!

• Would you buy again? Yes
• Miles driven on tires 10k - 14k

Replaced my Bridgestone Dueler "A/T" with these tires on my 2018 GMC Sierra Denali. Love the way they look over the stock tires. Biggest thing that surprised me was how quiet they were for how aggressive the tread pattern is. Barely any noticeable difference at all. I put about 2,000 miles, mostly interstate on these tires in the first 6 weeks. No significant road noise all the way up to 90mph. They handle great on dry roads, no issues on wet roads either but I haven't driven through any really heavy rain. Only downside I have at all is fuel economy. I was getting an average of just under 20mpg with my old tires and after 2500 miles i've averaged 18mpg with these. Overall, would definitely recommend.

Cooper discoverer rugged trek – first look and initial impressions.

Cooper Discoverer Rugged Trek (285/70/17) – On-Road & Off-Road Initial Impressions on the 5th Gen 4runner

A relatively newer tire from Cooper (released in early 2021), the Cooper Discoverer Rugged Trek walks the line between an All-Terrain and a Mud Terrain, being loosely classified as a “hybrid” tire.

I knew this when I ordered them, but was admittedly shocked by the amount of tread/overall beefiness of the tires when they arrived. Featuring two sidewall options, they provide a small style choice to accompany their rugged look. The tires mounted extremely easily and took to road force balancing pretty well.

Two out of four tires balanced almost perfectly, leaving the other two needing a bit more attention, but I attribute a lot of this to my stock Toyota wheels which have a history of being difficult to balance.

My Tire History 

These tires are mounted on a 2016 Trail Premium, with a Dobinson’s 2″ suspension, Spidertrax Spacers, and the factory Trail wheels. This setup required a body mount chop and a decent amount of trimming to the fenders/wheel wells . On this 4runner I have had the following tires for comparison:

• Dunlop AT20 – 265/70/17
• BFG KO2 (C load) – 265/70/17
• Falken Wildpeak (SL load) – 265/70/17

Why I Chose the Cooper Discoverer Rugged Treks

After installing a 2″ Dobinson’s suspension, I had a great excuse to bump up to a larger tire. Personally, 285s fit the bill for me of maintaining visual proportions, adding a bit of height/width, but keeping things practical for a daily driver. The two obvious (and popular) choices were BFG KO2s and Falken Wildpeaks. Personally, I did not like the wet traction of the KO2s when I had them, so they were out, leaving the Falken Wildpeaks as the other choice.

The Falken’s have been great, everything about them, and I have zero complaints, but I also wanted to try something new, which led to a long excel spreadsheet and countless back and forth moments of tire comparison.

Ultimately I landed on the Rugged Treks due to the sweet spot they fell in as it relates to weight, cost, performance rating, and of course looks. Not to mention, I have had Cooper’s (ATP/AT3 lineup) in the past on a 3rd generation 4runner and knew their quality and longevity.

On-Road Performance: Dry Conditions (8/10)

I have only had these tires installed for about 800 miles, so this is a very early overview, but so far I am impressed with these tires.

Ride Comfort

Because I made a lot of changes at once (most notably, suspension), it is hard to assess a 1:1 comfort rating. I went from a stock size SL (31.56″) to a larger E load (33.03″), so things obviously felt different on the road, but all in all, I am very impressed with the overall comfort from such a large, aggressive tire. At commuting speeds (below 45mph), they feel amazing. Smooth, grippy, and controlled are all words I would use to describe them.

Reaching interstate speeds (70mph-80mph), this still rings true, but you “feel” the road more. The lugs follow the grooves in the pavement a bit and the inconsistencies in the road are carried through the stiffer rubber into the steering wheel. For anyone with larger, heavier ply tires, this is all probably common, but it was an initial shock from a stock SL size.

If you believe in the accurate scientific properties of a decibel meter app for your phone, then I can tell you that these tires are actually several decibels quieter than my stock size Falken’s with ~50% tread. That’s hard science there, a 285/70 with 18/32″ tread is quieter a 265/70 with 7/32″ tread, at interstate speeds. I was pleasantly surprised. Audibly I heard nothing more than the typical AT hum.

On-Road Performance: Wet Conditions (7/10)

When I had KO2’s I noticed slipping in wet conditions almost immediately after installing them, on a hill, on a flat turn, etc. I could easily get the tires to break loose. I was excited to try these in the same conditions. I can’t get them to break loose.

Cooper has done a great job with their siping to expel the water from between the treads. These tires seem very planted on wet pavement, from slow speeds all the way up to interstate speeds. Obviously, they’re an AT, not a dedicated road tire, so they incur a little hydroplaning, but nothing that seems unsafe.

Off-Road Performance: Dirt / Gravel / Rock and Aired Down (9/10)

Aired down to about 20psi, these tires stuck to the gravel forest service roads like it was pavement. I also had the opportunity to pull a small trailer as well and they performed flawlessly, there was no wondering or harshness to the ride, the tires felt planted and in control. Leaving the gravel and engaging 4×4, these tires continued to shine.

The tire conformed nicely to the rocks and the aggressive sidewalls kept them from just sliding off of anything they touched. They handled small to medium size rocks and roots, uneven terrain, and loose dirt with ease. My testing was limited, but for the short amount of time I’ve been running them, these tires have been impressive.

Off-Road Performance: Mud (6/10)

This isn’t a dedicated Mud Terrain tire, but I was able to test them a little in the two types of North Carolina mud we have; slimy, stinky brown mud, and slick peanut butter clay. In the former they preformed well. They were able to gain and maintain traction, and the lugs cleared extremely well. In the latter, it was like driving on an ice rink.

Although I didn’t have a great testing ground, and didn’t have a Mud Terrain to compare to, I do feel that the increase in tread depth and space between lugs help these tires to perform better in mud than a traditional AT tire. If I were to be driving in a lot of mud often, I would look to a MT, but for the performance, and the benefits gained in other ways, this fits my needs perfectly.

Before and After

Before – 265/70/17 Falken Wildpeak on stock suspension

After – 285/70/17 Cooper Discoverer Rugged Trek on Dobinsons Suspension

Previously I thought the Falken Wildpeaks had an aggressive tread and looked pretty beefy, but after looking at the Rugged Trek’s, there is no comparison. Obviously, the increase to 285’s helps, but these tires look good!

Final Thoughts

Albeit an initial impressions review, so far I have nothing but good things to say about these tires. If you acknowledge the repercussions that come with an E-rated tire weighing 58 pounds, then all the rest is positive from me. Out of the multitude of tires that were on my list, I am happy that I settled on these and finally committed. I hope to see more of these on 4runners in the future; if for no other reason than to break of the sea of Wildpeaks and KO2s.

Would I recommend them?

Absolutely. I would recommend these tires to anyone looking to run an aggressive AT without wanting to commit to an MT. They nicely fit the bill between the two and behave well on road for a daily driver as well. Time will tell on longevity, but if they are anything like the Coopers I have had in the past, this will be a tire I keep coming back to.

Mitch, I appreciate the review. I have been a die hard Toyo AT III guy. Just moved from a diesel Porsche Cayenne to a Ford Expedition… I know seems odd, but needed more room as a work vehicle. I have been going back and forth between the Toyos and the Coopers and then a friend swore by the Falkens. So mental gymnastics on my part. I think, I am ready for change in the only part of the vehicle that touches the ground. You gave me the nudge that I needed to go with the Coopers. Once I get them, I will report back.

Now that some time has past, has your view of this tire changed? I love the look of the tire and the fact it has a mileage warranty. I want to put them on my Silverado z71. Thanks for your info.

I’m now at 30k miles and my review has not changed at all. I still love them and they’ve performed well in all situations and the wear/noise has been great.

i wonder how the 6 ply version would ride? Thinking about these for my wife’s 4runner. We are about to put a 3” RC lift on it, going to Colorado next summer and I wonder if the 6 ply will hold up to 1 week worth of dirt trail driving around the alpine loop

Nice review, these look great! How does the wet performance compare to the Falken Wildpeak AT3W?

I would say it’s the same. I haven’t noticed any slipping, and I’ve tried. There is obviously more spacing between the lugs, so you feel it a little more in standing water, but nothing that feels unsafe.

Hello Mitch,

Great blog! I’m looking to get these in stock size, but they have two options I’m torn between. They have a 265/70r17XL (31.89 dia) and the LT265/70r17/10 (32.01). Do you see an issue running the XL instead of the LT? Would I need to still get a BMC with either option? I’ve provide a link below:

https://www.tirebuyer.com/tires/cooper/discoverer-rugged-trek/p/TV090088330

I’m in the same situation trying to decide between the xl and lt, I have a stock limited switching to 17 inch rims, 265/70/17.

Also forgot to mention, I’m still on stock suspension.

Hi Mitch – great article!

I’m doing a mild offroad / overlanding build of my 5th Gen. Currently have about 400lbs added for a Gobi rack, sliders, skid plate and some other stuff, and planning on completing this stage of the build with Dobinson IMS suspension for 2.0-2.5″ lift, RRW 17×8.5 RR5-V wheels, and (hopefully) 285/70/17 (33”) tires – likely KO2s or Coopers.

Your setup seems similar, and you wrote that you needed extensive trimming and a BMC. Various other articles suggest no need for trimming/BMC with AT 33”.

Any more info on your experience would be incredibly appreciated. Thanks!

I know I responded to you via email, but I wanted to give a brief response here for others benefit:

Trimming / fitment / rubbing has a lot to do with wheel offset, exact tire, alignment, and general use (off-roading vs road driving). Generally speaking you will at least need to trim your front bumper / inside wheel well to fit 33s, but a BMC is dependent on the above factors mentioned, primarily wheel offset. The further your wheels / tires sit outside the wheel well (negative offset), the greater your turn arc and higher potential to rub places.

With the above in mind, I took the safe route and had a BMC, but after having it done, and running 1.25″ spacers, I 100% would have rubbed without a BMC and front fender trimming.

Cooper Discover Rugged Trek Reviews

Check out our reviews if you’re seeking for all-season truck and SUV tires built for adventure!

The Rugged Trek, released in early 2021 from Cooper , is a cross between a mud-terrain tire and an all-terrain tire.

This is an all-season tire for trucks and SUVs designed for off-roading adventures while also providing exceptional performance on the highway for regular usage. A 60000-mile guarantee comes included on the tire.

The product also gives drivers the option of choosing between two distinct top designs for the sidewalls, one on each tire side, for a distinctive look. Off-road traction is updated with long, deep cleats on both sides, along with black raised writing in all sizes.

Pros & Cons

• Off-road prowess is incredible.
• Highway travel is pleasant and calm.
• Mud tire with a combative look
• Reliable treadwear with long warranty
• They are an AT, not a dedicated road tire

Personal Thoughts

If you think that a decibel meter app on your phone can accurately measure scientific qualities, then we can tell you that these tires are many decibels quieter than stock size Falkens with 50% wear. 

At interstate speeds, a 285/70 with an 18/32′′ tread is quieter than a 265/70 with a 7/32′′ tread. It was a great surprise for customers. We couldn’t hear anything but the standard AT hum.

Wet Conditions

Cooper did an excellent job of removing water from between the treads with their siping. These tires appear to be quite well-anchored on wet pavement from mild speeds to interstate speeds. 

Because they’re an AT and not a specialized road tire, they hydroplane a little, but not to the point of being dangerous.

Performance On Dirt, Gravel, And Rock 

These tires adhered to the gravel forest service roads like concrete after they were down to around 20 psi. The strong sidewalls protected the tire from slipping off of whatever it came into contact with.

Small to medium-sized pebbles and roots, uneven terrain, and loose dirt were no problem for them.

Mud Terrain

Although this is not a designated Mud Terrain tire, they could get and keep traction, and the lugs were cleaned effectively. It was like driving on an ice rink in the latter case.

The increased tread depth and space between lugs help these tires perform better in mud than a conventional AT tire. If we were going to be driving in a lot of mud regularly, we would go for an MT, but this is ideal for the performance and other advantages.

A Closer Examine

The Discoverer Rugged Trek has an all-season tread pattern with huge shoulder scoops that scrape out dirt, sand, and mud, letting you easily navigate soft terrain. 

Stable TracTM Technology improves traction and handling in difficult conditions while jutting ridges evacuate stuck stones and protect against harm from sharp pebbles. 

This durable tire also has dual sidewall designs and class-leading tread depths (16/32″ for SUV sizes; 18.5/32″ for LT). Finally, specifically built sound barrier walls minimize road-noise, resulting in a more pleasant on-road driving experience.

Who Should Buy This Tire?

We can see the Discoverer Rugged Trek as an aggressive All-Terrain tire that incorporates the company’s newest technology. 

The shifted shoulder block contains the Earth Diggers Technology, allowing it to grip better in the deep mud, dirt, or sand and increase traction when traveling off-road. This item is the ideal tire if you want to conquer on- and off-road terrain, thanks to its aggressive and robust appearance. We hope that our reviews will assist you in making an educated selection!

Discoverer Rugged Trek Ratings By Consumer

Based on 04 rating(s)

Recommended by 03 driver(s)

By 04 driver(s)

If you’re looking for a tire that can handle some tough terrain, these tires will do the job as they offer reliable traction and minimal slippage when conditions get muddy. However, despite having only 300 miles so far on them, it is worth noting their somewhat higher noise levels compared to other brands with an equal treadwear – although this should be kept in check by ‘whisper grooves’. In any case those seeking rugged off-road tyres may find these favourable but if most of your driving time involves plenty of highway journeys then its best to look elsewhere!

Over the years, I have been both a tire seller and driver. With 11,500 miles under its belt atop Cooper’s Whisper Grooves tires, my truck has proved itself to be an exceptional ride with excellent tread wear measurement of 12/32 at this mark -16/32 when new. Rotations are recommended every 3-5 thousand miles as shallower all terrain tires can slow down wear in comparison to deep-tread ones where the first few 32nds tend to experience more strain over time.

Cooper tires have created the perfect tire for anyone wanting a fierce-looking tyre without sacrificing ride comfort or noise. Beneficial features such as no shoulder cupping, perfectly balanced tyres and superior wet traction add to its excellence; making it an A grade on snow grip. With longer rotation intervals possible due to these benefits, highway motorists can look forward hitting the jackpot with Cooper’s aggressive pick up!

I’ve been thoroughly impressed with these tires in all weather conditions. Despite the aggressive tread pattern, they remain relatively quiet thanks to their 20″ stock wheels which are incredibly stable and robust enough for my F250 even when under a 2,400lbs fifth wheel trailer. After 5k miles of use I anticipate being able to get 40k out of them – no rubbing or side flex at full lock either! These have been great tires so far and highly deserving of another go around from me whenever it’s time for new ones.

I had been so excited to try out these tires on my 2021 Chevy Colorado ZR2, having experienced mixed luck with Coopers in the past. After 10k miles of frequent rotation at Discount Tire however, I’ve noticed that they are far louder than a worn set of Cooper STT’s would be and have suffered from cupping – much to everyone’s surprise!

Despite running them at 35 psi as advised for an XL tire not classified as E-rated, I’m sadly disappointed by their cost vs performance ratio and recommend looking into Goodyear or BFG tires instead – known brands that tend to last longer before issues arise.

With an aggressive tread pattern and great traction in deep snow, these tires got you through any slippery roads with ease. However, after 10k miles of use they have shown signs of wearing down – noticeable cupping and loud noise levels that went from a 4 to above 10+.

Product description.

The Cooper Discoverer Rugged Trek All-Season 35X12.50R17LT 121Q Tire is an all-season pickup truck and SUV tire that looks tough because it is tough. It looks aggressive but it also has nice manners. The Rugged Trek has a unique Rough Terrain pattern, which is trail capable and provides extra grip and confidence when you venture off the highway. It also features Stone Blockades, which are ridges in the tire pattern to help keep pesky stones and rocks out of the tire and on the ground where they belong, helping protect the tire from damage when you’re off the beaten path. Rugged Trek is built to provide enhanced grip on wet roads and features Whisper Grooves Technology that blocks the rush of air through the tire, helping to eliminate noise when on the highway. There are dual sidewall designs so you can pick between the Mountain Pass pattern or Knife-Edge pattern, which gives you double the options for your look. Our aggressive tread blocks are designed for quiet on-road performance and deep treads help grip in sticky mud and sand. While this is a tough-looking tire, it is also engineered for a quiet and comfortable drive.
