Cooper Discoverer STT PRO 

I had a set of (5) 37/11.5/R17's on my 2018 Jeep Wrangler JL Unlimited Rubicon for 45,000+ miles (all 5 rotated every 10,000 miles) in every terrain South Louisiana can through at them. I also made a 3000 mile trip to Gatlinburg, TN to Buffalo, NY then back to New Orleans, LA in 5 days and they preformed flawlessly. These tires are amazing! Quietest road noise of any mud tire out there! They handle exceptional on road in daily driving, my 21 mile (one way) trip to and from work on highway was a Brees. The city roads and even the extreme pot holes on the streets of downtown New Orleans felt non-existent. The Off Road traction and capabilities of these tires are outstanding! Rock crawling mixed with wet mud on a 45 deg. incline...didn't even break traction with them aired down to 15psi. You want a tire that will give you (in my opinion) the best multi purpose use daily...Look no further!

NOTE: This was my first ever set of mud tires, didn't really expect to get 45,000 miles. I really should have rotated them much more often...I started to get some vibration in the front end around 35,000 miles. Now, part of this was do to not having adjustable track bars front and rear of my Jeep when I installed the 2" Mopar lift causing ware and tare. The other part was the tire rotation intervals...had I done them every 3,000 miles, I would have prolonged the life of the tires to 60,000 mile easily and prevented some of the ware and tare on the steering components. The uneven ware caused by the lack of rotations made the vibrations and noise in the tires to much.

First of all fast service , #1 in my book, the tires are the best i have ever owned. I plow snow and live on a dirt road. I never have traction issues . I would recommend these tires to anyone that wants the confidence to get where they are going!!!! I'm willing to take a little road noise for great traction.

I really like the tires i use them for going through deep snow. i run them at 15 to 10ish PSI i have had really good luck with them would recommend them if you go through deep snow. even at low PSI i haven't had them de-bead.

My second set of the SST Pro's and still am very impressed with the ride comfort, handling in all terrain types, and longevity. Noise is a little loud but that's expected with such an aggressive tire. Constantly get complements on how they look. I got about 55k on my first set. I've driven over snow covered donner summit and never had any trouble with traction. They're on the expensive side but definitely worth the investment.

Awesome tire I’ve only driven 150 miles on them. The traction is unbelievable for rocks, mud, dirt and deep snow I would definitely recommend these tires for someone who’s looking for a great off road tire.

This would be my second set of STT PROS. The first set was on my Ram 2500. These tires are not for the person looking for a smooth and quiet ride. I have had no balancing issues with these tires. They look amazing on my truck in my opinion. They are awesome offroad and in the mud. Even when not in 4wd. Really good in the snow. Noisy.......but not mud grappler noisy. I think the good out weighs the bad here. Besides the noise I love these tires but feel they are more at home on an HD truck. My 2 cents. Thanks for reading.

The Best tires I have ever had in my life! Cooper Discoverer STT PRO 315/75R-16 is the only tire I will put on a T-100 4x4 truck or my 4x4 Ford Off-road Adventure RV same size. It has been a life saver in the Extreme ice storm to driving in Deep Sand in the summer to look at property's. I drive from Oregon to Arizona and I will not buy any other tire for my OffRoading to Highway Life. My STT's have been rotated on every oil change on both rigs and they still look new. Thank you Cooper Tire for outstanding new tire technology.

Great tire! Noisy, but should be expected with the large mud block design. Much louder when cornering at speed. Absorbs road bumps much better than stock tire did (Goodyear) and feels more stable. Would definitely buy again.

Excellent off road tire for warm climates. Very durable and almost no damage to any of the tread blocks after 15,000 miles. Not as noisy as I expected and on road manners were as expected, good but not great. Tread wear was less than expected, less than 20,000 miles to burn up a set on a 2500 Cummins. Rotate every 5,000 miles or you will get bad cupping on the front. My truck recommended tire pressure is 80 rear and 60 front. Cooper recommended these at 70 rear and 50 front. 55 rear and 45 front seemed to work best for me, less cupping in the front and smoother ride overall. Terrible ice and snow tire. The truck would not move in 2 wheel drive with any amount of hard pack or powder snow. Bought snow tires immediately after the first snow. I did some towing with these tires, nothing more than 10,000 lbs, and they did well, stable and responsive. The looks are amazing and the tracks left behind in soft ground are cool to look at, but don't buy these if you live in snow country. Utah, Arizona, Texas, New Mexico, Georgia, Alabama, or any place really where it does not snow, these tires would be great.

This tire is great. Everything it promised to be. Good looking, long tread wear, puncher resistant. The only thing I can think off as a negative is they are noisy and need to be rotated as required. I will buy them again and again.

Tires looks are second to none! Best looking tire for a truck period. Tire is used for mainly daily driving with the idea of weekend warrior and some. For a daily driver, it's not a bad at all for an off-road tire. I'd say the biggest sacrifice you need to consider when purchasing this tire is how much do you value quite ride and comfort? Highly recommended running what the vehicle manufacture tire pressure specs are in these tires. Place I had install the tires recommended me to run these at 55psi . After a year i decided to put it back to 32psi and what a difference!! I have put about 45,000 on these bad boys and i still have 10.5/32 of tread left. If you like compliments buy these tires!!

I've had Goodyear wrangler and bfg t/a ko2 tires. These cooper stt pro tires are far superior. I drive about 10 miles a day on unimproved and un maintained roads and another 10 miles a day on highway. These maximum traction tires are superior to those other 2 "all terrains" . These have good treadlife no chunking of tread like the others. And the traction actually will take you on all terrains.
