Tires Ride great my truck feels like a car now

These are really great tires, great traction, they wear great, they will make your vehicle stand out from the rest. They are a bit pricey. You get what you pay for though. They are a bit noisy on the highway, but the benefits out way a little noise. I recommend these tires 100%.

Okay so let me start out pointing out why this review needs to be taken with a grain of salt. I'm driving a 2015 Toyota Tacoma DCSB with a Manual Transmission. So any wet traction issues I'm having may or may NOT apply to you. I have only the spare tire, the Tailgate, and about 25ft of medium duty chain (average tow chain thickness) in the bed of the truck. I have skidplates, a front plate bumper, and rock sliders on my truck. Rear bumper is the stock tin one that for whatever reason they thought chrome was a good choice. So I notice these tires break loose much much easier than my old Mickey Thompson MTZs did. These tires are more on the line of Goodyears Duratraks after they've been ran for a year (Those were my tire BEFORE the Mickey Thompson's). I CAN bring the truck sideways with these things with no effort in the rain, and moderate effort dry. During the rain the TC comes on quite often on city streets. Dry weather these do amazing, they have been worn down quite a bit but stuck to the road like a sports car. Splashed through a puddle and they slid out but once they dried they were glued I could take turns and not even hear them whine about the g's. They have impressed me enough to bump up the rating to 4* but I wouldn't buy them again still I'm going back to my mickey's. I have taken them offroad and they performed better than I expected after how they did on the streets. I was able to crawl through 3 ft deep carved out mud holes and keep chugging along (provided I didn't get high centered like in the last hole, for those out of the loop high centered is your on your frame so your tires aren't doing you much good. My skidplate became more of a plow than a skid) I don't have more than 8k miles on the tires so wear is okay. I am noticing some chop but thats alignment issue not the tire itself. My neighbor has a Toyota 4Runner with this same tire. He has had the TCS come on quite a few times in wet conditions as well so be ware if you need to make a left at a light in the rain. Finally got some snow to test these in. They did GREAT. Went through about 5" of snow with no issue what so ever. Still able to have fun in a very controlled way. With the Mickey Thompsons the same price ±$5 I'd say save yourself the cons of these tires and get the mickey thompson Baja MTZs. Performance: DRY - 7 out of 10 WET - 3 out of 10 SNOW - 6 out of 10 MUD - 8 out of 10

I have 2 jeeps, and have had coopers for about 5 years now. My first big tires were Goodyear Kevlar - and they didn't last too long. Then I tried Nitto Ridge Grapplers and they allowed me to use my winch while the rigs on Coopers drove past me, so I changed to the SST Pro. Love them. Got a solid 40,000 out of a set of 40's, beating on them every weekend. On my wife's 2-door, she is up to 52,000 miles with about 3/16" of tread left. Last year, the pandemic forced me to get Mickey Thompson's for my 4 door, and so far they are working as well as the cooper. I hope they continue. When nobody around here could get them, I was able to Amazon a set for my wife, and she will be safe all winter.

Arrived quickly. Tried them out with NO balancing on them just out of curiosity, and they where pretty smooth. Offroad traction on trails has been great and these have taken the mildly modded Samurai to yet another level of improved capability. Previous tires were 10+ year old BFG AT with only 30% or so tread left and to be fair, I got them 2nd hand and didn't get to experience them new. So, probably any half way decent tire would have been noticeably better than old dried out tires, not matter how good they may have been when new. That being said, the Samurai nearly doubled it's abilities with it's 3" lift and move up to 31's... then adding a rear locker and proper diff gearing netted almost as big a gain again. Finally, adding these tires was not quite as big a jump as the other mods... but, again, a VERY noticeable gain in offroad traction and climbing ability. Long, 100% grade climbs that used to take effort and both hands and were a bit of a challenge, suddenly became casual, one hand on the wheel affairs. No chance to try them in in rain or snow yet.... but trail and rocky stuff has been great. Watch the "cooper puncture test" video online. As for noise.... my 4x4 is NOT my daily driver... so "tire noise" is more like TIRE MUSIC to me. But they are not particularly loud. Yes, you can hear them and they are more noise than your street car.... but, by FAR are NOT that noisy for mud tires. Prices on these fluctuate FAR more than BFG KM2 (my other choice).... but the BFG's would NEVER drop as low priced as these have from time to time.... When they dropped to only about $25 more than the cheapest tires out there, it was a no brainer! VERY pleased with them! [O.|||||.O]

I found 2 new ones for 100 on feebay and had to buy them, but these are about 3/4" taller then normal tires of the same size, so I had to pay full price for 2 more on my dually. When I installed them I was amazed at the traction but I noticed awful body roll feeling going around corners fast, like the tires were folding. Then I went on a trip towing a 35' cargo trailer and it was awful. The truck felt like it was all over the road swaying like I had no tongue weight, but I've pulled this trailer 100 of times. Recommend psi for the rears is 60 on my truck, even though it was a light load of less then 10k, I pumped em up to 80 psi and it made just a slight improvement in handling. So disappointed in these EXPENSIVE tires. I wasted 600 bucks on the two I got retail, and another 100 on the deal on feebay.

I purchased the 40x13.5r17 for my 76 Chevy 1 Ton. Mounted them myself on 17x9 Pro Comp Steelies with spoons and balanced with 13oz of balancing beads per tire. So far I’ve only put about 100 miles on them varying speeds up to 85mph and I’m more than pleased (aside from the price but they are massive tires and rubber isn’t cheap). They are smooth as butter and grip hard as heck. If I have any issues I’ll update!
