I have purchased 4 sets of these tires over the past 5 years. When you drive 45,000+ miles a year, you definitely want the best quality and bang for the buck. These tires deliver. My last set had 88,000 miles on them and had at least another 25000 miles before hitting the wear blocks! Well worth the money! Just be sure to rotate every 5K-6K miles.

These were great tires! Looked awesome, handled well, gripped well, etc. Then they started leaking air within 15k. Subsequently, tread started to wear. Still, solid tires, ran great, couldn't complain otherwise. Then, within maybe 5k of each other (at about 40k), two tires both blew -- major, unpatchable failures with broken cords. Strong start, disappointing finish. Since then, I've talked to two friends who have had the same issues with the lighter-grade tires. However, a friend who put 10-plys on his F-450 still loves the tires and has had no trouble whatsoever. Hence a thoroughly mixed review -- love the performance to a point, and 2/5 stars for if I would buy them again. Even as I sit debating which tires my truck should be shod with next, the Discoverers still look good -- waiting for the second chance...

Some of the stars above I cannot technically comment on, but was afraid by not doing so would detract for the score on the tire. Today, in snow, the AT3s impressed me. The OEM Continental Contitrac tires on my SuperDuty got me stuck on wet grass, mud, and even the thought of a light snowfall. I was so disgusted with the Contitracs that I thought about going extreme, getting STT's - but I just couldn't afford them. My dealer had a deal going on AT3s and I thought the value was too good not to try. Today was the test. About 3 inches of cold snow on the ground, some bladed into 8-9" humps around my driveway. My SotF 4wd wouldn't engage while trying to pull my 20' livestock trailer. I needed to back it into a spot. These tires never slipped in 2wd, even over the humps of piled snow. I have SRWs and was a little worried about carrying capacity. I've hauled a 17,000 lb tractor with a 10,000 lb tandem gooseneck and my SRWs handled it wonderfully, even with having air pressure issues due to the installation of passenger car tire valvestems (all rubber - since corrected). The tires have me very impressed.

I just replaced the only Goodyear tires (Wrangler Silent Armors) I've ever liked on my Jeep. I got 80,000 perfect miles out of them. I would have bought another set, but they have become outrageous in price. I researched the heck out of a decent 30/9.5/15 replacement and found that for the wrangler, this is a tire of choice amongst the forum groups...mine happens to be bone-stock. I left the dealer with a brand new inch of wet sleet and 22 degrees. I was traveling 50 mph when I realized, that I wasn't in 4WD. All I can say is wow...if that was the first impression of what to expect, then I'm sold on these. I noticed significantly more steering feedback right off the bat and have since run 70+mph down my usual two lane. I'm not exaggerating here...these tires are 50% quieter than the wranglers. I'll leave periodic updates moving forward. I rotate every 5,000 so we'll keep updating incrementally.

I researched many different all-terrain tires and even cruised parking lots taking my own survey from the owners about how they liked their tires. After having these installed I've driven in more snow than ever before in my life - up to 16" on our private road which doesn't get plowed regularly. These tires will not spin at all unless you're on glare ice. During a storm I can pull over into an unplowed lot with over 12" of snow, get out to clear the ice from my wipers and start right up without spinning, driving through 20" plus snow piles to get back on the roadway. BUY THESE IF YOU WANT GOOD SNOW TRACTION!! They're also very quiet on bare pavement at highway speeds. I could not be happier with these tires!!

Great tires! I drive over 100 miles a day with my job and on multiple occasions in snow, sleet, heavy rain, and these tires always handle great. I was able to get a little over 50k out of my first set and currently have 37k on my second set and they still have really good tread. Whenever these wear down, I will put a third set on. Great tires, great quality, great product.

Excellent dry and wet traction. The cornering stability/steering response is much better then what came on the truck from the factory. Snow traction is good for not being a snow tire. So far I am very impressed with the amount of miles I have on the tires and how much they have worn. I will be buying these again for my next set of truck tires.

These are actually on a 2000 Silverado z71ext cab. Very great tires, handle mud, snow, rain, everything. I've had them on the truck for 5 years and 88k miles later it's finally time for some new ones. And yes this is what will be going back on it. I have no complaints on these. I've seen people complain about road noise but these do not have much road noise. If you think it's too much you should probably buy a car. Best all terrain tire out there.

I placed these tires on my truck which gets a wide variety of use. I have placed a 2.5" leveling kit on the front end, which raises the center of gravity a bit. I do a moderate amount of highway and city driving, a fair amount of towing a 32' camper, a 15,000# work trailer and random in-bed work loads. Overall, these tires preformed better then expected. They far out performed other "Brand" tires in the same class. My tires are inflated to 70 p.s.i. which does great at heavy loads and towing! This pressure/tire combination makes city driving a little bumpy, but then again I drive a big truck. Snow, mud, and off-road traction is pleasantly surprising. I have had these tires in the dirt and snow more than once and they have yet to let me down! Side wall 'play' is noticeable, but I feel it is well within normal ranges based on the size of the tire and my specific application. I would recommend these tires for anyone looking for a "all round", all-season tire!
