Rated 5 out of 5 by Texan42 from Will buy them again I have 22,000 miles on my STT PROs and they still look great! I off road many times a year when up at the ranch and they have never let me down....they get me through things that I wouldn't try with other mud tire brands....IMO THE BEST!
Rated 4 out of 5 by Heyyou from Great for plowing, now buying ST/MAXX After about 20 sets of M/T, I thought to try something different. Bought 4 STT pros. 295/75/17. After 6000 K. Never spun a wheel all winter plowing, Still look new! Quite ride considering tread , but with no plow on & only a 625lb. Salter in the bed, you can hear me coming a block away,well figure when I hook up my plow! Just ordered 305/70R 18 ST MAXX for the summer. 2018 3500 HD single wheel Duramax.
Rated 5 out of 5 by Lenny from These are the tires for all needs I bought some 295/65/20 (35 inch) tires for my lifted F150 and I can tell you these tires are simply awesome. I was expecting a much louder ride because of the aggressive tread, but I was pleasantly surprised when on the road and highway. These grip the road better than my other tires too, even in rain and icy conditions. I highly recommend these tires for anyone wanting a better tire for both off-road and around town.
Rated 5 out of 5 by Dave65 from Great tires Have 40,000 miles on a set of 275/70/18's on a 2014 Toyota Tundra. These tries will likely last another 5,000 miles (they have about 4-5/32's tread left) through the summer. Wear even, great off road performance on Wyoming backcountry 2 tracks in mud or snow. Sidewalls amazing for no rock/stump damage. Will be buying another set. Fairly quiet on highway for how aggressive they are, last 5,000 miles or so the "road noise" has definitely increased.
Rated 4 out of 5 by Truck05 from All around tire Dont ever write on deals like this but figured might try once. The stt pro is an excellent all around tire for people who drive all conditions and are have a broad spectrum of uses and not bent on singular scenario preformance. I cannot comment on mileage becuase of driving conditions but it was north of 30,000 miles. My driving is hwy all conditions and off road also, I have always gotten traction when needed and handled good with loaded gooseneck cow trlr. The tires are what they are ment to be and I have no bad ratings or comments with that said I am not purchasing these becuase of my vehicle use but I am going with the st maxx. I have researched quite a bit on the at3 Lt and was torn between the those 2 styles but I still believe 4wd truck used off road needs to have tires suited for that environment and I dont need an aggressive tire as I used too and would like to get more mileage from my purchase if possible. My fuel economy was still normal. I'm happy with the cooper brand!
Rated 2 out of 5 by Grandsportim from Good off road, bad on road I had the cooper st Maxx before and loved them. Switched to thses st pro's in the same exact size. I instantly lost 5 mpg. The trick is a 2013 F150 Ecoboost. Tried playing with tire pressure and no matter what I do the truck gets 13mpg when it used to get 18+. I've had them on for about 15k miles and they have gotten pretty noisey too despite rotating every 4k miles. Tires still have a ton of tread left but now I'm looking to purchase a different set. I just can't get over the mpg drop and the road noise.
Rated 5 out of 5 by Asmodeus from Off road tires without a compromise These tires are awesome. I've put about 5,000 miles on by now, through every type of terrain and weather. Mounted them during a snowy winter, and I've been mudding hard since the snow melted and the rain began. These things are absolute beasts off road, and surprisingly good in snow and on pavement as well. There is barely any noise despite the aggressive tread, and no noticeable wear in 5k miles. No damage from the rocks so far either. I should also mention that I am a very aggressive driver. Highly recommend.
Rated 5 out of 5 by 89grand from Smooth and quiet tire considering how aggressive it is. I recently had these installed on my 2000 Wrangler TJ in 33x12.5x15. They have a slight hum on the highway, but it is far less than expected for an aggressive looking mud tire. They are quite smooth riding on the highway at 65-70mph as well. If anyone wants a dead silent tire get a mall crawler AT. Oh yeah, and these look cool to boot.
