Best tire Ive ever owned. And Ive owned ALOT.
So far they are fantastic. Ordered them in 265/75r16s and got exactly what I wanted. There is some road noise from them, but they are by far the quietest M/T I've ever had. I dont know why some site list these as a mud tire and some list them as all terrains, but let me clear the air. These are a mud tire that also perform well on the road. I've had them on dry pavement, wet pavement, 16in snow, deep mud, uphill climbs, and on rocks. Excellent performance on all around. The only think I really havn't tried yet is sand. In my opinion these are the best tires Cooper has ever came out with.

If you’re looking for an aggressive looking & top notch off-road tire, look no further.
Love ‘em! I’ve had these on for about a year & a half, and have rotated them once. Completely even tread wear. They look spectacular with my black rims, very aggressive & rugged looking tire. I’ve had a ton of compliments since putting them on. I had been thinking about going with BF Goodrich or Nittos originally, SO glad I went with these instead. Great on the beach, in snow, and mud. Awesome tire, for a great price.

Good Looking, Quieter than expected
So I ended up with a skinny pair of these 215 85r16. They came with this weird manual transmission swapped Caprice Station Wagon that I bought. The guy who built the car would use it to tow a dump trailer full of hay in his field. Car has an elocker whole 9. I bought it to tow but didn't really plan to take it offroad. So I had a nice pair of mud tires. I also have a 2000 Nissan Frontier 4x4 that was on bald Bridgestones, I decided to mount them on some Xterra wheels and bought a second pair for my Frontier. They look good. a little small, plenty of clearance, but I dig em. They ride good, grip good, what else can you ask for? I think these work out to a 30.4" or so. They rose the truck up a good bit. Will have to get this thing offroad asap

Cooper Quality
3rd set of these tires on my Toyota and I can't say enough good things about them. The last set lasted me about 50 - 55k before needing to be replaced, with tire rotation every 5k miles, and never left me stranded. Noise level is minimal on these tires, and they do well in just about any terrain in the Northeast.

Great mud tire!
Hard to find mud tires in stock tire sizes. These are a good value for the price. I've been running these tires on two different vehicles now for about a year and a half, and they seem to be holding up really well, and for a mud tire that's pretty impressive. These Cooper SST mud terrain tires weren't the cheapest but they weren't the most expensive either. Good middle the road value. This particular purchase I only purchased one tire to replace my old warn out spare. Highly recommended by me!

I was complimented on how those four tires look on the back of my truck
These tires were actually reasonable as far as cost and I don't hear any noise level it all and the mileage maybe I lost 2 miles per gallon at the most overall I like the tires they have very good traction and are good in the mud the kids are going to come over here cars on a trailer for a living and this truck was a lifesaver with the tires on it

Great on and off road

Showed up in terrible condition
Bought these for an old-school build with the white wall out and all four tires were scuffed up. One was completely missing the white paint.

Needed new tyres for my LR Defender110...bought some other ones (no names!) from another company! They arrived WRONG SIZE..& it took 3 weeks for them to admit & collect & return payment. Amazon does give you "peace of mind" in that direction - and the tyres are really excellent! A good mix between off-road and road use...shame they are NOT winter-rated! Two years on...(2020) tyres are all good, hard cornering on a wet road they'll slide - but predictably! Good in winter as well - though not EU winter-rated! Wear after 35000Km is very acceptable. Use off road is excellent, fantastic grip (shattered half-shaft actually!). Recommended buy especially if you do any off road/mud travelling
