Price: $219.00
Pros: Look awesome not really loud on road these are the new STT pros not listed
Cons: non just got them
Recommended? Yes

Comments: These are the Cooper STT PROS and they were not listed since they are a pretty new tire. I just got these and I love the aggressive look they are fairly quiet on the road but just a mellow hum not over bearing. Did alot of research on these tires and they got some really good reviews. Have not done any rock crawling or crazy off roading yet but looking forward to it soon.

Pros: Wear is good with tire pressure monitoring No problem off road wet or dry Great on wet pavement
Cons: None
Recommended? Yes

Comments: Bought Five 33x12.50x15 from local shop. Great all around tire. Just like any other mudder, have to monitor tire pressure for good wear. I'm running 32 psi street, 20 psi on trails. They are good on rocks too. Would recommend to anyone that trail rides with jeep.

Pros: Overall great tire, both on road and off road.
Cons: None Yet
Recommended? Yes

Comments: I've had my Cooper STT for several years now and they are doing a great job for me. Tread wear is great so far and so is the tire's capability. I've had it 4-wheeling in Utah, Arizona, Colorado, Utah, Idaho, and Montana. Different terrains and conditions and so far so good. A lot of good tires out there, but I would recommend Cooper's for their price, style, and performance.

Price: $800.00
Pros: resonably quiet, great off road, good tread wear
Cons: hard to balance them
Recommended? Yes

Comments: I bought a set of these about 5 months ago for my '03 TJ through the tire wholesaler that my shop deals with. I have absolutely no complaints about them. Even with some seriously agressive tread they're still pretty quiet at all speeds, and I regularly drive long distance on the highway. Off road I have had no problems with them, they hold up very well and can take a beating. Noticed a few people saying they weren't good in the rain, personally I haven't had any problems with them on wet pavement. Overall they ride and perform well for an off-road tire. Haven't had them in the snow yet, so I can't speak for their performance there, but I would definitely recommend them to anyone who wheels on the weekend and spends all week driving on the road (like me). Only complaint is that they were hard to balance out, but then again I had to do that myself and I don't know how much of that had to do with my rims being bent.

Comments: big improvement over my BFG AT's. they are very good in the rain where I used to hydroplane with my BFG's. They are louder but I'm in a TJ so it's nothing new

Price: $135.00
Pros: Aggressive tires, triple ply sidewalls, pleasant hum on the road.
Cons: Not well siped for packed snow and ice.
Recommended? Yes

Comments: Ordered these from tirecrawler online. Saved a decent amount of money this way, though I found out Discount tire would have price matched locally. I had the tire shop sipe the tread, as they are lacking enough sipeage for good hardpack snow, and ice traction. It helped with straight line traction, but my front tires still slide out when turning some. In fresh snow, they dig and bite good. Haven't had time to take them offroading much yet. Only gripe I really have is the amount of weight it took to balance. Pleasant road hum, isn't unbearable at all, but frequent rotations will be needed.

Pros: good in mud and lower difficulty trails
Cons: not too good in rain or crawling
Recommended? Yes

Comments: These tires look great and i love the size at 35". They don't look sluggish and give me some extra clearance. There is a little bit of road noise but i would recommend these just because of how nice they look

Price: $150.00
Pros: Great MT for the price. Great on road and off road. Quiet and drivable going down the highway.
Cons: None yet.
Recommended? Yes

Comments: Great combo tire if you want both highway manners/quietness and off road capability. Maybe not your choice if you are an extreme off roader. If you want something that is good on ice, get yourself a set of studded winter tires. MT's are notoriously bad on ice and wet highways....not their intended use. I would buy them again and again for my style of off roading and daily driver use. My tires: 30X9.5X15

Price: $160.00
Pros: quiet, tough, last awhile
Cons: kinda heavy, but worth it
Recommended? Yes

Comments: I gave it 4 stars, just because they are not the best on ice, and I can loose traction on wet roads. However dont let that scare you away. These tires are awesome! I wouldnt hesitate to buy them again. I got about 40k out of them and still have some tread left. Outstanding tire, great in the mud

Pros: Awsome tread
Cons: Do not have any :)
Recommended? Yes

Comments: Awsome tread .... but you need to shop around cause price is very changeable on these tires .... bizrate is the place to shop around as long as you are able to install them yourself .... i did! These tires are just as good 32" tire .... i have done better on courses than the jeeps i was with that had 4" lifts and 32" tires!

Recommended? Yes

Comments: I bought these tires for a DD WW Jeep YJ 33x12.5x15. I have tested them on road and they are extermly quiet. In the mud they did really well, and on the granite they did really well. I will see how they feel in 6 months.

Price: $1,255.00
Pros: Hook up to rock well, well mannered on road (quite, good in snow/rain)
Cons: Marginal cleaning abilities
Recommended? Yes

Comments: I found the Cooper Discoverer STTs to be very well mannered on road. They grip and brake on pavement well in rainy/icy conditions. Excellent in snow. They seem to wear well, though I only put 8,000 miles on mine before upgrading to 37s. They hook up to rock very well, and hold the bead at 10-12psi on the stock MOAB wheel. Their cleaning abilities in mud are marginal - this was their only negative that I could find.
