Goodyear MT/R w/Kevlar @ 32x11.5r15
Pavement: 7
Gravel: 7
Rock: 8
Mud: 9
Snow: 2
Price: C$1000 for 4
Purchased in 2009. Roughtly 40'000kms on them with some descent life on them left.
Pavement: It's a heavy tire. Good tire in dry and in wet and doesn't feel any more slick in the rain. It makes some good noise on the highway, but I don't care about road noise, but my stereo is louder, and and my exhaust is even louder. I perfer a performing tire and will give up noise for that. They do get hard to balance as the wear.
Gravel: It's gravel, nothing fancy. Does kick up some rocks, but I would expect that of any off-road tire, but I rarely do gravel roads.
Rock: Grips great. I've offroaded with them (accidentally) at 12-14psi. They hold and grip well with a lot of flex.
Mud: I've always been amazingly surprised at how well they work in the mud, where I've made things look easy (always a plus to get rep points when running with Jeeps) even compared to other trucks using dedicated aggressive mud tires. Like Intender, I usually only get stopped when I'm burried to my frame.
Snow: Horrible. I've been a firm believer/user of winter tires, and this is no substitube. I've had to put it in 4WD just to get up small inclines otherwise it would spin. In Quebec LT rated tires were legal to use as a snow tires until this year, now it's anything with the snowflake symbol, including M+S. The MT/R Kevlars. I haven't tried playing around in deep snow, but snow covered roads, I don't like them at all. They're slick when the temp drops below freezing.
Thread Life: They pretty good for wear, but I could see them wearing quickly if you use them as a DD tire. At first I swapped with my street tires and only used them for off-roading. In the winter they don't get used, and with having the car in the last 3 years, I tend to drive that more in the summer over the truck since she hibernates in the winter.
Final: Highl Recommend them, especially for an all-rounder off-road/expedition vehicle that will see some serious terrain and obstacles. When I replace themm it'll be the same tire but in 33".
Yokohama Geolandar I/T (Winter Tire) @ 31x10.5r15
Pavement: 8
Gravel: 6
Rock: N/A
Mud: 6
Snow: 9
Price: C$1000 for 4. I was quoted $175/each this winter for replacements
Purchased in 2008. Roughtly 70'000kms on them and they're due to be replaced soon.
Pavement: Light tire with not much noise. They grip well in the rain and even rain just above
Rock: Done some off-roading with them, but never on rock.
Mud: These work surprisingly well for off-roading. Nothing amazing, but when an impromptu off-roading trip, they work, even in mud, but you need to drop the tire pressure way down. Stay moving and they'll keep you going, but once your stopped, you're stuck.
Snow: Awesome tire for running a non-studded snow tire (legal in Quebec before of the ice base the road form in the winter), but I don't really believe in studs. I've driven in the worst winter had thrown at me and I've never been stuck or stranded or had lost control nor ended up in a ditch. With these tires I'll drive my truck anywhere, any time, in the winter. They drift very well with great control and snap back quickly when you let off the gas. it's a great winter hooning tire
Ice: Ice is tricky, especially being studless, but they work very well and have gotten to places and back to where people couldn't, but you need to drop the pressure down to 20, cause at ~35psi on iced-over freezing rain covered roads, they don't work miracles.
Tread Life: With 6 years and 7 winters under their belts, they about due, and considering they recommend replacing a tire after it's 7 years old, it's good timing. So they last as long as they're needd to last, no more, no less, and I've found some cracking along the length of the tires when I pulled them off this spring. So they'll should be replaced for next winter.
Final: A great tire, but limited in size, 31's being the biggest for a 15" rim; 275, 285 and 315 available for a 16" it seems. Would get them again in 32-33 if I could to get more height/clearance, so I'm undecided on what to do for replacing them, but getting another set of them in 31's, I couldn't go wrong and wouldn't be surprised if I went that way.
