I'm surprised the Chineese tire rant hasn't started yet . . . oops, I see it HAS started . . .
I have Marathons on my Surveyor. They have about 20,000 totally trouble free miles on them and are going strong. They've been in all day 90 degree tows; on nasty rocky national forest service roads. Totally happy with them. Flawless.
By the way, check out the Kumho 857s. I might get these next time because of the D load rating and the 99 mph speed rating. They're 14 inch only though I think.
