From my limited experience they are low performing, over priced tires. I ran them for 35,000 miles and they were pretty much junk. Although a less agressive looking design, i am in love with the Michelin LTX A/T2. I currently have 55k on the set im running now. They are warrantied through 60 but i feel they will go a GOOD 5-10 k past that. Quiet on the highway and perform very well in whatever oklahoma can throw at you. A little pricey but well worth checking out IMO.
