I haven't found too many comments on these tires. There is a review on these tires on off-roadweb.com under "Long-Term Offroad Tire Test Updates." I talked to DC today and the tech said that the 31" tire doesn't have a 3-ply sidewall, but the new Fun Country will have it. The new FC tire in 31" is due to be out next month. Summitracing has them listed on their website, but they're not in stock. There is a $50 rebate that is good until the end of August. I don't think that I can wait that long and might go with the Cooper STT instead.
