Carlisle was good about getting 2 new tires out to me after I discovered splits in 2 brand new tires with apprx. 2000 miles on them on a utility trailer. I had the new replacements within 2 weeks after I called them. I didn't put the new ones on the trailer, I had 2 17K miles General radials Load Range E tires installed instead. The new carlisles are in the shed till I decide to sell them. I don't trust them with the heat and high speeds (65)here in south TX.
