Glad Carlisle took care of the issue. I`m running the same tire in a load range "E" and have no issues. I just replaced my Carlisles with another set. the OE tires were China bombs that lasted a year and a half and about 1k miles! I installed the Carlisles back in 09 and they lasted 5 years before one of the belts separated last year in IN. no blow out just noticed it on my usual walk around. those tires had close to 10k miles. I just installed the other 3, 2 weeks ago with the same Carlisle. I`ve had great luck. When I was doing my research the failures of the Carlisles all seem to be in the C and D ratings, the E`s don`t seem to have the failures the others do.
Good luck!
