I think some of both. I drive up and down highway 45 through West Point up to Saltillo every day. I try to keep it around 60 and don't launch. My first set of tires didn't last as many miles as my second one has, in my mind because I haven't launched. When I first got it, it was kind of a toy I had to show off and I am pretty sure I shortened the life of my tires by doing so.That’s solid. Ran into someone the other day who said they were replacing every 20k on average. Perhaps driving style or worse roads where they live?
