Thanks Keith. Great info.
My car ( A Lexus IS ) eats tire aggressively and is well documented here: All about Lexus IS premature inner tire wear - ClubLexus - Lexus Forum Discussion
I hadn’t known before purchasing my car that the Lexus IS would force me to change tires every 15k-20k miles, despite the tire brand ( continental ) claiming I can get about 45k-50k miles on them.
My car is poorly designed by Lexus, and, as a result, I’ll need to change tires pretty frequently.
