No warranty issues with going with Michelin.. No problem. Plus your car is probably out of warranty or will be soon, and before you buy an "extended" warranty, read up on what is covered, almost makes it not worth it.. Several threads on this topic. Mine just ran out this month, and I decided to "self fund" any warranty issues.that’s helpful, sounds like the first owner used it in a similar way. I’d likely also switch out for PS4S’s asap. Bit of a shame they are so new. But what I understand is that it greatly enhances the pleasure… no warranty issues with going to Michelin?
