Anyone tried Kumho ECSTA Supra 712’s??? I have a '97 M3 with original oem tires all around. I really need just one rear Michelin Pilot SX MXX3 (one very new, one getting bald) but I can't find any!!! So I guess im going to replace both rear tires. Just wondering how the Kumhos stack up. I know that they won't have as much dry grip, but I am wondering how much less... I am willing to give up a little dry grip for better wet traction, tire wear and comfort as long as it still performs well enough.
