Hi guys! I'm running 315/25/19s now for years. No real issues accept inner tire wear - like only the first inch down to steel and mainly on passenger side - otherwise tires have good tread remaining. I suspect my toe is out. Going to check alignment tomorrow but rears need replacing.
Im gonna change to 305/30 and replace with Supersports but I'm running PS2s on the front that are still in great shape. Yea yea I know don't mix compounds but I can't keep spending 500+ each on rear tires over a theory. Get this - PS2 are more expensive than Supersports by $200 each!! No way! With Supersports you get twice the tire at half the cost lol!

 

Well, I've just ordered PSS for the front and I have PS2 on the rear.

Here is my post if your interested.

the irony is some of that run oem gt2 sizes can't get the PSS since they aren't made. i wonder how the decision(s) as to what sizes get made ARE made. presumably it's based upon market size. but no 315/30/18 is plain dumb. all i need is a PSS in an oem fitment and i'm done. sheesh.
