Will 275/30R19 tires work on my 987S?
 

I want to buy Yokohama AD08 tires on my 2005 S. The stock rear tire is 265/35R19. The closest height match from Yokohama is a 275/30R19. So stock is 26.3", and the Yoko is 25.6" in diameter.

Will this cause problems with PSC or ABS?

Well, we're all going to know in about a week because I ordered the tires.

I have 275/35/18 PS2's and I had to squeeze them in there, they fit but just barely. a credit card is all you can fit between the tire and the strut. Let us know how it turns out

FYI, I got the tires mounted and I've had no troubles so far with the 275/30/19s on the rear of my 987S.
