Oh hell yea! Thats almost a 28" tall tire, and if you are a stock geared cobra, you dont want a 28" tall tire unless you have 700rwhp or better. Plus you need like a 12" wide wheel or wider to fit that width wheel. Just put a 315/35-17 on a 10.5" wide wheel and be happy.
I see this is your first post. Welcome to the forum. Try using the search feature here and over in the suspension subforum. Tire questions are best answered over there.
Thanks for your help. I was going to move to a CCW LM20 18" wheel, and put the Toyo on that - which is about 26.5 inches, but it fits the wheel well nicely and looks great.
Until I can afford that $4,000, I was thinking of replacing the 315 X 35 X 17 Sumitomos with a Toyo. I see they are 25.6 OAD so that probably works better.
