Thanks for the answers guys.
I think I'm going to try and find a set of 275's and put those on the car to see if I can get some additional grip. The P zeros are alright but there is more on the table to get.
Hey Guys,
What is the widest Tire/Rim combination I can fit onto my car (PP Ecoboost) while still staying in FS?
My car runs 19'9's on all four corners with the 255 P zeros but I want to see If I can get a 9.5 or 10 inch rim with tires on without bumping my class to FSP.
