Our Brembo cars come with a 255 width. Most people stay with that, or
go wider - even up front. Look up the stock tire sizes on a Boss 302. They came staggered from the factory on 19" rims. They are 9 up front and 10 in rear.
Just be careful getting 18" rims on your Brembo. Most 18" won't clear the big brakes. That's why we have 19 - and some 19" won't clear because of the shape of the wheel.
