front to back rule of thumb?

[jarhead]

I've been measuring my Torino for the Boze wheels and a theoretical tire size.

What should the diameter difference be from front to back?

Back wheels will be 18x10

Front wheels will be 18x8

I can get a 305/40 to 45 on the back, that is a 27.6 to 28.8 diameter

Trying for a 255/40 or 45 on the front, that is a 26.0 to 27.0 diameter.

May have to go to a 245 on the front due to width clearance.

Will it look strange with a 26 in the front and a 28.8 in the back?

Thanks, Joe
