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

I prefer matching sidewall over matching OD. but that is just my preference.

I've got 255/45/18s up front 27.0" overall and 295/40/18 rear 27.3" overall.

When I replace tires again I'm going 40-40 as sometimes the 45 up front looks bigger from certain angles even though it's .3" shorter overall.

I'd get some bald tires and play with sizing before you buy... .02 cents.

Thank you for all the replies, it makes more sense now.
