I have a 2006 mustang gt. I am getting black fr500 18x9 front 18x10 rear. I want the sidewall to be the same all around or the back sidewall taller. I dont want the front to have a taller sidewall. Will 255/45-18 in the front and 285/35-18 do this for me. Thanks!

 

yes they will look very close as far as sidewall height goes.

 

There is going to be a difference in diameter, circumference, and side wall with thoes sizes. If you can get a 255-40 tire that will make it almost identical.

That should help you figure out what you need. But they will look about the same.

 

Cool. Thanks.

 

a difference, yes...but it would look fine that way.

 

That tire size calculator site is awesome!! Thanks for that!
