Sizing Help - 18x9.5 Square Set Up

MyNeeds101 · 11-01-2011, 07:48 AM

Wondering if 18x9.5 square set with a 30 Offset all around up will work on my coupe.
Currently running an 18 inch staggered set up with the usual
225/40 fronts
255/35 rears

If this square set will fit, what would I need to run for tire sizes? My thought is that the same sizes above would work... no?

Why would you want to put staggered Tires on square rims?

What is your suspension setup?

No offence BUT the fact that you are asking this question, means you likely aren't prepared
to mess with ride height, camber, fender rolling needed to pull off those specs.

to put it simply, too agressive. Try 9 inch rim 35 offset

I would not use the same tire size up front as I would on the rears despite being "square".

From all the threads I have read, a 9.5 requires a narrower tire for the front to prevent rub.

I am trying to determine if the 225 is acceptable or not.

A square tire and square wheel width has been done before. There are many examples on the forum.

I have been searching, but I am unable to confirm the correct wheel offset.

I am looking to run a similar configuration.

18x9.5" Offset is +43mm with 255/35 tires

Any help would be appreciated. Thank you.
