Tire question.
 

Looking at buying the AM 18x10 Oem look wheels. I want to leave the stock tire up front as Ive just put new ones on. The rear i was thinking 275/45. Would this be balcance as far as height? Or do yall have any better suggestions?
Thank you for any info.

Thank yuh.

I have a set of 18x10 Oem replicas in black if you're interested. They aren't perfect but I will make a deal on them.

Really? Damn it's just that my front are oem.

You would prob want to have these redone the outide edges are scuffed I have drag radials on them. So I took them on and off alot and wasnt careful. You could prob have them painted to match the stock color for a fair deal. Ill take $75 for them. They still have drag radials on them but they are pretty much done.

I will pm you

285/40/18 295/45/18 305/40/18

These sizes would all work pretty well
