4 GXP rear wheels 18x7 55mm offset, will they fit my '04 GT?

**svanwormer** · 01-25-2017

Has anyone tried the 18x7 rear GXP wheels with 55mm offset on the front of your GP? I was wondering if I ran a 225 tire, would I still clear the spring/strut asm. The wheels are for sale with no tires currently on them. TIA

18x7 isn't wide.

That is the factory rear rim size on the GXP's, which did come stock with 225's. The front's are 18x8 with 255's.

They didn't even rub when I ran 275's.

It'll fit just fine.

I'd go find either a full set of rears or a full set of fronts, nothing staggered. That's dumb.

I realize GXP rear 18x7 (55mm offset) is only 1/2" wider than stock 16x6.5 (52mm offset). GXP fronts have only 40mm offset, so I see how you could run a bit wider tire with those. I was more concerned that using the rears with 55mm offset on the front would be close, being that it's a 1/2" wider as well. Does that make sense? Thanks for your input blueguy!

55mm offset means it is going to sit more 15mm more inboard.

So if i replace an 18x8 45mm offset with a 18x8 35mm offset it will sick out MORE?

Yes, it will stick outboard 10mm (.39") more.

Will the front rims fit rear as well?

From what I've read, people rotate the tires front to back and don't realize the wheels are different width and offset. I have 4 rears that I bought off a guy. Got 225/50/18's mounted just waiting for good weather to stick around.

Are these GXP wheels still for sale? If so, how much?
I am located in PA, but I will make the trip to Michigan to get these.
