3800 rims and tire question

[smug]

Will an 18X8 inch rim with 245/40ZR18 tire fit on a gp. I have heard of some clearance issues in the rear. The rims has a 40mm offset.

i have 245/40/18 on my 18's. thinking of going to 245/45/18.

But yes it will fit especially if your not lowered. Not sure if you have springtech springs or struts.

ya im lowered on springtech, cheap but it works. I didnt know if the 245 would work in the rear cuz of the trailing arm and the side of the rear tire is kinda close. Right now i the 16X8 eagles with a 38mm offset with the stock tire size and i can only slide my fingers betweem the tire and the trailing arm. Thanks for the help

I have 245/45R18's with a +45 offset and it fits fine. They were pretty close to the stock trailing arms, the GMPP arms will give you more room.

The more offset you have the farther away it will be from the trailing are right? Or is it the other way around?

245/45/18 is the way to go and besides we live in a cold place... rims on 40 and 35 get dented very easily

The cold = Potholes

The more + offset the further in the wheel will sit.

Offset is the difference between the wheels center line and the actual mounting surface. So positive offset pushes the mounting surface further out past the wheels center line.

Brian,

Dont know what kind of rims you have. I just got 4 245-40RZ-18 delivered Friday for my 8" 077's. Yea, wife is pissed. They still are sitting in the foyer.
If you havent purchased the tires yet check out VULCANTIRE.COM.

Check out my post in CLASSIFYEDS on the Falkin tires. They also have the rim protector....I went with the FK-415 245-40RZ-18s ($576 shipped). There isnt supposted to be any rubbing issues VIA HHP magazine and some of our members.

They also have a cheaper ZIEX-512's at $512 shipped from PA.

Your looking for a 38+ mm offset for our cars.
