What is the largest wheel and widest tires that can be fitted onto a G boby without notching the frame? I am looking at some 17x8 reproduction Monte SS wheels and was thinkg about running either 245/45/R17 all around or 245/45 in front and 255/45 in the rear.

From what I've seen, 245/45-17s generally fit without much issue. That's probably the size I'm going to eventually go with.

I was looking at the Monte reproduction wheels but just saw these GTA wheels. Both are 17 in. The Monte wheels are 17x8 and the GTA is 17x9. Both are nice but now I am torn as to which to get.

Upon futher investigating not sure if the GTA wheels would fit easily. they are +12 offset and 5.5 backspacing.

Depends on your package - need to know the cross section of the tire you want to use.

Since they're new and I'm shameless about pics...here is my setup.
17x7 front with 225/50/17 Nitto (17x8 with 245/45 should fit perfect)

17x8 rear with 4-1/2" BS and 255/45/17 Nitto's. I believe the repro SS wheels have less backspace which would be fine.
