GTM Wheels/Tires

[GTM1]

I am pretty sure of the front wheel sizes and offset
but the rear has me stumped.

A 335/30 19 on a 19 x 12 wheel would this work? 53mm offset

or taking it down a bit to a 305/30 19 same rim work?

The more the offset the more the wheel sets out? So too much offset can hit the fender edge?

Thanks

Your rear wheel offset looks good, I figure 52mm offset is perfect for a 12 inch wheel so you are pretty much dead on. (The offset is backwards from what you are asking though, higher offset brings the wheel inside the fender more.)

The 335/30/19 is 27" inches tall, I would stay away from it for sure. The 305/30/19 is about 26.3, so it would work as would a 295/30/19 which would be the best fit from a diameter standpoint. Both the 295 and 305 would be a little narrow for a 12 inch rim, they would be a better fit on an 11" rim with a 46mm offset. The lack of a 335/25/19 is the reason we often run 18 inch wheels but hopefully someday someone will make that size. For now what I consider the best rear tire size if you don't mind the 18 inch wheels is a 335/30/18.
