Hey Everyone,

I have a quick question. Would a 285/40/22 fit on all four corners of a GC SRT8? What is the tallest sidewall that will fit?

there are many tire size calculators on the web. you can compare the overall diameter with stock tires. the stock OD is 29 ". I'm sure you can go oversized a bit, but your speedo will be off. Not that its your main concern I guess if you want to know what the largest size the GC can accomodate.

285/40/22 will be 31" OD. That is 2 inches larger than the stock 29 inches. The rule of thumb (not carved in stone, but generally followed) is that to avoid messing with the ABS systems in cars, you don't increase the OD by more than 5% of the stock OD. 5% of 29 inches is 1.45 inches. So increasing to a tire that is 2 full inches larger than the stockers COULD cause some issues. Now the ABS issue can be address and fixed, but I have no experience in this area.
