Just ordered Cooper STT in 305 55 R20. Any thoughts on fit?? We measured and checked everything and I think they will fit. I have the readylift keys up front.

got a friend running a similar sized tire and wheel on a gmt800 platform. no cranking, minor trimming. a lot of the fitment is gonna depend on the backspace and offset of the wheels you're puttin em on......
i would think with the keys and a little trimming you should be ok. nothing major

I have 33x12.5's on mine with -12 backspace and 4.5 offset. I had a lot of people tell me they wouldn't fit. I didn't trim or bend any metal....very nino plastic trimming.
