I'm thinking about replacing my rear wheel to an aftermarket 22x11 wheel (305/30 or 315/30 tire). I'm looking for any information or feedback from anyone about running this size wheel (ride comfort change, offset, front or rear wheel/tire size, etc.). I'm looking at running 245/35/20x8.5 on the front. My alternative rear is a 20x11 with a 305/30 or 315/30.
There have been a few folks that have run up to 24" wheels. It could work, but you will raise the height of the slingshot quite a bit. Offset should still remain as close to factory as possible... +42 in the front +45 in the rear. A great resource I have used is Online Wheel and Tyre Fitment Calculator. Offset, Tyre Stretch and Speedo Error | Will They Fit, it will compare the size you are looking to go to vs the factory set up and show you just how much difference there is.
