I have a 2012 Liberty Jet with 20" wheels and P245/50R20 tires with 93.13" circumferance. I have a set of Chrome wheels and Tires (18") from a previous Liberty, P235/60R18 with a circumferance of 91.43".
If I use these, Will the speedometer have a significant error? It's 1.7" on each revolution. I'm thinking about 2% off...thanks all,
