I got a speeding ticket in my g mas car which is a 2001 Nissan sentra and I need to barrow 2 rims that are aftermarket and bigger then her stock ones so Ican go get it calibrated and it will show that the speedometer is defective her rim is a 15inch so i guess anything bigger will thow it off somewhat i will pay you to use them for how ever long it takes and not a min longer. I guess this is my only option to try and get out of it unless someone else has a better idea please let me no thanks
