I have 7.00 X 15" tires on my CJ-5 with 5.38 axels. Top speed is about 48 MPH. Does anyone know how much 16" wheels & tires would increase speed?

Answer is based on the tire diameter, not the wheel size. It is a straight percentage calculation. If you put on tires that are 10% greater in diameter, top speed would increase 10% from 48 to 52.5
