Mine read approx 3% below actual speed with stock tyres so now reads around 0.5% higher. In real terms this means at 100kmh on the speedo my GPS speed is still showing My personal rule is no less than the placard on the door jamb, no more than the pressure on the sidewall of the tire. The max pressure on the side of the tire is for carrying the max load, that may be well above the max load for the vehicle. Higher pressure will make the sidewall stiffer for cornering and steering response. The goal is to calculate the height of the sidewall of the tire and then add the size of the wheel to it. Take 265 and convert to inches by dividing by 25.4 (265/25.4 = 10.4" wide) Now using the aspect ratio (.75) determine the size of the sidewall by multiplying the 10.4 by .75 to get 7.8". 225/70R16 SE 1. 215/75R15 2. 225/75R15 1996 Jeep Grand Cherokee Tire Sizes Laredo 1. 225/75R15 2. 245/70R15 Limited 255/75R17 ~31.6" @ 50% tread (8/32) - same as new 265/70R17. 255/75R17 ~31.3" @ 25% tread (4/32) Another idea: To compensate for a smaller spare, you could measure the mounted spare wheel center to ground and then air down the opposite side tire so the height is similar.
