About 285/45R22
Factory fitments for 285/45R22 include the Lincoln Navigator — meaning replacement tires in this size see steady demand and broad brand availability. At 32.10″ overall diameter, 285/45R22 turns 628 revolutions per mile, which is the reference point the factory speedometer and odometer were calibrated against. The 45% aspect ratio gives it a low-profile sidewall that delivers sharp steering response but transmits road imperfections. The 22″ rim pairing is typical for heavy-duty, off-road-lifted, and show-build applications, so compatible wheels are easy to source new or used. Going one step shorter to 275/45R22 drops diameter by 1.10%, which stays within the ±3% fitment safe zone for most vehicles. Stepping up to 265/50R22 adds 1.04% diameter — also inside the safe window, with marginally taller ride height. If you are shopping for a direct replacement, any tire within roughly ±0.7″ of the 32.10″ stock diameter (about ±2% in percentage terms) will keep ABS, TPMS, and odometer readings inside the vehicle's designed tolerance.
