About 265/50R22
265/50R22 is less common as a factory fitment but is available as an aftermarket size, so SKU selection is narrower than mainstream OEM sizes. At 32.43″ overall diameter, 265/50R22 turns 622 revolutions per mile, which is the reference point the factory speedometer and odometer were calibrated against. The 50% aspect ratio gives it a moderate sidewall suited to sporty street driving and responsive turn-in. 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 285/45R22 drops diameter by 1.03%, which stays within the ±3% fitment safe zone for most vehicles. Stepping up to 275/50R22 adds 1.21% 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 32.43″ stock diameter (about ±2% in percentage terms) will keep ABS, TPMS, and odometer readings inside the vehicle's designed tolerance.
