About 245/35R19
245/35R19 is less common as a factory fitment but is available as an aftermarket size, so SKU selection is narrower than mainstream OEM sizes. At 25.75″ overall diameter, 245/35R19 turns 783 revolutions per mile, which is the reference point the factory speedometer and odometer were calibrated against. The 35% aspect ratio gives it an ultra-low-profile sidewall tuned for maximum steering precision — at the cost of ride comfort and rim protection. The 19″ rim pairing is typical for full-size truck, premium SUV, and sport-sedan platforms, so compatible wheels are easy to source new or used. Going one step shorter to 235/35R19 drops diameter by 1.07%, which stays within the ±3% fitment safe zone for most vehicles. Stepping up to 225/40R19 adds 1.30% 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 25.75″ stock diameter (about ±2% in percentage terms) will keep ABS, TPMS, and odometer readings inside the vehicle's designed tolerance.
