About 265/70R18

Factory fitments for 265/70R18 include the Nissan Titan, Toyota Land Cruiser, Toyota Sequoia, Toyota Tundra — meaning replacement tires in this size see steady demand and broad brand availability. At 32.61″ overall diameter, 265/70R18 turns 619 revolutions per mile, which is the reference point the factory speedometer and odometer were calibrated against. The 70% aspect ratio gives it a tall, compliant sidewall that absorbs bumps well and protects rims off-road. The 18″ 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 285/65R18 drops diameter by 0.06%, which stays within the ±3% fitment safe zone for most vehicles. Stepping up to 275/70R18 adds 1.69% 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 32.61″ stock diameter (about ±2% in percentage terms) will keep ABS, TPMS, and odometer readings inside the vehicle's designed tolerance.
