About 265/70R16
Factory fitments for 265/70R16 include the Toyota Tacoma — meaning replacement tires in this size see steady demand and broad brand availability. At 30.61″ overall diameter, 265/70R16 turns 659 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 16″ rim pairing is typical for light-truck, crossover, and mid-size SUV applications, so compatible wheels are easy to source new or used. Going one step shorter to 245/75R16 drops diameter by 0.45%, which stays within the ±3% fitment safe zone for most vehicles. Stepping up to 275/70R16 adds 1.80% 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 30.61″ stock diameter (about ±2% in percentage terms) will keep ABS, TPMS, and odometer readings inside the vehicle's designed tolerance.
