About 235/70R16
235/70R16 is less common as a factory fitment but is available as an aftermarket size, so SKU selection is narrower than mainstream OEM sizes. At 28.95″ overall diameter, 235/70R16 turns 697 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 245/65R16 drops diameter by 1.43%, which stays within the ±3% fitment safe zone for most vehicles. Stepping up to 245/70R16 adds 1.90% 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 28.95″ stock diameter (about ±2% in percentage terms) will keep ABS, TPMS, and odometer readings inside the vehicle's designed tolerance.
