195/70R14

About 195/70R14
195/70R14 is less common as a factory fitment but is available as an aftermarket size, so SKU selection is narrower than mainstream OEM sizes. At 24.75″ overall diameter, 195/70R14 turns 815 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 14″ rim pairing is typical for compact-car and economy-vehicle platforms, so compatible wheels are easy to source new or used. Going one step shorter to 205/65R14 drops diameter by 1.03%, which stays within the ±3% fitment safe zone for most vehicles. Stepping up to 215/65R14 adds 1.03% 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 24.75″ stock diameter (about ±2% in percentage terms) will keep ABS, TPMS, and odometer readings inside the vehicle's designed tolerance.
