215/65R15

About 215/65R15
215/65R15 is less common as a factory fitment but is available as an aftermarket size, so SKU selection is narrower than mainstream OEM sizes. At 26.00″ overall diameter, 215/65R15 turns 776 revolutions per mile, which is the reference point the factory speedometer and odometer were calibrated against. The 65% aspect ratio gives it a balanced sidewall — enough compliance for daily comfort without vague steering. The 15″ 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 195/70R15 drops diameter by 0.98%, which stays within the ±3% fitment safe zone for most vehicles. Stepping up to 205/70R15 adds 1.14% 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 26.00″ stock diameter (about ±2% in percentage terms) will keep ABS, TPMS, and odometer readings inside the vehicle's designed tolerance.
