Direct substitute sizes

Plus / minus sizing options
For a 215/13R21 you can upsize to 225/7R22 (plus-one) to fit a larger wheel without changing the speedometer reading, or downsize to 205/20R20 (minus-one) for a softer ride or winter setup. Both stay inside the ±3% diameter tolerance that ABS and TPMS systems expect.
