Tire size & stretch
Compare your current setup with the next one. See the numbers before you choose your tires.
Nominal dimensions. Actual tire dimensions vary by model. Check load rating, clearance and the vehicle’s requirements before changing sizes. Speed estimate assumes the speedometer is calibrated to the current tire size.
Compare nominal tire section width with wheel bead-seat width. The drawing is a dimension sketch, not a prediction of the mounted sidewall.
Section width changes with rim width and tire construction. This tool does not approve a stretch setup. Use the exact tire manufacturer’s specifications.
