Can I upgrade to larger tires?
Decide if larger tires make sense: diameter tolerance, clearance, load ratings, AWD circumference rules, and how to use a calculator before you buy.
“Larger” can mean width, diameter, or both
Wider tires can add grip in some conditions but require compatible rim width and enough fender clearance. Taller overall tires can add ground clearance but may rub and can shift speedometer accuracy. Decide which “larger” you mean before shopping.
Use geometry first
Compare your stock tire to a candidate in the calculator. If overall diameter drifts far, revisit whether you have recalibration options and measured clearance for full suspension travel.
AWD caution
Some all-wheel-drive systems are sensitive to mismatched rolling circumference across axles—even “same label” tires with uneven wear can cause issues. Follow OEM guidance.

Try the free tire size calculator
Open the interactive tire size calculator to compare diameters, see a wheel size comparison side by side, and review a speedometer difference table before you buy tires or wheels. It works like a quick tire fitment checker for geometry—not a substitute for a professional install bay.
