TirulatorFrequently Asked Questions
Q: Why is nothing displayed on my monitor and the calculator is not working?
A: In the vast majority of cases, this is because JavaScript support is disabled in your browser. Check it in the settings of your browser. We have tested all calculators in almost all existing browsers and it should be displayed correctly. If JavaScript is enabled and you still have a problem, we recommend that you just try to open our calculator through another browser.
Q: Where can I get the original tire/wheel size for my vehicle?
A: You can find your vehicle's original factory tire size and wheel size on the sticker located on the driver's side door jamb (B-pillar). Alternatively, you can check your owner's manual or look up your vehicle information on online databases or inspect the sidewalls of the currently installed tires.
Q: How to read tire and wheel sizes?
A: Please check out our Education Center, where you can learn all about tires and wheels.
Q: Does tire size make a difference?
A: Changing your tire size affects how your car drives, handles, and uses fuel. The width affects grip and fuel economy, the sidewall height affects ride comfort, and changing the overall rolling diameter can throw off your speedometer and driver-assistance systems. Installing the right tires on your vehicle is essential for the overall performance and safety of your vehicle. Always check the placard on your driver's door jamb for factory-approved alternative sizes before buying.
