About TireSizeHQ

TireSizeHQ is a free tool for finding the correct factory tire size for your specific vehicle — by year, make, model, and trim — without needing to already know your tire size. Once you've confirmed your size, we link you to major online tire retailers so you can compare prices before you buy.

Our fitment data is sourced from a licensed automotive database covering vehicles sold in the United States and Canada. We built TireSizeHQ because most tire price-comparison tools require you to already know your tire size — which isn't something most drivers have memorized. We wanted a tool that starts from what people actually know: the year, make, and model of their car.

TireSizeHQ is independently operated. We're not affiliated with any tire manufacturer or retailer. When you buy through a link on this site, we may earn a commission from that retailer — see our affiliate disclosure for details. This doesn't affect the price you pay.
