Why CompareWheels
Most wheel and tire sites are either thin affiliate stores or marketing pages dressed up as guides. We build the opposite: data first, opinions second. Every fitment row has a source, every wheel spec is traced to a manufacturer page or industry database, and the calculators are pure formulas you can verify with a calculator and a ruler.
