Why We Built TireSpy
Most drivers check their tire tread. Almost nobody checks their tire age. Yet rubber degrades over time regardless of how much tread remains — and aged tires are a leading cause of blowouts and accidents.
We built TireSpy because we couldn't find a simple, free tool that gave drivers a clear answer: are my tires safe or not? Not a vague explanation. Not a sales pitch. Just an honest verdict based on the date stamped on every tire.
TireSpy is free, requires no signup, and stores no data. Your DOT code never leaves your browser. We earn a small commission if you buy tires through our recommended retailers — that's how we keep the lights on.
Make tire safety information accessible to every driver, not just those who know where to look.
