Snap the SidewallFREE

Point your camera at the tire sidewall. Flashlight turns on automatically. AI reads the DOT code, tire size, brand, model, speed rating, and more.

Get a Safety ReportFREE

AI calculates tire age, decodes all specs, checks NHTSA recalls, searches for known issues, and gives you a clear safety verdict. Know in seconds if it's time to replace.

Did You Know?

6 Years

Tires expire after 6 years regardless of tread depth. The rubber compounds degrade from the inside out, even if the tire has never been driven on. NHTSA recommends replacement at 6 years, and most manufacturers agree.

9,000+

Tire-related crashes happen annually in the US. Aged, underinflated, and worn tires are among the leading causes. A blowout at highway speed can be fatal — and it's almost always preventable.

Hidden in Plain Sight

Most people have no idea tires have a manufacture date stamped on them. The DOT code on your tire sidewall is its birth certificate — four digits that tell you exactly when it was made.

The DOT Code

The last four digits of the DOT code are the date: first two = week, last two = year. "2319" means week 23 of 2019. Every tire has one. Now you know where to look.

How Safety Check Works

Safety Check uses AI-powered web search to analyze your tire against multiple safety databases — giving you a comprehensive report in seconds.

It checks:

Tire age vs. NHTSA 6-year replacement recommendation
NHTSA tire recall database for your specific brand and model
Known complaints and defect reports
Full tire size decoding (width, aspect ratio, rim diameter)
Speed rating and load capacity in real-world units
Treadwear rating comparison to category averages

TireOrNOT is a visual scanning tool, not a professional inspection. AI can accurately read the DOT code and decode tire markings, but cannot measure tread depth or detect internal damage. Always have tires inspected by a qualified technician for safety-critical decisions.
