Tiretime: DOT Tire Date & Plant Decoder
Is your tire too old to be safe? Tires degrade from the inside out. Even with "good tread," a tire over 6 years old can be a safety risk. Tiretime is the fast, reliable way to decode the US DOT Tire Identification Number (TIN) and know exactly when and where your tires were made.
Whether you are buying a used car, inspecting an RV, or checking your trailer tires before a road trip, Tiretime provides instant clarity.
Key Features:
Date Decoder: Instantly convert the 4-digit DOT code into the month and year of manufacture.
Plant Code Directory: Identify the specific factory and manufacturer for your tires.
Safety & Recalls: Direct link to reputable legal resources for official manufacturer/plant recall checks.
RV & Trailer Ready: Ideal for vehicle types where tires often "age out" before they "wear out."
Lightweight & Fast: Designed for quick use in driveways, tire shops, or car lots.
Our Privacy Philosophy
I built Tiretime because I could never remember these codes myself. I value your privacy as much as my own. While we use standard tools to keep the app running and show a small banner ad, we do not track who you are or what tires you are looking up.
What we collect & Why:
Performance Data: We see basic info (device type, OS, and general region) to ensure the app works on your phone. We purge this after 90 days.
Anonymized Analytics: We use Google Firebase to see which features are popular so we can make the app better.
Ads & Transparency: The free version uses Google Mobile Ads. If you prefer a completely clean experience, a one-time 99¢ "Pro" upgrade removes ads forever.
Support: If you email me for help, I’ll have your email address to reply to you. That’s it. I delete support logs within 2 years.
Integrity: We monitor for abuse and scraping to keep our systems fast and free for everyone.
No hidden tracking. No data brokering. Just a utility that works.
