Tiretime vs TireOptic

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.

TireOptic turns your phone camera into a tire inspection tool. Scan a tire and see, in plain numbers, how much tread is left, how old the tire is and whether it needs to be replaced — no gauge, no guesswork, no appointment. WHAT YOU CAN SCAN Tire sidewall — about 10 seconds Read the tire's brand, model and size straight off the sidewall, plus the DOT code and the production date it encodes, so you know exactly how old the tire is. Uses no scan from your balance. Tire measurement — about a minute Measure tread depth in millimeters on all four tires, left front to right rear. TireOptic analyzes the wear across the tread and turns it into a report you can keep, share or download as a PDF. WHY IT MATTERS Tread depth is what keeps your car connected to a wet road. As it wears down, braking distance grows and grip in rain drops sharply. TireOptic makes that invisible number visible: • Depth per tire in millimeters, measured across the tread • Color-coded condition — healthy, wearing low, or critical • Clear warnings such as "tread critically low — replace this tire" • Uneven wear across the tread surface, so you can catch alignment and pressure problems early • Tire age from the DOT code, because rubber ages even on a car that barely moves EVERYTHING IN ONE PLACE • Reports — every scan is saved with its date and vehicle. Open a past report any time, share it, or download the PDF. • My vehicles — add your cars, keep each vehicle's scan history separate, and see at a glance which one needs attention. • Matching tires — once TireOptic knows your tire size, it shows you tires that fit, so replacing them doesn't start with a size lookup. • Help center — short, practical answers on scanning in low light, camera positioning, retaking a failed scan, and reading your report. MADE FOR DRIVERS AND FOR TEAMS Use it on your own car, or on a fleet: taxi and rental operators, dealerships, service shops and tire retailers can scan vehicle after vehicle and keep a documented, shareable record of tire condition for each one. Business accounts are supported. SIGN IN THE WAY YOU PREFER Phone number with a one-time code, Google, or Apple. Your account keeps your vehicles and reports in sync. HOW IT WORKS 1. Choose what you want to scan — sidewall or full measurement. 2. Follow the on-screen guide and move the camera slowly along the tread. 3. Get your result in seconds, with a summary of what to do next. Best results come from a clean, dry tire in reasonable light, with the camera held at the distance the on-screen guide shows. GOOD TO KNOW TireOptic gives you an indicative measurement to help you decide when to have your tires looked at. It is not a legal-metrology instrument and does not replace inspection by a qualified tire professional. Always follow the tire and load recommendations in your vehicle's manual and the legal minimum tread depth in your country. Camera access is required to scan. Location is used only to show tire options and prices available in your country. Questions or feedback? Reach us from Profile → Support inside the app.
