## What is Tire Keeper?

Tire Keeper keeps everything about your tires in one place: when you swapped them, where the off-season set is stored, how old each set is, and when it's time to rotate or check the pressure.

■ For drivers with two sets
• Record a seasonal swap with one big button
• Then note where the removed set is stored: at home, at a shop or at a tire hotel, with the ticket number and a photo of the storage ticket
• The Home screen changes its scenery with the set you have mounted: winter, summer or all-season
• See the days until your next swap date (defaults follow your country, and you can set your own dates)

■ For every driver
• Tire sets: maker, model, size, purchase date, tread when new, and the DOT date code (with a guide showing where to find it) to see each set's age
• Inspections: tread depth and pressure for each of the four wheels, laid out on a car diagram, in three colors based on thresholds you choose
• Rotation reminders by distance or months, whichever comes first
• Pressure check and tire age reminders
• A timeline of swaps, rotations, inspections and puncture repairs

■ Your units
km or miles, mm or 32nds of an inch, kPa, psi or bar. Defaults follow the country you choose and can be changed at any time.

■ Your data stays on this device
No account and no sign-up. Your records and photos are stored only on this device. You can export them as JSON or CSV from the share menu.

■ Pricing
Tire Keeper is free to download. The first month is a free 1-month trial with all features. After the trial, these stay free: 1 vehicle, 2 tire sets, all logs, reminders, a photo of each set and of its storage ticket, and file export.
Tire Keeper Pro is a one-time purchase that adds unlimited vehicles and tire sets, photos on each log, and a replacement estimate from your tread records. It is not a subscription, and nothing is charged automatically when the trial ends. Your records are never deleted.

■ Please note
Tire Keeper is a record-keeping and reminder app. It does not judge the condition of your tires. Reminders and estimates are only a guide. An inspection by a tire professional is recommended, and please check your local rules for winter tires.
