Tire Keeper is an iPhone app that keeps track of your tires: when you swapped between winter and summer tires, where the off-season set is stored (at home, at a shop or at a tire hotel, with the ticket number and a photo), how old each set is (from the DOT date code), tread depth and tire pressure checks, and when the next rotation is due. Reminders arrive on your iPhone at the right time for your country. All records and photos stay on your device. No account required.
