Tyre Pressures replaces the scrap of cardboard every kart tuner keeps in the toolbox. For each session you log the cold pressures you set and the hot pressures you read straight off track, in psi, for all four corners: front left, front right, rear left and rear right.
With each log you can record the date, the track or session, which tyre set you ran, the ambient temperature in °C and a short note. If you track sets in the Pit Kit's Tyre Sets journal, your active (not retired) sets appear as tap chips so you don't have to type the name. If you are signed in, you can also pick the track from the AVB track library, or simply type it.
The useful number is the rise. For every corner that has both a cold and a hot reading, the app works out the cold-to-hot rise and shows it in the session list, for example "rise FL +1.2 FR +1.4". Chasing a consistent rise session after session is how tuners find their cold settings.
Logs are saved on the phone, so the tool works in the paddock with no signal, and you can open, edit or delete any session. There is no cap on Free. Premium adds PitSync cloud backup, so the history survives a lost or replaced phone.
