Tire pressure is the cheapest setup change in karting — and the easiest one to forget. LapperSnapper stores pressures with each session, so your data and your setup live together.

Steps

1. Open a session and go to the Overview tab.
2. Find the Tire Pressures section.
3. Enter the four corners — front-left, front-right, rear-left, rear-right — in bar or psi (switch units in Settings).

How to use it

• Log the pressures you set before the run, right after you set them — gauge in one hand, phone in the other.
• Back in the paddock, compare sessions: same track, different pressures, and the lap chart tells you what the change was worth.
• Over a season, your history becomes your own reference book: what you ran at each track, in what conditions, and how it went.

Tip

Pair pressures with a vehicle assignment (Assign sessions to a vehicle) — pressure conclusions only transfer between sessions on the same machine.
