Wet Weather Track Tyre Pressures

Last updated: 3 July 2026 · Estimated reading time: 3 minutes

Wet track tyre pressures are not just dry pressures with a random number added. The tyre usually runs cooler in the wet, so it may not gain as much pressure as it would in the dry.

Common wet approach

Many drivers start slightly higher cold in wet conditions because the tyre may not build as much heat. The final target still depends on tyre, car and grip level.

What to avoid

• Running very low pressure and rolling the tyre onto the shoulder.
• Leaving dry-session pressures in after conditions change.
• Ignoring tyre temperature because the car feels safe at lower speed.

Best workflow

Set a sensible baseline, run a careful session, then check hot pressure straight away. Wet conditions change quickly, so keep notes.
