Tyre pressures at Paul Ricard
The lap, to scale. Track outline © OpenStreetMap contributors (ODbL).
How hard a circuit works each corner of the car shows up as tread temperature, and temperature is what sets pressure. GripCalc carries corner heating figures for Paul Ricard as a starting point: how much hotter each tyre runs over the session's base temperature, from the layout's mix of corners and load. They pre-fill the calculator when you pick the circuit, and your own pyrometer readings refine them from the first session.
| CORNER | RUNS HOTTER BY, °C |
|---|---|
| Left front | +2.0 |
| Right front | +1.5 |
| Left rear | +3.0 |
| Right rear | +2.5 |
ESTIMATED — class-based starting values over an 85°C session base, derived from this layout's type (direction, speed profile, load), and shared with circuits of similar character rather than measured here. Not gospel: enter your own pyrometer figures after a session and they take precedence.
What Paul Ricard asks of a tyre
Paul Ricard is flat, spacious and engineered: long runs including the Mistral straight, the very fast Signes right-hander at the end of it, and famous painted run-off instead of gravel. Signes is the corner that matters to tyres: arriving at maximum speed onto a sustained right after the tread has cooled down the straight.
Signes loads the left side at maximum speed after a long cooling straight
The abrasive high-grip surfaces in the braking zones work tread quickly
Flat and exposed: wind changes braking points and loads more than elevation would

Published hot target 30.5 / 32.0 psi at 92°C tread, on a 15°C morning, with the corner figures above: cold set 21.5 / 21.5 front, 22.6 / 22.6 rear. A different car, tyre or morning moves every number, which is what the calculator is for.
