Tyre pressures at Magny-Cours GP
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 Magny-Cours GP 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 | +2.5 |
| Right front | +2.0 |
| Left rear | +3.5 |
| Right rear | +3.0 |
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 Magny-Cours GP asks of a tyre
Magny-Cours is famous for its billiard-smooth surface, and the tyres notice: consistent contact, readable behaviour and clean pyrometer numbers. The Adelaide hairpin is one of the biggest braking events in France, and the fast Estoril and 180 sweeps provide the sustained load either side of it.
Adelaide's braking zone dominates the front tyres' lap
The smooth surface gives unusually clean zone readings; a good circuit to learn the probe
Sustained sweeps still build shoulder heat despite the surface

Published hot target 30.5 / 32.0 psi at 92°C tread, on a 15°C morning, with the corner figures above: cold set 21.4 / 21.5 front, 22.5 / 22.6 rear. A different car, tyre or morning moves every number, which is what the calculator is for.
