Tyre pressures at Zandvoort
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 Zandvoort 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.

Lengths are measured from the OpenStreetMap geometry drawn above; the longest straight is derived from the same line and is approximate. Section names are the venue's, and can belong to any of its layouts.
What Zandvoort asks of a tyre
Zandvoort threads through the dunes with fast, banked corners, including the steeply banked final turn that loads the outside of the car far beyond what a flat corner map suggests. Sea air keeps temperatures moderate and blown sand can take the edge off grip early in a day before the racing line cleans.
The banking multiplies vertical load on the outside pair; do not run them soft
Morning sand on the line lowers grip and temperature until it clears
Coastal ambients: the window arrives later than the forecast suggests

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.
