Tyre pressures at Oulton Park International
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 Oulton Park International 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 | +3.0 |
| Right front | +2.0 |
| Left rear | +4.0 |
| 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 Oulton Park International asks of a tyre
Oulton Park is the UK's rollercoaster: crests, compressions, cambered corners and genuine kerbs, threaded through parkland. The International layout adds the Fosters loop and the island section's direction changes. Vertical load cycles are as big a factor as lateral ones, and pressures that survive Oulton's compressions are earning their keep.
Compressions at Cascades and Knickerbrook spike loads; do not run the car soft
Kerb use at the chicanes hammers sidewalls and inner shoulders
Cambered corners load the outside tyre harder than flat maps suggest
A 992 GT3 on Cup 2 R at Oulton Park International
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.
