Tyre pressures at Oulton Park Fosters

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 Fosters 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 Oulton Park Fosters asks of a tyre
The Fosters layout is Oulton's short club circuit, turning before the island section. It is a sprint lap of the venue's biggest characters: Old Hall, Cascades, the lake section. Short and physical, it keeps tyres in their working range with ease and rewards a stable, well-pressured front end at Old Hall lap after lap.
Old Hall's long entry loads the left front every few tens of seconds
Little rest per lap: expect higher hot readings than the ambient suggests
Compression at Cascades punishes an underinflated left side
A 992 GT3 on Cup 2 R at Oulton Park Fosters
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.
