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.

CORNERRUNS 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.

OSM — the sections mappers have named on this venue's tarmac: Island Bend · Island Hairpin · Foster's · Hilltop · Shell Oils Corner · Britten's · Hislop's · Lakeside · Cascades · Knickerbrook · Clay Hill · Old Hall Corner · The Avenue · Denton's · Lodge Corner · Deer Leap · Druids Corner · Warwick Bridge · Water Tower

Lengths are measured from the OpenStreetMap geometry drawn above, on the loop verified against this layout’s published lap length; 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.

FROM THE TYRE'S SEAT

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.

W1 Watch

Old Hall's long entry loads the left front every few tens of seconds

W2 Watch

Little rest per lap: expect higher hot readings than the ambient suggests

W3 Watch

Compression at Cascades punishes an underinflated left side

WORKED EXAMPLE · COMPUTED BY THE ENGINE

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.
