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.

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.

Oulton Park Fosters, on paper

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.

What Oulton Park Fosters asks of a tyre

Oulton Park Fosters measures 2.65 km on the map, run clockwise, with 7 corners counted along that line, 6 of them right-handers. Corners come about every 379 m, so the lap is more about carrying speed between them than surviving them back to back. With the corners weighted that way the left-hand tyres do the work and barely rest: expect them hotter and higher in pressure than the right, and read the two sides separately rather than as an axle.

DERIVED — length, corner count, hands and straight measured from the mapped lap drawn above. Corner counting is a judgement (a double apex can be read as one corner or two), so treat these as this line's reading of the circuit, not a series' official figures.

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.

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.
