Tyre pressures at Cadwell Park Full

The Cadwell Park Full loop, drawn bold on the venue's mapped tarmac; the loop's measured length agrees with the layout's published lap length. 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 Cadwell Park Full 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.

Cadwell Park Full, on paper

OSM — the sections mappers have named on this venue's tarmac: Club Hairpin · Barn · Charlies · Chris Curve · Coppice · Hall Bends · Mansfield · Park Straight · Park · The Gooseneck · The Hairpin · The Mountain

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 Cadwell Park Full asks of a tyre

Cadwell Park Full measures 3.45 km on the map, run clockwise, with 16 corners counted along that line — 7 left, 9 right. That is a corner every 215 m, so the tread is asked for something almost continuously: heat arrives early and keeps arriving, and pressures climb through a session faster than the morning's ambient reading suggests. Nothing on the lap is straight for longer than about 396 m, so there is no stretch where the tread gets a real chance to cool.

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.

Cadwell Park is narrow, wildly undulating and utterly absorbing: the Mountain section lifts wheels, Charlies and the Gooseneck demand precision, and there is almost nowhere to rest. Loads cycle vertically as much as laterally. The tight, technical pace means tread temperature builds from work rate rather than outright speed.

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.
