Tyre pressures at Donington Park GP

The Donington Park GP 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 Donington Park GP 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.

Donington Park GP, on paper

OSM — the sections mappers have named on this venue's tarmac: Roberts · Fogarty's · Wheatcroft Straight · Old Hairpin · Goddards · Redgate · McLeans · Coppice · Melbourne Loop (up) · Melbourne Hairpin · Starkey's Bridge · Hollywood · Craner Curves · Melbourne Loop (down)

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 Donington Park GP asks of a tyre

Donington Park GP measures 3.99 km on the map, run clockwise, with 12 corners counted along that line — 5 left, 7 right. A corner every 333 m gives the tyre a steady rhythm of work, enough to build temperature without running away with it.

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.

Donington rewards momentum: the plunge through the Craner Curves and Old Hairpin is one of the great high-load sequences in UK track driving, working the outside of the car hard while the lap's rhythm keeps tread temperature up. The GP loop adds the Melbourne hairpin and a second heavy braking zone, so fronts get a workout the National layout spares them.

Published hot target 30.5 / 32.0 psi at 92°C tread, on a 15°C morning, with the corner figures above: cold set 21.5 / 21.5 front, 22.6 / 22.6 rear. A different car, tyre or morning moves every number, which is what the calculator is for.
