Tyre pressures at Snetterton 200

The Snetterton 200 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 Snetterton 200 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.

Snetterton 200, on paper

OSM — the sections mappers have named on this venue's tarmac: Bomb Hole · Coram · Bentley Straight · Riches · Murrays · Montreal · Senna Straight · Brundle · Firmans · Agostini · Hamilton · Nelson · Oggies · Palmer · Williams

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 Snetterton 200 asks of a tyre

Snetterton 200 measures 3.17 km on the map, run clockwise, with 7 corners counted along that line, 5 of them right-handers. Corners come about every 452 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. Its longest straight runs about 865 m, far enough to cool the tread before the stop at the end of it, so a hot pressure taken in the pit lane understates what the tyre saw mid-lap.

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 200 layout cuts the lap short after Agostini and rejoins before Coram, trading the second straight for a tighter, busier rhythm. Less cooling time than the 300 means temperatures sit higher for the same driving, and the braking-heavy character remains.

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.
