Tyre pressures at Silverstone International
The Silverstone International 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 Silverstone International 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.
| CORNER | RUNS HOTTER BY, °C |
|---|---|
| Left front | +2.0 |
| Right front | +1.5 |
| Left rear | +3.0 |
| Right rear | +2.5 |
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.
Silverstone International, on paper

OSM — the sections mappers have named on this venue's tarmac: National Pit Straight · Hamilton Straight · Club · Brooklands · Wellington Straight · Luffield · Copse · Woodcote · Chapel Curve · Maggotts · Hangar Straight · Aintree · Farm Curve · The Loop · Stowe · Vale · Village · Abbey · Ice Hill · Kick Plate · Becketts · Limestone Curves
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 Silverstone International asks of a tyre
The International layout uses the Grand Prix circuit's southern half, keeping Becketts' high-speed direction changes and the Hangar straight. It drives like a condensed GP lap: big lateral energy through the complex, then genuine cooling time down the straight before the Stowe braking zone.
Becketts loads both fronts in quick succession; compare left and right averages
The straight cools the tread; expect inner zones to read cooler than the lap feels
Stowe's braking zone works the fronts on top of their cornering load

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.
