Tyre pressures at Snetterton 300
The venue as mapped, to scale. Snetterton 300 is one of 2 layouts sharing this tarmac, and its exact course differs from the full-circuit outline shown. 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 300 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 | +1.5 |
| Right front | +1.0 |
| Left rear | +2.5 |
| Right rear | +2.0 |
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.
What Snetterton 300 asks of a tyre
Snetterton 300 pairs two long straights, the Bentley and the Senna, with proper stops at Brundle, Agostini and Murrays, plus the fast Coram sweep feeding the final chicane. Straights cool the tread and the big braking zones heat the fronts, so the tyre's lap is a cycle of recovery and punishment rather than constant load.
Heavy braking zones push front temperatures and pressures up
Coram's long right leans on the left front late in the lap
Long straights mask true tread temperature; probe immediately on returning
A 992 GT3 on Cup 2 R at Snetterton 300
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 / 21.6 front, 22.6 / 22.7 rear. A different car, tyre or morning moves every number, which is what the calculator is for.
