Tyre pressures at Bedford Autodrome GT
The venue as mapped, to scale. Bedford Autodrome GT is one of 3 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 Bedford Autodrome GT 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.
What Bedford Autodrome GT asks of a tyre
Bedford Autodrome was built as a driver training venue on a flat former airfield: enormous run-off, forgiving kerbs, a smooth surface and no walls. That same character makes it gentle on tyres, and the GT circuit's long lap has genuine straights, so tread temperature can be genuinely hard to build on cool days.
Low kerbs and smooth tarmac flatter pressures; the window still matters
Long lap with rest sections: expect lower hot deltas than at busier circuits
On cold mornings the tyres may never reach a semi-slick's window; plan for it

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.
