Tyre pressures at Brands Hatch Indy
The venue as mapped, to scale. Brands Hatch Indy 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 Brands Hatch Indy 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 Brands Hatch Indy asks of a tyre
The Indy circuit is short, intense and almost all right-handers: Paddock Hill Bend's famous downhill compression, Druids hairpin, Graham Hill, Clearways. Laps come around quickly and the left side barely rests. Heat builds fast even in winter, and overpressure by the session's end is the classic Indy mistake.
Left-side temperatures dominate; set the split accordingly and verify with the probe

Short lap, big traffic: cool-down laps are rare, so bleed hot pressures between sessions

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.
