Tyre pressures at Watkins Glen GP
The lap, to scale. 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 Watkins Glen GP 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.

OSM — the sections mappers have named on this venue's tarmac: Watkins Glen International · Outer Loop · Short Course · The Esses · The Fast Lefthander · The Heel · The Ninety · The Boot · The Toe · The Chute · Inner Loop
Lengths are measured from the OpenStreetMap geometry drawn above; 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 Watkins Glen GP asks of a tyre
Watkins Glen is fast, old-school America: the uphill Esses onto the back straight, the Bus Stop chicane, and sustained speed through the boot. Vertical gradient and high commitment corners put real energy through the tyres, and the fast rhythm keeps them working all lap.
The uphill Esses load the car compressively as well as laterally
Bus Stop kerbs strike hard at speed; sensible pressures protect the shoulders
High average speed brings strong pressure rise; bleed to target hot
A 992 GT3 on Cup 2 R at Watkins Glen GP
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.
