Tyre pressures at Circuit of the Americas
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 Circuit of the Americas 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 | +2.0 |
| Left rear | +2.5 |
| Right rear | +3.0 |
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 Circuit of the Americas asks of a tyre
The Circuit of the Americas runs anticlockwise with a first sector of fast esses modelled on the great direction-change sequences, cycling the car left-right at speed, and Texas heat that can push track temperature far beyond ambient. It is known as a demanding circuit for tyre energy: the esses load both sides in quick succession and the long back straight then cools everything.
The esses cycle both fronts hard; compare left and right zone averages
Texan track temperatures run far above ambient; recompute at midday
Anticlockwise overall: expect the right side warmer across a session
A 992 GT3 on Cup 2 R at Circuit of the Americas
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.
