Tyre pressures at Sebring International
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 Sebring International 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: Sunset Bend · Ullman Straight · Le Mans Curve · Gendebien Bend · Bishop Bend · Tower Turn · Cunningham Corner · Collier Curve · Hairpin · Fangio · Gurney Bend
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 Sebring International asks of a tyre
Sebring is the roughest famous surface in this database: much of the lap runs on original airfield concrete whose bumps and seams hammer the car and cycle tyre loads constantly. It is a test of compliance as much as grip, and pressures that are too high skip and scrub across the concrete instead of gripping it.
Bumps punish overinflation; err conservative and verify with the probe
Concrete sections read different temperatures to the asphalt ones; note where you probe
The hairpin and Sunset Bend work opposite ends of the car; check both splits
A 992 GT3 on Cup 2 R at Sebring International
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.
