Tyre pressures at Barcelona Catalunya 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 Barcelona Catalunya 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.

What Barcelona Catalunya GP asks of a tyre
Barcelona is the classic test track for a reason: the long right of Turn 3 and the Campsa sweep put sustained energy through the left front on an abrasive surface, and the final sector's slow corners then demand traction. It is one of Europe's harder circuits on front tyres, and it rewards exactly the measurement discipline this method teaches.
Turn 3 is a left-front endurance event; probe its outer zone first
Abrasive surface builds temperature and wear together
The slow final sector works the rears on traction; check the split both ends

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.
