Tyre pressures at Hungaroring

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 Hungaroring 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.

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.

Hungaroring, on paper

OSM — the sections mappers have named on this venue's tarmac: Hungaroring · Bokszutca

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 Hungaroring asks of a tyre

Hungaroring measures 5.43 km on the map, with 16 corners counted along that line. A corner every 340 m gives the tyre a steady rhythm of work, enough to build temperature without running away with it. Its longest straight runs about 794 m, far enough to cool the tread before the stop at the end of it, so a hot pressure taken in the pit lane understates what the tyre saw mid-lap.

DERIVED — length, corner count, hands and straight measured from the mapped lap drawn above. Corner counting is a judgement (a double apex can be read as one corner or two), so treat these as this line's reading of the circuit, not a series' official figures.

The Hungaroring is tight, twisty and often hot: a lap of near-constant steering where front tyres carry the workload and there is little straight-line rest. In summer heat the challenge is keeping the fronts inside the window, not reaching it, and the crown of the tread tells the pressure story quickly.

Published hot target 30.5 / 32.0 psi at 92°C tread, on a 15°C morning, with the corner figures above: cold set 21.4 / 21.4 front, 22.5 / 22.5 rear. A different car, tyre or morning moves every number, which is what the calculator is for.
