How reliable is this recommendation based on your inputs:

  • Temperature — Extreme cold (<8°C) or heat (>38°C) makes pressure behaviour harder to predict.
  • Grip level — Developing or dusty surfaces are less predictable than a well-rubbered track.
  • Tyre wear — Heavily worn tyres have inconsistent carcass flex.
  • Altitude — Above 400m, gauge pressure correction is applied; above 1000m confidence decreases.
  • Humidity — Very high (>80%) or very low (<25%) humidity affects grip and tyre warm-up.

90%+ ideal conditions · 70–80% cross-check after warm-up · <70% rough starting point only.

Pressures are cold-start recommendations based on compound, grip level, altitude, humidity, and ambient temperature.
Always cross-check with your engineer and adjust by ±0.02 bar after the warm-up lap.
