RENNSPORT: tyres overheating — what to change
What it feels like
Grip falls off after two or three laps and temperature or pressure climbs past the window.
Why it happens and what we're after
Overheating tyres: lower pressures to reduce core tyre temperature.
What to change, exactly
Ranges, steps and defaults are the REAL ones for this sim. The amount is expressed in the game's own unit so you can apply it without converting anything.
Parameters flagged as “estimated range” do not come from a verified in-game capture: the direction of the change is right, the exact magnitude may differ on your car.
1.Front tyre pressure
Lower ↓ by 0.20 bar4 slider stepsestimated rangeRange: 1.80 – 2.90 bar · Default: 2.50 bar
Cold front tyre pressure (bar). NOTE: RENNSPORT's own developers confirmed a known calibration mismatch — the number you see on screen (e.g. 2.50 bar) does NOT behave like a real 2.50 bar, closer to ~1.7/1.8 bar on a real car (source: rennsport.gg, Beta 1.8.3 patch notes; unconfirmed whether this has since been fixed). Treat the number as a game-relative reference, not a 1:1 physical pressure. (unit confirmed, range estimated)
What changes when you move it this way
More contact patch and mechanical grip, but vaguer response and risk of overheating from flex.
2.Rear tyre pressure
Lower ↓ by 0.20 bar4 slider stepsestimated rangeRange: 1.80 – 2.90 bar · Default: 2.50 bar
Same as front but on the rear axle: affects traction and rear stability. Same calibration caveat as the front (see above). (unit confirmed, range estimated)
What changes when you move it this way
More traction and rear stability, until pressure drops so low it overheats.
How to apply it without losing your afternoon
- 01Change ONE thing at a time and run three clean laps before judging. Two changes at once and you no longer know which one worked.
- 02Start with the first parameter on the list: they are in the order the engine applies them, from the one with most authority to the fine tuning.
- 03If the change goes the right way but falls short, repeat the same step again before touching another parameter.
- 04If it gets worse, put it back. A setup you don't understand is slower than a baseline you do.
Where this sim stores its setups
No verified in-game file-based setup import/export system was found for RENNSPORT (unlike ACC/iRacing/rFactor2 in this catalogue). The game lets you save named setups inside the garage, but the research behind this PR did not confirm an on-disk file location or exportable format.

If that wasn't it
Symptoms get confused with each other: what feels like poor traction is very often oversteer on throttle. These are the other diagnoses for this sim.
The same problem in other sims
Same symptom, different parameters: each game exposes different sliders, with other units and other ranges.
