Sports Driving Glossary: Tire Pressure - Sports Cars
Su roadThe correct inflation of the rubber (tires if we want to be picky) is very important for safety. A flat tire means more wear, more fuel consumption and a greater risk of aquaplaning in rainy weather. The latter case occurs due to the fact that a flat tire leaves more marks on the ground (it deforms, it tilts) and does not allow water to flow well, creating the effect of a rubber boat that plows the lake.
But let's go racing tiresor rather the tire pressure. A racing tire (almost always smooth except in rare cases) is very different from a road tire. Composition, carcass, structure are changing: everything is aimed at maximum performance.
It is the smooth tires that make them unmatched on dry asphalt, but very dangerous on wet, because there are no grooves (or notches) to drain the water.
Temperature
THE bus the races also need to be warmed up before you can push the car to the limit. When cold, they look like ice and only work well at high temperatures in a fairly small window.
The best way to warm them up it is during braking that they heat the discs well, which, in turn, heat the rim and, accordingly, the inner part of the tire.
La pressure it increases because the air inside it heats up and expands. Zig-zag movements to warm up the rubber often do more damage than anything else, as it only risks ruining the carcass.
The pressure ranges from 2.4 / 3.15 bar, and the difference between front and rear varies depending on the ratio / position of the engine.
New tire
When you install new tires, you have limited time to take advantage of productivity. In qualifications, this translates as 2/3 full laps when the tire is fresh and running at maximum performance, after which its performance will drop and stabilize for a few laps (or kilometers, if you prefer) until it is completely worn out.
Il experienced pilot he can change them according to his preferences and how he “feels the car”. There pressure More precisely, it needs to be modified in “blocks” of 0.15 bar, and you can play with the pressure difference to increase the understeer or oversteer of the car.
