Formula 1 cars are engineered to shave milliseconds disconnected thigh times, truthful it's nary astonishment that moreover tires get nan red-carpet curen done nan usage of tyre blankets. Those weird quilted covers you spot wrapped astir each group of Pirellis connected nan grid aren't conscionable for show, however. They're power guns successful disguise, and they're important to making judge cars don't tiptoe retired of nan pits for illustration babe cervid connected ice.
While Pirelli useful connected making nan high-performance F1 tires much sustainable, their capacity criteria stay nan aforesaid and these tires conscionable don't for illustration nan cold. Tire blankets preheat nan rubber to a moving somesthesia earlier it ever hits nan track. In F1, that intends heating rear tiers to location astir 158°F (70°C) for a mates of hours earlier a title starts and nan cars exit nan pits.
After all, acold tires are slippery tires, and successful a athletics wherever grip equals thigh time, sending a car retired connected stone-cold rubber is for illustration F1 but connected an crystal skating rink. You're going to suffer grip, and astir apt a fewer beforehand wings. So it turns retired that preheating nan tires isn't conscionable astir capacity — it's a important information measure.
Why F1 can't usage acold rubber

The full constituent of a tyre successful racing is to supply grip, and grip is simply a temperature-dependent thing. The conception is elemental — rubber erstwhile acold is brittle and rigid while higher temperatures make it much flexible. The much elasticity a tyre has, nan much interaction it makes pinch nan way arsenic it deforms astir nan grooves of nan surface. The rubber compound connected F1 tires is designed to run optimally astatine astir 212°F (100°C). This is why you spot drivers weaving astir to get nan tyre temperatures up during nan statement lap.
Tire blankets thief get tires into that optimal scope faster. Warmer tires make much grip and frankincense supply amended performance. When a car exits nan pit lane connected preheated rubber, nan driver tin push sooner and debar a sketchy first-lap slide-fest that tin hap pinch acold tires. Without blankets, drivers would person to walk much laps bringing tires up to temp.
For 2024, F1 was flirting pinch nan thought of banning tyre blankets successful nan sanction of sustainability, but aft testing and feedback from teams, that norm alteration sewage bumped to astatine slightest 2025. Reigning World Champion Max Verstappen raised concerns astir information and tyre deterioration if they had to lukewarm tires purely done driving. In fact, tires are truthful important that Pirelli collects them backmost aft a title play to measure them.
Not your grandma's heating pad

Tire blankets aren't conscionable fancy covers, they're high-tech power wraps stuffed pinch heating coils and thermally conductive gel. Once plugged in, they clasp temps for illustration a champ, keeping that slick rubber lukewarm and fresh to grip nan 2nd it hits nan tarmac.
Each tyre broad wraps snug astir nan full wheel, locking successful power crossed each inch of rubber. Once each 4 are fitted, they're wired up to a power container that acts for illustration a pit lane thermostat, cautiously managing nan temp buildup. Of course, location are rules and F1 takes them very seriously. Slicks tin only beryllium preheated for 2 hours, max, astatine 158°F (70°C). Intermediates get nan aforesaid clip limit but headdress retired astatine 140°F (60°C). As for afloat wets? No broad clip astatine all. If it's raining, you're going retired cold. Pirelli did present caller bedewed upwind tires that came into effect successful 2023, but they don't request heated blankets.
F1 multi-colored tyre compounds are analyzable components and yes, tyre blankets connected them whitethorn look for illustration glorified electrical duvets, but they're conscionable arsenic captious to capacity and information successful F1. They guarantee cars motorboat retired of pit boxes pinch assurance and control, fresh to grip and rip astatine afloat tilt.
