Track day tyres: pressures, types and what to know before riding

Tyres are the element that changes most between road and track riding. Working temperature, optimal pressures, and compound type are all completely different, and using road settings on track can reduce grip and increase risk. ## Why tyres behave differently on track On track, tyres work harder: higher temperatures, more G-force in corners, more wear per lap. A tyre that has not reached its optimal working temperature does not provide the grip it should, leading to misleading sensations at the start and unexpected grip loss exactly when you need it most. ## Cold pressure vs hot pressure Working pressure on track is usually different from road pressure. The right numbers depend on the bike, tyre model, ambient temperature, and compound. As a general starting point: - Hypersport tyres typically work on track between 1.9 and 2.3 bar hot at the rear. - Cold pressures set before going on track are lower because they will rise as the tyre heats up. - Never use the manufacturer's road pressures as a direct track reference without checking first. Always ask the tyre service on site or the organizer: they know the conditions for that specific day. ## Tyre types for track use - Sport touring / GT: Not recommended for regular track use. They can work for low-intensity beginner days but rarely reach optimal working temperature. - Hypersport / sport: The most common choice for track days. Michelin Power RS, Pirelli Supercorsa SP, Bridgestone Battlax RS11 are familiar references. Good balance between durability and grip. - Slicks and semi-slicks: For experienced riders looking for maximum grip. They require controlled temperature with warmers, technical knowledge, and circuits in good condition. ## Tyre warmers: what are they for? Warmers keep tyres at working temperature before going on track. They are useful on cold days, in short intervals between sessions, and with high-performance tyres. For a beginner or intermediate rider on hypersport tyres, warmers are convenient but not essential if you take the first laps carefully. ## When to replace tyres - Wear indicators at the limit. - Uneven wear: flat spots, centre squaring, sharp edges on the shoulders. - After a crash that may have damaged the internal structure. - Old tyres with remaining tread depth, as the compound may have degraded over time. ## Before going on track Visually inspect the tyre before each session. Check cold pressures against the day's recommendations. Take the first laps with margin until the tyre has reached temperature. If something does not feel right, return to the pits and ask. Check available track days on Track Demons and always arrive with your tyres in proper condition.
