Michelin Pilot Sport GT M Race & Autocross Tires in 31/71-18

The Pilot Sport GT M is Michelin's Racetrack and Autocross Only tire developed for a wide variety of vehicles looking for maximum performance to match their race-ready vehicles. They're built to deliver stable dry handling, repeatable lap performance, high grip levels, and the durability required for prolonged race events.

The Pilot Sport GT M is constructed with a high-friction racing compound engineered to optimize traction through prolonged racing sessions. Michelin's Track Longevity 2.0 helps preserve compound integrity under heat and sustained mechanical load during extended sessions, while reinforced shoulder architecture minimizes wear during aggressive cornering. Dynamic Response technology integrates aramid and nylon materials in a hybrid reinforcement layer to enhance steering precision by optimizing force distribution across the contact patch. Integrated tread wear indicators on the tire surface allow for rapid visual assessment of remaining treadlife.

Available in S7, S8 and S9 compounds to support a multitude of race events in different locales or ambient conditions.

If you use a heater cabinet or tire warmers: the maximum heating temperature must not exceed the internal rolling temperature of the tires.

Above this temperature, the properties of the rubber can change and thus degrade performance.

The minimum warm-up time is 45 minutes to reach stabilization. The maximum heating time is 2 hours (beyond this, there is a risk of the rubber changing).

Michelin Pilot Sport GT M tires do not meet DOT requirements, and are not appropriate for roadway use. Michelin Pilot Sport GT M tires are not intended for driving in wet conditions where standing water is present and there is the risk of hydroplaning; drivers should drive cautiously at reduced speeds if they encounter these conditions. Like all Racetrack & Autocross Only tires, Pilot Sport GT M tires are not intended to be driven in near-freezing temperatures, through snow or on ice. It's essential these tires be stored indoors according to Michelin recommendations.

During storage and transport, the temperature must be higher than:

On Storage: Tires must not be subject to:

• Direct and prolonged exposure to sunlight
• Sources of extreme heat and humidity
• Solvents, lubricants, fuels and other chemicals
• Ozone emissions from equipment such as a transformer, welder, electric motor, etc.
• Long-term storage in a stack.

Non-compliance with these storage recommendations may significantly reduce the period over which the tire retains its performance. The storage location must be dry, ventilated, out of direct light and kept solely for tires. Racks allowing tires to be stored vertically are to be used in order to avoid tension on the casings.

Note on Tire Aging: Michelin recommends using Michelin Competition tires within a maximum of 24 months following their date of purchase (within 4 months in the event of storage in severe tropical- type conditions) or within 12 months for wet tires.

Los neumáticos de uso especial: Solo Para Pista y Autocross En Seco, poseen una banda de rodamiento con diseño liso y un compuesto de caucho optimizado, para obtener tracción sobre superficies secas. Estas características, proporcionan el mejor desempeño del neumático en aceleración, frenado y al tomar curvas. No deben ser utilizados en carreteras o exponerlos a temperaturas cercas al punto de congelación*.

*Algunos neumáticos pueden ser utilizados con una profundidad de 6/32" (4.8mm) en condiciones mojadas y requieren afeitarse a una profundidad de 4/32" (3.2mm) para condiciones secas.
