Endurance racing exposes tyres to prolonged heat, repeated abrasion, impacts and variable loads; effective telemetry can give teams advance warning of impending failure and reduce safety and strategic risks. Research on tyre dynamics by Hans B. Pacejka TNO and technical guidance from the Fédération Internationale de l'Automobile emphasize the importance of combining several correlated signals rather than relying on a single measurement.
Key telemetry signals
Continuous monitoring of tyre pressure and tyre temperature is foundational because changes in pressure alter carcass flex and heat build-up, while temperature gradients across the tread reveal localized overheating and delamination risk. Vertical load and lateral/longitudinal force telemetry identify operating envelopes where rubber and structure are stressed beyond design limits, and wheel speed and slip ratio detect prolonged skidding that accelerates wear. Rim and brake temperatures flag localized heat transfer that can preheat seals and inner liners, and high-frequency vibration or acoustic emissions often indicate emerging structural faults such as cord breakage or separation. Authors and institutions working in tyre modeling show that force–slip–temperature relationships are central to understanding failure mechanisms Hans B. Pacejka TNO.
Causes, predictive value and consequences
Tyre failure in endurance events typically follows mechanisms: progressive thermal degradation from sustained high surface temperature, structural fatigue from repeated high vertical load cycles, sudden impact damage from debris or kerbs, and underinflation-driven carcass flexing. Pressure and carcass temperature trends frequently provide the earliest actionable signals, but their predictive value improves markedly when fused with load and vibration data using statistical or machine-learning models. Industry practitioners at Michelin Motorsport describe integrated sensor suites as the operational standard for race safety and strategy.
Consequences extend beyond immediate driver safety to sporting outcomes, crew workload and environmental impact through increased tyre waste and hotter tracks in certain territories. Cultural practices such as aggressive stint lengths or regional circuits with wide day–night temperature swings, for example at Le Mans, change the interpretation of telemetry and require localized calibration of predictive models. Regulatory bodies including the Fédération Internationale de l'Automobile encourage transparent telemetry use to balance competitiveness and safety, underscoring that multi-parameter monitoring remains the most reliable approach to predicting and preventing tyre failure in endurance racing.
