Why are weather forecasting and track temperature important when preparing for a practice session?

• A. Forecasting informs tire choice and setup
• B. Track temperature affects grip and tire wear
• C. Both forecasting and temperature are important
• D. They have no effect

Answer: (C)

The main idea here is that tire grip and setup depend on both predicted weather and the track’s current temperature. Forecasting guides which tire compound to use and how you’ll set the car for the session. If rain is predicted, you’d plan for wet or intermediate tires and adjust pressure, suspension, and aero to maximize contact with the surface. If temperatures are expected to be very high or very low, you choose tires and set them up to reach and stay in their optimal operating range, avoiding overheating or stalling grip.

Track temperature directly influences grip and tire wear. A warm track lets tires reach their ideal rubber temperature quickly, giving more grip but also elevating wear if you push hard. A cool track means less grip and slower heat-up, so you might start with a different pressure or camber and build up temperature gradually. Too hot a track can overheat tires, degrading grip and increasing wear, while a too-cold track can leave you under-tyred and slower.

Using both factors together gives the most reliable preparation: you anticipate how grip will behave and how the tires will age during the session, allowing you to choose the right tire and set the car to maintain consistent performance.
