DRIVING AND OPERATING 181V-Series Vehicles Equipped withthe Original Equipment TiresFollow the requirements andrecommendations for tire inflationpressures while driving on varioustypes of tracks/courses. This helps toachieve a well-balanced vehicle andenhance tire traction performance.Use good judgment to determine theappropriate tire inflation pressure andspeeds for the track/courseconfiguration and environmentalconditions. Contact the tiremanufacturer if further assistance isneeded.To maximize tire life, drive 800 km(500 mi) prior to racetrack driving orcomplete the minimum track runningthat will increase the tire pressures by35 kPa (5 psi). After this, immediatelylet the tires cool to cold pressures.Tire Inflation PressureGuidelinesTire inflation pressures affect vehiclehandling and tire life, and should beadjusted for various types of tracks/courses.Inspect the tires prior to every track/course session. Track/course drivingwill reduce the tire tread life.Driving and Operating{ WarningOperating the vehicle at high speedscan be dangerous. Improper tireinflation pressure can putadditional strain on the tires andcan cause a sudden failure. Makesure the tires are in excellentcondition, and use the correct coldtire inflation pressure for thevehicle load and track/course.{ WarningTracks/courses put high loads ontires operating at high speed, whichcan lead to tire failure if notinflated properly. Always limitvehicle cargo to the driver plus onepassenger with no additional cargo.{ WarningTrack/course loads wear tires bothon the tread and internal to thetire. When driven in track/courseconditions, even if tread is not worndown to the treadwear indicator,tires must be replaced after theequivalent of two tanks of fuel orapproximately 160 km (100 mi).Tire Inflation Pressure for Trackswith Sustained High-SpeedOperation on Banked Turns(e.g., Daytona International Speedway,Indianapolis Motor Speedway,or similar)Inflate tires to a minimum of 300 kPa(44 psi) when cold.Do not reduce tire inflation pressurewhen hot.Tire Inflation Pressure for Trackswith Combined High-Speed andHigh-Load Corners(e.g., Nurburgring Nordschliefe, SpaFrancorchamps, or similar)
