Chassis Setup and Troubleshooting

Troubleshooting Tire Temps

Center hotter than edgesTire pressure too high.
Reduce 1 psi (0,07bar) for each 5° F (2,75° C) delta
Edges hotter than centerTire pressure too low.
Add 1 psi (0,07bar) for each 5° F (2,75° C) delta
Inner edge hotter than outerToo much negative camber
Outer edge hotter than innerNot enough negative camber or too much toe-in
Tire below ideal temperature rangeTire pressure too high or Tire too wide or Springs/sway bars too soft at that axle
Tire above ideal temperature rangeTire pressure too low or Tire too narrow or Springs/sway bars too stiff at that axle
Front tires hotter than rearCar is under steering (pushing)
or Too much front spring/sway bar
or Not enough rear spring/sway bar
or Front pressure too low
or Rear pressure too high
or Front tires too narrow
or Rear tires too wide
Rear tires hotter than frontCar is over steering (loose)
or Too much rear spring/sway bar
or Not enough front spring/sway bar
or Rear pressure too low
or Front pressure too high
or Rear tires too narrow
or Front tires too wide

A 1 Celsius change is a change of 1.8 Fahrenheits while a 1 Fahrenheit change translates to a change of 0.55 Celsius.This is one of the easiest way to convert them if you know that 0°C = 32°F

Correcting Over- or Understeer

Reduce Oversteer
Reduce rear pressures or increase front pressures
Increase Oversteer
Increase rear pressures or reduce front pressures
Reduce Understeer
Reduce front pressures or increase rear pressures
Increase UndersteerIncrease front pressures or reduce rear pressures
