These figures are for guidance only as no firm rules exist on optimum tyre pressures, they vary with driver, car and circuit.
As a general rule, if the car has understeer the front pressures should be increased, if the rear of the car is over steering the rear pressures should be increased.
Note: Because the Blockley tyre is a road tyre and has a stiff sidewall the tyre pressures are lower than used in a Dunlop race tyre.
