If you car's front tyres loose adhesion because they are over pressured and it carries straight on when you turn the steering wheel, isn't that understeer? Or am I missing something?
Sorry have I missed something? The steering is much more positive on turn in with the higher pressure, I understand that understeer / oversteer can be effected by increasing / reducing tyre pressures on one axle, I have increased all pressures, so the balance remains the same (as far as I understand).
