1. Why is it that the Cossie runs more pressure on the rear tyres when more weight is in front?

2. When the rim/tyre size change, how much to increase pressure for an increase in size of 1" in rims and say 5mm (50 to 45) in height respectively?

3. How much to decrease when the tyres increase by 10mm (e.g. 205 to 215?)

As a guideline of course...

And by the way, please state, if possible what kind of pressure/camber/toe you guys are running on your tyres with the rim and tyre sizes stated and why.

Oh, and of course any great way to reduce the Cossie's understeer...

Cheers!
