Tracking & Camber

I test for correct ? inflation by feeling the temperature of the tread after  few dozen miles on dry roads ( not ragging it ) & judge them to be O.K if pleasantly warm.

But that could all vary with tyre compound, I suppose.

Should have read higher up.

The only car I ever ran pressures like that was my 2 tonne Galaxy with 6 up in full holiday mode

20psi more like it

did that make a noticeable difference?

Not sure yet mate I haven't been out in the wet since, sounds very like it could do tho!
