Hi chaps as the post thread title. What typre pressure should I be on all round under normal driving and a couple of passengers?
Is it 31 PSi?
Tyres are 235 40 18 As standard on 18" RS6 style rims? Correct me!
Also noticed a little bit of jittering in the ride at speed? The clock reading 80Mph - first I thought it might be a nail or something?
