B8 A4 Tyre Pressures
Just joined forum so sorry for late reply.
I've been driving a 58' plate A4 3.0 TDI for 8 months around the roads in Aberdeenshire. It's still shed with the original 18" Bridgestones. After playing about with the tyre pressures (reducing/increasing/recommended values) I've come to the conclusion it's the steering/handling set up that's at fault, combined with the wheel size/tyre stiffness. This is on an A4 with the full drive select fitted. The car drives fine on smooth roads but as soon as any type of rutting exists it jumps about all over the place. I've even considered dropping down to 17" or 16" wheels to see if it improves things but I've still to bite the bullet and invest.
