Hi.
Our Plus 4 had many months ‘mothballed’, with an initial period on overly inflated tyres (35lbs I think, whereas usually 23lbs for normal driving). After that, up on jack stands with wheels off the ground. During the earlier period with higher tyre pressures, I went for a drive and you can see the effect of this in my Movie and Video forum ‘thread’ ... around about page 3 and headed, Greasy roads and Oversteer. So don’t forget to adjust pressures back to where they should be.
