Hi all, fitted four new Michelin Primacy HP tyres (225/55/16W) to my 2004 W211 E320 Cdi Yesterday.
Reason - N/S front had worn right through on the inner & outer edges & lost air. The O/S front wasn't much better. Rears were down to a couple of mm. The old tyres were Primacy HP's as well.
The tyre guys said (and I'm absoluteley sure they're correct) that this was due to under inflation. I've been following the manual and been giving the fronts 29 Psi and the rears 30 Psi (Which were undamaged). The garages charts tell them that this is correct for my car & these tyres.
I know that my 2 tyre gauges at home are accurate as they've been checked against the garage's gauges.
We've gone up to 32 Psi all round to see if we fare any better.
Has anyone had this problem before? These 4 tyres cost an arm & a leg so I dont want them going the same way! What pressures do you put in yours?
Any advice would be most appreciated.
Cheers..................Joker.
