re: FWD excessive tire wear

["David Hanley" <david.hanley1@domain.elided>]

Tess,

New Tires 12 months ago, and wheels aligned at that time.

16k miles covered since.

Front tires only effected, wear is inside only, like someone has took a
knife to the tires at a 45 degree angle, and cut the inside corner off,
all round.

Can't see any interference being possible with any body parts, or any
rubbing marks on any parts around.

 

Car is a 166 3.0V6, effectively a 164 with not so pretty body. I had 164
previously.

 

Car has got twitchy in last 2 weeks or so, so I knew something was up,
and I took it to get a MOT (annual UK safety) test today.

Wire is starting to show through on inside edges of tires - test failed.
Need new tires to pass, otherwise I can't drive it on UK roads!

 

Bears slightly to left under heaving braking. Jumps a bit around
corners. Lovely Alfa direct feel, but now a bit twitchy.

Suspension is stock.

Ticking noise coming from engine when stood still has also developed
recently - fuel injectors I think.

 

Can you explain more about the camber problems ? and the wear it would
cause ?

 

Thanks and Regards

David.
