2009 C5 1.6 Hdi Vtr+ Tyre Wear/tracking Issue

[DropThePuck]

Hello,

 

I have had an ongoing issue with excessive tyre wear so was wondering if anyone had any thoughts.

 

I have a 2009 C5 VTR+ which has 215/60/16/H tyres which seem to wear out quickly, particularly on the passenger side.  I have had numerous tracking adjustments made and finally  had a computerised 4 wheel tracking check done (as attached), which the garage suggested I take to Citroen, which I did.  I was surprised when Citroen were happy with the results and the only suggestion they had was to put on the suggested tyre for this car - Michelin Energy Saver Tyres.  I currently have Pirelli's on the front, Goodyears on the back and don't see what difference having Michelins would make.

 

So, if there are any tracking guru's out there, I would appreciate your help.  The car has not been in an accident and I know some of the adjustments cannot be made.

 

Many thanks, in advance, for any assistance.

The following are from the Citroen manual, they do not mean anything to me but may be of use:

 

Front:

 

Checking values (Tyre dimensions : 215/60 R 16 ; 225/60 R 16)

Camber (not adjustable) -0°20' ± 0°30' 

Castor (not adjustable) 5°30' ± 0°30' 

Pivot angle (not adjustable) 8°12' ± 0°30' 

Tracking at the axle (adjustable) -0°09' ± 0°09'

Camber dissymmetry : + 0°50' / - 0°24'

Castor dissymmetry : ± 0°30'

Pivot angle dissymmetry : ± 0°30'

Distribute the global parallelism value symmetrically, left wheel-right wheel.

 

Rear:

Checking values (Tyre dimensions : 215/60 R 16 ; 225/60 R 16 ; 225/55 R 17 ; 245/45 R 18 ; 245/40 R 19) Camber (not adjustable) -1°56' ± 0°30'

Thrust angle 0° ± 0°30'

Tracking at the axle (adjustable) 0°43' ± 0°09'

Camber dissymmetry : ± 0° 30'

 

 

You could see if your tyre pressure gauge is accurate and then check if any of the brakes are binding by jacking each wheel and spinning them. Also check the track rod ends have been equally adjusted so the threaded rod part into the ends are the same length. Years ago, I have had new tyres fitted that had different tread patterns to before and the car has pulled to one side, so it is possible tyre choice could have an effect. If it pulls to one side the front strut top bearings could also be worth a look. There is also wheel bearing play/wear, and the list could go on. From previous experiences, if I thought I needed any tracking adjustments I would prefer to go to a dealer or garage rather than a tyre fitting place.

Thank you. That is really useful.  As you say not very meaningful to us, but at least I have something to take to my friendly mechanic who will understand it.
