Tyre wear in rear inside edges

[lee gsi]

Is it the banana shape control arms giving me rear camber and wearing my rear tyres?

No, just the car design

catch hold of the rear tyre AT 12 O'clock and give it a tug, if its got movment it is the upper control arms/bushes, just gett ing some quotes to have mine done.

Rear upper control arms are worn, it's the only time any of my Vectras have ever scrubbed the inside edge on the rear.

Mine have never worn, sent a set of Good Year tyres for inspection in 2008 and they confirmed it was due to rear setup on Vectra C (which is correct)

If it's excessive wear then it's quite possible mate.

although make sure the car is on the ground as the weight needs to be on them

Very true, while the design of the rear suspension will lead to very slightly more wear on the inside edges it will be accelerated by knackered upper control arms

Tracking is affected by all components of the suspension effectively - worn suspension components are without doubt going to take their toll on the tyres one way or another.

One off eh? Neither have mine, but that doesn't mean it's not a reason for worn insides of the tyres in this case.

Mine used to eat rear tyres like hot cakes. I replaced the rear UCAs myself (not a bad job but some bolts fiddly to get to), had the alignment set up professionally and got new (budget) tyres. The car was transformed! It felt lighter, nimbler and more responsive, even despite the tyres being cheap Chinese ones.

The rear wheels still have some negative camber but it's set up that way for safety reasons.

If you do have a go yourself, be very careful not to drop any of the Torx bolts as you remove them! I dropped one inside one of the other rear suspension links and had to remove that one as well just to remove the bolt. That meant that I had to get the alignment done straight away because I had to remove the eccentric washer in the adjustable linkage. Not much fun, that part!

Most of my tyres go back to manufacturer for inspection, unless they are worn evenly down to the minimum perfectly

It was quite obvious on that set of Good Year tyres, as it was the only time I did not rotate them rear to front, as the fronts wore
They had 30K miles on the rear, instead of the normal 10K miles
Both inside edges were perfectly down to 0mm, 3mm on the outside edges, and 1.6mm across the central three quarters of the tread

Two other tyres went back earlier this year, Good Year confirmed both had failed due to manufacturing defects
Again, they commented the wear suggested it had been fitted to the rear, due to the wear pattern
I checked the tyre batch code, and indeed was the tyre that had been fitted to the rear

As always, on fitting new tyres, check the suspension, check the tyre pressures, then have a full four wheel alignment carried out
The rear tyres will still wear on the inside edges!

I prefer to go to a tyre fitter get the tyres changed when they have reached their legal tread life or if the weather has affected them prematurely. Most do that. Tracking gets done every 2/3 years. Tbh that's normal.
