Hiya,

Carolyn's Superb has been on for a service and they noticed that the rear tyres are wearing a bit on the inner edges (We are running Audi BBS A8 split rims 18"). Anyway took it for a proper 4 wheel alignment session and it looks like only the front was slightly out. Could this cause the rears to wear or do we have another problem??

Cheers

Hmm.

Certainly inner edge wear points to camber problems, but the four wheel alignment showed nothing... a head scratcher for sure.

Still, perhaps it could have something to do with camber and the alignment place missed it? Ne fule no that all tracking systems/garages/etc are different... or are they?

Short of that, perhaps it's got something to do with the split rim?

Let us know how you get on anyway

IMHO, you cannot adjust camber in rear as its rigid axle. You can affect on toe indirectly by making sure that rear axle is not crooked, your 4-wheel-aligment report should tell this. If it's not straight it could be possible to turn it slightly with crowbar by loosening rear axle bolts.

:eek::eek:

Mine does the outside of the rears and eats front ones, it's the car, I've had it all checked and there's nowt wrong, and further proof I can go down the motorway and remove hands for a few seconds and there's no drift, so I blame it on soft suspension and heavy body.

not a lot of help I know, but my rears wear evenly and still plenty there - about half worn at 35k miles (at least on the original one that wasn't replaced when punctured!)

could it be related to the wheels - rim width, offset..?

do you tow, carry heavy loads?

cheers

, carry heavy loads?

cheers

You could put it that way

Forgot to ask is the car lowered? What pressures you're using in tyres?

- just sounds a bit dramatic and hit & miss. At least to those of us who do little more than check the oil!

Well, of course this must be done while car on ramp and 4-wheel-alignment gear hooked up. Then mechanic sees immediately where its going, if anywhere. It might move or not depending if there's any room around bolts. I'm not sure if this an "official" way to do rear axle aligment but definetely you/mechanic have a fair change to make it better, even within tolerances.
