Rear tyres wearing on the insides

[Scottish Storm]

Given that the rear suspension doesn't appear to be adjustable, what would cause the inner edges off the rear tyres to wear?

The car was lowered to within an inch of its life until this weekend but given the simple axle design I reckon that would still keep the tyres fairly perpendicular- any ideas anyone?

As you lower the ride height the tyres will lean in more..... Therefore giving more negative camber.

That's probably the reason your tyres have worn more on the inner edges.

Camber isn't adjustable on the rear on the oem set up... You can however buy camber shims

That's what I initially thought but it's a simple pivot on the rear and both sides are solidly connected so I can't see how they can do more than just go straight up and down :-[

Have you checked the rear wheel bearings for play ?

Are they worn or not correctly tightened up ?

That might be a reason for the tyre wear.

as jreedy said when you lower the car with axel rear beam or independent suspension u will create more negative camber and also bring the wheels forward slightly causing the tracking to be all over the shop. you can buy kits to get the rear wheels sitting central again too. how long before you go through a set of tyres? also do you carry passengers often or have a weight in the boot. that can do it as well.

I just picked the car up a wee while ago and it was slammed to the ground. Tyres were advised at the mot a couple of months ago but more I've put standard suspension back on it I'll replace the tires next month and that should be it.

Scottish Storm, I'd reckon that you are correct, ie the rear end is just a solid beam that can twist but it pivots at both ends via the cranked ends. What I think has happened is this, these tyres have been on the front until they got into this condition, so the previous owner swopped them over. Lowered suspension must lead to the fronts suffering as the fronts will change camber when the spring length is changed.

That makes some sense. I'll be changing them soon anyway and I'll keep an eye to see if it happens again.
Thanks
