Wear on inside edge of tyre
#1

I replaced the front brakes last week and noticed that on the nearside (left) front tyre there is a lot of wear on the inside edge, but not much on the other tyre. I had the tracking checked and it is almost spot on, certainly not enough to cause wear. Any suggestions as to what might be causing this?

if the camber is good on that corner and in, or very near spec, one of the suspension components (bushing) is allowing it to toe 'out' when driving; that's hard to diagnose when its on a lift, not moving. You've got to really put some force on the tire/wheel when setting the toe to introduce the same force as normal road/tire contact creates. Check the outer tie rod end also.

The exploded parts diagram shows the suspension wear points:

Upper Ball Joint (item 8)
Lower Wishbone Bushes (5)
Lower Ball Joint (7)
Vertical Link (6)
Hub Bushes (4)
The most expensive and difficult to replace is bearings but still less than the cost of a tyre.
You've only had the vehicle a few months. Any chance you missed the wear on the tyre when you first inspected it and could be chasing something that's already been fixed by the PO?

Thanks Graham,
I have replaced the tyres since I got the car so know it isn't fixed, unfortunately. I'll get the wheel off again this weekend and have a proper go at all the joints to see if I can see any movement when applying force at all the bushes etc. Pretty sure it isn't the bearing, not sure about anything else though!

I haven't had a full alignment check which would have all the angles - I had the tracking checked at a garage who use the traditional optical alignment method, it may be old fashioned but it covers toe-in or toe-out and is carried out by someone who understands and knows how to correct issues!
I had the wheel off again and whilst there is movement in the bushes when levered with a long bar there is no free play indicating that there is specific wear in them - just the movement I would expect from a rubber bush, although they are possibly showing their age and softer than they probably were when new.
Offside/nearside - don't know how it relates to different countries but in the UK nearside is the side near the kerb so it is the left hand side of the car. Those who drive on the wrong side may see it differently
