so tell me can that be fixed with camber adjustment.or do you have to put some sort of kit in it to fix?cause my old man has a vu ute and some thing is happening,guy told him it has to have some kit put in it costing $600

Part of the problem was that the toe-in bolt was loose. So that rear wheel could independently try to steer a bit. Some wear on the bolt, so am replacing the toe-in and camber bolts when I do the rear bushes hopefully next week.
The other side isn't as bad, but still has some centre wear. I will talk to the wheel alignment people, not sure what the answer is, or if there is one. My previous set of tyres wore the inside of the rears too, yet I get alignments done from time to time.
If I had rotated front/rear more often I would have gotten more mileage from the set, this way I get to play with new tyres.

If like me you ave wider backs than fronts all you can do is swap the fronts from one side to the other and being directional tyres you can't even flip em around.

I recall reading an argument that rotating your tyres costs you money and should not be done unless you want to involve the spare. The proposition was that each wheel has its own little errors in alignment compared with what is supposed to be there, and that the tyre will wear slightly faster to grind off the high points before settling into a stable wear pattern which is related to that wheel's alignment. When you rotate the tyres, all of them are now "wrong" so they wear a little faster until once more there is a pattern across the tyre consistent with the actual alignment errors. Therefore, rotating increases wear, with the only benefit being a visual one that you can not see the unevenness as readily.
I relate the idea, rather than supporting it because I have no good evidence nor additional reports. However, it is true that when my cars had five of the same tyres I would rotate them until the spare was reasonably worn, then not bother any further. Sure, the front tyres in a FWD car would wear quickly but the rears practically died of old age rather than wear. It certainly seemed no worse a strategy.

I think the theory is that one tyre may be wearing on the inside a bit more due to an "error in alignment" or maybe even driving style (ie, feeling more comfortable taking right hand corners harder than left handers or whatever) and then you rotate the tyres and make the wear more even and give the more worn parts a bit of a break. Something like that anyway.

Interesting point Perry.........I've allways felt "Better" about taking LH bends rapidly, but feel "Unsettled" when taking RH bends fast , maybe it's that bias, depending on whether you're right or left handed

Hold a block of wood at a very slight angle and rub it on sandpaper. At first, it will wear quickly, then more wood surface will be exposed to the sandpaper and wear rate will decrease because pressure is reduced. It will look worn, yet wear more slowly than if you repeatedly changed the edge being abraded.
Now, personally I do not drive on wood blocks, tyres are somewhat more flexible and their purposes are different from normal uses for wood but I would still like to have a good idea of what is the gain from rotation other than aesthetics. I can imagine that wholly uneven wear (not using all the rubber depth right across the tyre) would mean shorter total life but would not that represent a significant alignment problem which needs fixing anyway?

David, that theory would work fine if you were prepared to replace one tyre at a time and only when that tyre needed it. Then the next and so on.
Mu rear left was the most worn, followed by the rear right, and the front weren't too bad.
I could have possibly just replaced the rear left, or replaced both rears and do the fronts later, or replaced the set.
As I prefer to do the set all at once, if I had rotated them more I may have gotten another 5k (or whatever) out of them instead of ditching 2 tyres that had maybe 10k individually left on them.
I certainly wouldn't replace 1 tyre at a time.
Yes, it does point to a problem, the toe-in bolt had come loose at one point - or wasn't tightened properly, so the left rear was able to self steer a bit.
Now I have the new tyres fitted, I have a new toe-in and camber bolt on the way and they will be fitted along with all new rear VFT bushes from our friend Mr Vlamos.
Possibly overkill, but the bolt has been shaved a bit by the action of metal moving against it and appears to have come loose again - I can feel the left rear step around a bit on bumps etc.
I don't have a need to replace all the rear bushes either, but this car has been so good to me I am rewarding it by replacing the 15yo bushes and hopefully I will get it just about right back to new car ride smoothness.

Considering the cost of both rear and the front upper bush sets is about what others pay for a single air bag (though the labour will be higher) I think it's pretty good value

My experience over many types of vehicle is that fronts tend to wear on the edges, and rears tend to wear in the centres. The edge wear on the fronts is I suspect because most cars have some degree of understeer designed into them. Rotating them evens out that wear pattern.

I think thats more a mental thing about putting yourself in danger. I think everyone feels better when they have an empty seat beside them as a buffer. If you are about to have a head on, I guess most people would swerve to the right so the passengers side is going to take the impact?
