Rim Wear!!!

[~Rich~]

Hi guys,
Saw this topic on Disco3.UK and wondered if anyone here has had this rim wear issue?

It is caused by a combination of dirt getting in between the tyre and wheel rim, and the tyre moving On the rim, which wears it away

Seem to happen on the rear wheel mostly, and from what I have seen, with grabber ATs. Whether this is because they tend to be used off road, I can't say...

As per Mikey but from what I have seen on other vehicles it is a combination of the tyre construction and the shape of the original wheel rather than driving off-road per se. The at-risk combinations leave enough of a void for an abrasive paste to form. This appears to do little damage if the alloy surface is intact, but once the lacquer is compromised it seems to eat through the soft alloy at an alarming rate. There have been some blow-outs caused by this.

If Grabber ATs leave this void I would think that the chances of the initial rim damage must be increased by off-road use but beyond this point normal road grime and moisture are enough to produce the abrasive paste. The wheel shape makes this much more likely on the inner rim (I have never seen it on the outer rim yet, others may have) and go unnoticed for longer.

A subtlety different tyre and wheel combination should prevent reoccurrence. Really glad this was caught on a tyre change rather than suffering a surprising accident. Clearly do not use the compromised wheels.

Something to look out for, a bit scary really.

That looks like he's been driving on the rim, no way a tyre could leave marks like that or do that kind of damage.

If that was the case Baz it would be on both edges.

maybe not,, maybe one side demounted

I'd say when he's gotten a puncture, whatever he hit, has push the tyre off that side of the rim, that damage looks like road rash too me, I'd like to see the tyre as well to be convinced otherwise Rich, was there an explanation of how it happened and were there any pics of the tyre that had supposedly did this damage??

No puncture Baz,
Both sides on the rear where affected.

The inner edge of the wheel has been worn away. Both the rears were like this. The chap who did the tyres ( a landy specialist ) said he has seen this quite a few times on models with independent suspension like disco3/4 and rangerover sport.
Tyre wear on the backs was pretty even. No shoulders scrubbed out or anything
Wondering if you guys had seen this before.

I've never heard of this, and I'd imagine you haven't either and given the roads we have here, if it was going to happen, it would more likely happen here, or Sth Africa, even the US.

Interesting...

Perhaps a grinding paste scenario from salt/water/mud and the green laning type driving...

In Oz, perhaps things get a chance to dry, the dirt falls out, no salt and everything is fine...
