Tyres wearing way too fast on Edition 30!

[thomsonpop]

My girlfriend and I both have Edition 30s. I have no problems with my tyres which seem to last about 12 months, but hers need replacing VERY regularly. The current pair of front tyres now need replacing after only 3 months and she only does short trips locally. She usually has Eagle F1s but since someone told her they are a soft tyre, she has fitted a set of Khumos (which are now already on the legal limit!!). Both her usual garage and the tyre fitter can't find anything wrong with the wheel alignment or tracking and have suggested she must be driving too aggressively. Now, granted she is quite a spirited driver, but she's not wheel spinning out of every junction and has deliberately been driving carefully but to no avail.

Any ideas?

Are they wearing evenly across the whole tyre? And is it just the fronts? Print out of the alignment might be handy too.

Appear to be wearing evenly. And just on the front. Going to see if I can get hold of the alignment results. Apparently they just came back to her to say there's nothing wrong with the alignment, but did not produce a printout for her to take away...

This has to be some kind of trolling wind up, or insufficient info has been provided.  No alignment issues and tyres worn down every 3 months, but she doesn't wheel spin it?

I had an Edition 30 for 8 years and my average tyre life was 2.5 years or 30K miles.

I'm smelling manure here.  Tyres that only last 3 months would be scrubbed to f'ck.  If they're completely bald with no feathering, get the missus to stop driving like a chav.

[thomsonpop]

I know! We're both baffled. I know she is not ragging it and yet the tyres last no time at all. Something must be wrong – which is why I am reverting you to guys for possible causes...
Promise it's not a wind-up – I wish it was... it's costing her a fortune...

[pudding]

So there really is no strange steering behaviour, no peculiar wear patterns, no rumbling bearing noises.....nothing?

What the actual in that case!  I think we need to see pictures of said tyres as this is very odd!

[Clarkj93]

Yeah makes no sense... pretty much every scenario that would wear out tyres faster would produce an irregular wear pattern.

Stock power? My F1 Supersports are just about done after nearly 4k but I do drive it fairly hard and ran an APR stage 1 map for a little while which really chewed through tyres due to its awful throttle mapping. The fact that I do literally zero motorway miles also means I'll see higher wear than most.

What mileage is your gf doing

[bobby_fodge]

Swap cars and see what happens to the tyres after 3 months

[thomsonpop]

Going to collate answers to all the questions so you have as full a picture as possible. Thanks for your help guys!!

[thomsonpop]

See here photos of the tyres in question. As you can see the wear is very uneven like there is way too much camber. Could this be a suspension issue? Can't believe the tyre place told her there was nothing wrong with her wheel alignment. Looks like this is the place to start rather than power output, mapping etc?

[Clarkj93]

Yeah there is some positive camber going on there.... it should be about negative .5 to 1 degree. Maybe too much toe in/out too. Either alignment must be out or something suspension related is seriously broken and they should have spotted it! Would try another garage, preferably a highly skilled one over the local High Street garages, if you mention where you are in the world someone may be able to advise of someone local-ish.

[thomsonpop]

Thanks! Yes sounds right to me. My GF is near Shaftesbury, Dorset.

A couple of things...
- Does the car have anything that could have contributed to some positive camber? Adjustable top mounts, wishbone bushes, adjustable ball joints? Perhaps some Powerflex bushes tucked away at the front of the lower arms that you haven't noticed? Is the car on standard suspension? Generally as cars get lower their static camber becomes more negative. If a car was lowered in the past, it could have had positive camber added in order to meet stock specifications. If the car was returned to standard suspension later, it would then be more positive unless that adjustment was taken out.
- You said alignment. Just be aware that some companies will only be checking toe when they say alignment. You really want somewhere with a Hunter or similar setup. Ideally to get camber, caster and toe.

Worn bushes can do funny things, but if your uneven wear is balanced across both fronts, it makes me think that somebody has done something on both sides. Either incorrect part or for the reason above.
