E39 rear tyre rub help needed.

[Haz77 0]

Hi,

Noticed the inner edges of my rear tyres have rubbed out to canvas right on the edges, not like you get when the camber or the trackings out but like they have been touching something, the wear is about the size & shape of youe thumb nail at 45' to the edge / corner.

Car is a 2000 530 motorsport, all stock, 17" 255/35/17 not lowered etc.

Only thing I can see that might be in the right place to cause it is the bottom of the shock spring coil assembly but I thought the shock moved up with the wheel and its miles away when parked up.

its the same on both tyres, I have heard a scuffing when I drive at speed through a dip in the road but thought this was the outside on the arch as they are quite close.

Any ideas before I replace the tyres & bugger the new ones?

Cheers.

If it is a stock original car, firstly get the rear wheel alignment checked.

I would say though it will be the tyres you have fitted - with too soft sidewall construction. I had exactly the same with ours, albeit on 18's when shod with Toyo Proxi's. They were fine on the front but terrible for cutting out on the rears on inside shoulder - as you describe. Slow learner as I wore two pair on the rear the same way.

Changed tyre brand & no further issues.

Running Dunlop Alzzeras (?) front & rear so would have thought they are not the issue but they are almost finished so maybe theyve just had enough, very strange to look at though just like they have rubbed on something.

Will see if I can get the alighnment & camber checked when I get the tyres done this week.

Cheers.

Ideally you want a load rating of 97 or higher to help prevent it, but I hear that a small amount of rear suspension wear can accelerate the inner wear on the rear. E39's tend to wear rear inners anyway.

Wierdly, we have inner wear on the rear of ours (I very recently rebuilt the rear end) but it's showing a tiny amount of canvas BETWEEN the tread chunks! There is still plenty of tread, so I'm not sure how it's done it. They are cheap crap tyres though - I can't even remember the brand - I can't wait to get rid of them though!

Sorry 255/40 fitted not 35s

Thanks for the replys, dont think many people would consider Dunlop dezzeras "rubbish tyres" but I have no idea how old they are & they where pretty much bald so wouldnt rule out tyre failure.

The cars in for a service today so asked them to check the rear set up & if it all looks ok Ill get an alignment check done.

Got the new tyres yest, went for Achilles ATR sports, not a big/known/mainstream brand but at $180 fitted they sure are good value, closest other quote I could get was $260 for Dunlop sport max. the Achilles are 99r rated so that should rule out under rated tyres also.

Did a google first an lots of good comments on achilles, this one sold me from a Oz bmw e90 forum;

oK, well thanks for that, opinions & info are why im on here, tyres are on now & I obv cant take them back based on forum posts, that said I wont be throwing the invoice out & im no stranger to the small claims court & consumer rights when it come to "fit for purpose & use" so will see how we go.

I do believe that something as serious as side wall failure occurring even to one guy is one to many and if the ratings are not reliable or true I find it worrying that the industry is not regulated to prevent this.

They came from a goodyear tyre centre & I didnt ask for the cheapest just told them the size, the guy assured me hes sold heaps & had no complaints or bring backs, maybe Ill be the first!!

I dont drive hard often, 85% of my use it to & from work just cruising along, the few times ive turned the DTC off to get a feel for the car the wheels have just let go without any hesitation, when on very rarely does it cut in even when Im pushing it & I would never dream of driving in the wet with it off as the wheels will clearly just spin with the power of the car regardless of the tyre.

Im not 18 or stupid so not looking to "race" or drift the back roads, I dont track race or Autox (whatever that is) so I dont see the value in me fitting top spec tyres just because I have a motorsport badge on my car.

I am disappointed to hear the bad reviews & I will be looking at the wear & checking the side walls regularly but I brought them in good faith from a reputable tyre suppler and if they are not suitable I will have no problem with going back to them for a refund or exchange.

finally, garage found play in both lower rear bushes so will be getting them replaced asap, out of interest they said about $500 for both is that about right / could I do the job myself without a bucket full of special tools & knowledge?

Thanks for the heads up & warning.

They may be referring to the rear lower balljoints - the have a bolt right through them.

You need a special tool to change the rear balljoints easily without removing the lower arm, but everything else is press in, press out (although a proper balljoint splitter of the correct dimensions is required to not damage the balljoints on the arms and aluminium carrier). If you fit new arms, the bushes are generally already pressed in anyway.

If you're doing that kind of work, replace the bushes/arms and balljoints - why to the work twice, and if one part is rooted, how far behind are the others??? I got all my stuff from paul at Milland, including genuine rear balljoints.
