Tyre feathering 10k miles + SSTT fitted :)

dazzapb · 08-30-2008, 07:59 AM

Guys,

Sorry for posting a new thread re: tyres again!

Anyway, I noticed that the inside edges of my tyres have been feathered, there is almost no thread there! they are bridgestone re050a run flats. (19")

Take a look at the picture! is this illegal? I believe the law states 1.6mm across 75% of tyre

my car has only done 10K miles!

Why would this happen? I keep the pressures pretty much at recommended levels. I do tend to power out of corners, but rarley break traction, and I like to put my foot down

At £300 a pop am I faced with a big bill? Perhaps I should change to non rft's now.

On another note I fitted the SSTT this morning. Oh my god!!!! it makes a massive difference. what a car! its scary fast now, stupid fast!

The traction control light comes on in the dry! through all gears. Its almost like a fairy light!

Looks legal enough to me but when you do change tyres it will need re-alignment - that, I think is what's causing the uneven wear. My tyres were a lot worse but wearing in a similar way at the inside edge and I had to get the whole KDS thing done.

Yup, the SSTT is good isn't it? I found the same, the traction control light was on much more frequently.

Sorry to correct you a little bit, but when you change tyres, there is absolutely no need to have a re-alignment done, just because of the tyres. A change of tyres to the same dimensions has no bearing on alignment issues.

However, the alignment may need to be done as a seperate issue if you are experiencing poor tracking, uneven tyre wear etc etc... That is independent of the tyre choice or change. Looking at the picture of your tyre, I would suggest two things - firstly perhaps it is a tiny bit over-inflated for the load of the car, or the camber needs adjusting to give more negative camber in line with BMW specs. The only way to tell is to get a KDS alignment check as an initial step.

thanks guys. Tony, re: KDS, can this be done under warranty? the car is only over a year old

Also how much would it be? Any recommendations on places to go if I have to pay with my own dinero? I am in the Richmond area

Thanks!

DaveC · 08-30-2008, 11:01 AM

Looks like its out of alignment AND been over-inflated to me. Its not legal due to the wear in the central section (1.6mm over the central three quarters).

Answers in order - no it can't be done under warranty. BMW UK only give an arbitrary goodwill for the first 3000 odd miles, or 3 months of ownership, in terms of an alignment check.

A proper KDS needs to be done, and truly the best place is BMW Battersea (which is where my car goes now). Cost for the KDS is £298 inc VAT, fixed cost. They budget for two hours of labour, but in real terms it will take longer than that. If you want me to help you book it in, let me know - will jump the queue for you!

AlanQS · 08-30-2008, 11:04 AM

I've googled without success. What does KDS stand for?

Agree... should have lasted more than 10k miles.. should get it checked before installing new tyres

9.5k miles and I have to get a new set of tyres! kiss goodbye to 600 notes

Oh well - maybe I should get non run flats all round!

Thanks Tony, will PM you if I decide to go with them, after checking finances

Might go with feltham tyre centre - looks like they have the hunter equipment

cheap at £80 but maybe not the real deal?

Pressures in the rears has always been 2.6 bar,

0.1 bar less than BMW recommend on the sticker for 2 people

You're right though it does look like over inflated wear

If the tyres are showing uneven wear like the one in the picture then it is very advisable to have a full KDS wheel alignment done - ideally before the new tyres are fitted. I do think you will find that wear on the inside like that is very likely to be a wheel alignment issue - I know, because I have experienced this a couple of times now and in each case the tracking was, indeed, slightly out.

I didn't say you needed to have wheel alignment done just because you are changing tyres -this is something you have taken from my post without it being spelt out as such - as I was referring specifically to the picture presented, which, does look like there is a tracking issue. I reckon if the OP takes his car to BMW they will recommend KDS before the tyres are changed otherwise they are likely to wear the same way.

Scotthall in Watford were doing full KDS for £190 recently as I had my 335i done there.

How are your front tyres wearing? My rears were exactly like yours and had never been over-inflated. The fronts were wearing unevenly too but the outside edges were most affected.

fronts look perfect really. Even wear (almost nout to be honest), infact the front left was replaced about 1,000 miles ago due to screw in tyre - at least I made one claim on tyre insurance.

Seriosly thinking about changing to non RFT's now! after KDS

might be able to sell fronts on fleebay!

dazzapb · 08-30-2008, 01:37 PM

ok going to get non RFT's and rape my credit card!

So guys, as I have the 225m's what tyres do I go for and from whom?

I can entertain the "cheaper" brands, such as vredistein, falkens etc, think PS2's are out of my price range, unless anyone can suggest a good broker? even the ZP tyres sound great, but I cannot find any on the interweb

Are they 19"s ?? Then PS2s will be roughly £950 all in, balanced and fitted (from Elite in Romford).

Continental's are less, at about £800 - £850. Pirelli PZero Neros likewise.

Falkens I believe are around the £600 mark...

big pimp · 08-30-2008, 01:45 PM

dazzapb - i recommend you get round to your local BMW dealer ASAP and get your car KDS'd and get this problem sorted pronto.

i have experienced the exact same problems as you, and my car is now in a sorry state where i have to replace all 4 tyres, and also 2 rear alloy wheels due to there being 6 hairline cracks on OSR alloy and 4 hairline cracks NSR alloy which i have attributed to my car being out of alignment since day one.

some pics of my wheels (rears with approx 5 k, fronts with 20k!):

front:

get it sorted as quickly as you can mate, or you could be in the same unenviable position as me trying to argue with your stealer over who is going to pay to get my car sorted.

dazzapb · 08-30-2008, 01:46 PM

indeed they are 19" Tony, tyres are 225/35 at front and 255/30 at rear. Thanks for the tip!

You might also want to check out this previous thread, in which I explained a little about how a KDS works...

Wow big pimp - thats pretty much identical wear to mine!

Thanks for the advice mate, will call the dealer pronto. Question - did you have to pay for KDS, replacement tyres and alloys.

What pisses my off is that the car was in the stealers recently to have the drive shaft replaced, and wheel bearings etc and no one flipping mentiond anything!!!!! they must have seen this up on the ramp!!!!!

Cheers mate!
