Scratches on New 108's Wheels

Am I correct to say that light scratches on the edge of the wheel cannot be avoided when tyre is changed? I had all 4 new 108's fitted yesterday. I checked them more carefully this morning, and found very tiny scratches on the edge. I am worried those scratches will again turn into rust eventually. :(

Will tyre fitting machine and tool make scratches?
 
No way. I have had tires put on my 108s with no scratching at all. You are right that scratches will eventually lead to corrosion. Unfortunately, I have picked up a few stone chips in the clear lacquer and am now seeing early signs of corrosion.

My camera is not good enough to show the tiny scratches on the wheel. I'm sure they were caused by the fitting machine. The scratches are parallel and only 0.5-1.0mm wide.
 
Yes it is quite right to assume the damage on that particular wheel will lead to corrosion.

Tyres can be fitted to the 108s without damage but because of the firm nature of the runflat they are difficult to remove and require a skilled tyre fitter. I'd complain but fear you will struggle to prove the damage was not there prior to the having the tyres fitted.

New wheels were supplied/fitted by the dealer yesterday, so I have no problem to prove the scratches were there before. Scratches are not deep at all (0.3mm).
 
Such scratches WILL lead to premature failure of the lacquered rims. they have clearly been fitted by someone who does not know how to work with polished rims and the harder to fit RFT's.

My local guy showed me his machine set up and it runs 2mm above the wheel and as an extra precaution runs a nylon slider on the rim so in effect the tyre is fitted without anythin ever touching the outer edge of the rim.

My new 108's have casting no.8 and the finish of the outer rim is like the old one. The only differnece is the inner rim, the finish is like 135's multi-spoke (shiny not matt). Should those tiny scratches be serious enough to cause corrosion like the one on original 108's? Should I now apply clear lacquer (from touch-up stick) on scratches to protect them against moisture?
 
I would go back to the dealer and complain, mine made sure they didnt bugger them up when they replaced (they know that would only have to change them again).

If they dont want to know then yes apply some lacquer. I did this on my old set where a big chunk of clearcoat had been removed by a stone in the edge of the rim on the insude. It didnt let any moisture in.

So do you prefer the new style or old, I'm glad I got the old as IMO they look better.
 
I like the new ones. They should be easier to clean. I don't think BMW makes 108's with casting no.15 anymore. What type of lacquer should I use? Can I use lacquer for paintwork on alloy wheels?

As you might recall mine are only 4 weeks old and assume they are stamped 15 but cant confirm as delaer has car, so there are still some in the system.
 
I found a more serious problem this morning. I believe the fitter put 8.5J wheels at the front with 225/40 R18 88W tyres and 8J wheels at the rear with 255/35 R18 90W. I measured the widths of the wheels, front pair are 8.0" wide and rear pair are 7.5" wide.

Can anyone confirm that I am right?
 
ksher, something is not right as you say, providing you pictures are in the order you say then it looks a right cock up as both rears look different to each other as do the fronts although it may just be camera angles.

If you have measured the wheels and the fronts are wider then as you say they have cocked up, have you checked the tyres are in the correct place as well?
 
Of course I checked tyres. Front tyres are now on 8.5" wheels at the front, and rear tyres are on 8.0" wheels at the back. :(

Only thing to do is get straight onto delaer and give them hell, and get them to sort the scratches out also.

Bloody Stealers, dont you just hate them :x
 
Will it cause any problem if front tyre is fitted to wider wheel? 225/40 R18 is for 8"-wide wheel. If it is now fitted to 8.5"-wide wheel, is it be over-stretched?
 
Wow - what idiots.

Sounds like you've measured them, but if you want to be doubly sure pull a wheel off and the 8J or 81/2J is stamped at the start of one of the casting numbers on the inside of the stars.

YUou may also find the inner lip of the wheel damaged on the fronts against the struts as they mya be too wide and rub

Not a problem per se as the rims are the same diameter. The only issue will be yet another on and off of a tyre and potential for damage by the fitter, weights to be removed and refitted and as posted above potential of rim damage on the front struts
 
Thanks, CJ. I have no choice but have to get the dealer to fix the mess. I bought a clear lacquer top-up stick from Halfords to paint the scratches. Just hope the fitter will be more careful this time. :(
