Another Reason to Ditch the Run Flats?

Took my car in to have the OEM Bridgstone Run Flats changed today, a job I hate having done as it usually results in wheel damage, but I spoke the owner last week, and I think he knew I look after my car. It's a local company I use and they used to do the BMW dealers tyres until they got their own facilities.

Anyway been there for an hour and a half, he was taking his time, which I didnt mind as this would hopefully mean less damage, when he popped his head round to let me know both front wheels were buckled. A colleague showed my the worst one on the balancing machine and as clear as day you could see this flat spot on the inside.

Runflats must cause this more than normal tyres with Pot holes etc, so another good reason for them to go.

Anyway long and short of it, Falken 452's now installed, I cant see a single mark on my Rims, and there is no problem with wheel wobble or Vibration up to shall we say a significant speed.

He also gave me the following valve as the valve stems are very short, but the longs one are to long. Anybody any experience with them?

Screw onto valve stem and attach airline to use.

Doesn't that mean you need new wheels though?

I need new wheels but not for that reason, you can guess the other.

I wonder how many other owners with 18" Rims and RFT have buckled wheels I know it will affect all wheels even with NON RFT's but the increase in sidewall strength must play a part.

Car going back to BMW on Friday and I have asked them to remove all wheels to view the corrosion which they cannot find (because they dont takes the wheels off)
 
When I had my inspection 2 done the service manager said that the wheels on the left hand side were slightly buckled and that the car must have been in a big pothole with the previous owner or somthing. Mine had 19" twin 10 spokes (think they're called Mtech 2's or something?) on it with non RFT's when I bought it.

I noticed afterwards that at about 80mph the car vibrates quite a lot from the front left wheel and that this is more noticable when there is a passanger in the car. The dealer did a repair on the front left tyre and I had put it down to the wheel not being reballanced properly as I had not really noticed the vibration before the insp 2, but then I had only had it just over a week before the service so was very much still in the honeymood period.

Can anything be done to straighten out a buckled wheel, as I do quite like mine. Interestingly the serice manager tried to sell me the reconditioning they offer but if the wheels are shot anyway i may aswell start again with some new ones right?

think you will find they were 18" MV2's, yes they can be crudely repaired, but wont be trying it with mine as there is no problem caused.
 
I've always been under the impression that anything 18" and up is susceptible to damage thanks to the lower profile tires, runflat or not. I'd love to put some 18's on my car, but the roads I take to work frighten me with my 17's. Some sections of road shouldn't even be called road. :x

As far as those valve caps go...I used to use something very similar on my RV. They seemed to work just fine. Obviously that little button in the middle contacts the valve stem, so when you insert a gauge or air line, it presses down the valve and acts just like you were connected to the stem. Should be fine with them, I'd just check your pressures a few times over the next week to make sure it's not causing any slow leaks.

They only gave me one valve, I still use the standard metal caps, only this when checking and inflating.

When I had my FK452 fitted yesterday the front nearside was flat spotted on the inside... a nice dink. It'll repair of course, it looked fairly long (3"), but not a huge deflection, and it wasn't losing pressure etc, but I'm not sure if an MOT tester in a bad mood would like it lets put it that way.

It balanced up really well though, with a 5g weight.

The fitters said that they dink on the insides alot with RFT''s as they have alot less sidewall give.

So, another job to get sorted.

Tempted to sack off these 108's too. Nothing but a liability, and common all said and done (seen tons on eBay/sales sites, but not one set of 107's)



Good luck with it anyway :)
