Run Flats - Advice

[Matt35]

Evening all,

I have a 1 series with these on. In may had a rather large stone go through the tyre, took it a tyre place - repaired drove off - No issues since. Rear of Drivers side.

Yesterday - noticed a screw embedded in the rear passenger one - so took it to a certain K fit place, said they couldn't repair it would need replacement, then said I may as well change both rear tyres as the other shouldn't have been repaired, this them moved onto changing the set. On my 10 plate car with 5500 miles on it!?!?

So went to a local tyre guy, he confirmed couldn't be repaired so ended up changing the tyre to some rubbish budget make, Nokia or something, have goodyears all round otherwise. (mrs in hospital, rushing about, just wanted it done)

So question.....

1 - Can run flats really not be repaired? (initial research suggests this actually the case)
2 - If above is true should i change the one that has been repaired already?
3 - I have now have two different tread types on the rear, should I swap them to the front or leave as is? Suggetions??

Thanks in advance

Matt

Run-flats can be repaired (within reason) - provided that they have not been used while deflated. The theory is that in run-flat mode (little or no air) the side-walls take such a pounding that they will get you home, but are structurally damaged and should be replaced.

When I punctured my 1er's run flats nobody would even have a go at repairing; it was straight into a new one.

I would want the same tyres all round or at least the same tyres on an axle.

Ok - The one that was repaired was flat by the time I get to the garage, should I replace then - since they repaired it, its been fine (pressure as well)

thanks for the reply

Thats what i thought, in that case should i swap the two on the front to the rear and vice versa?? or just swap the "budget" over - Only went for this as its the one they had in stock and just wanted it done whilst I was there.

I had a 1 series. I was advised by several garage that they're particularly sensitive to tyres when it comes to handling, and told that at the very least the tyres on each axle must be a match.

I was also told they shouldn't be repaired. HTH.

Was the replacement a budget? otherwise your stuffed if you get another puncture as no spare. you can carry a can of tyre inflator though.

Well they would tell you that ... Run-flats are expensive (profitable)!

The new one did not come from the Kwik-Fit or the other garage who both wouldn't repair it. They both new that I would buy a new one from BMW.

If it's a Nokian, it's not really a "rubbish budget make".

Twice in 10 minutes? Wow, you did have lots of punctures.

It depends. Not being reparable is complete bks. I have an article somewhere in an IAM magazine written by Dunlop which states 100% clearly that they can be repaired.

If they have been run flat for any great distance then no, they should be replaced. The line that the tyre places give is that they cannot tell if it has been run flat. Again, not true. When the tyre is run flat, for a some distance we're talking 70-100 miles it begins to break up, and you get little balls or rubber in the tyre, if they're not there, it's fine to repair.

So limping 5-10 miles gently to a tyre place is no big deal, as the tyres are usually fine for around 150 miles flat.

Thanks for all the reposnses!!

it is a Nokian that was fitted, should i have the same tyres on the rear and put the nokian up front or leave as is?

Back home now so can have a fiddle around (mrs out of hospital with my baby boy)

Get rid, run flats are sooo expensive. My 2004 Cooper S had them and they cost a fortune if they had a puncture, and if they did I believe they can only be repaired once. I never use kwik st due to they're prices, IMO ATS are far better and don't give out the bull st kwik st do.

My new Cooper S has split rims and no run flats. When I got a puncture within the first week of ownership, it cost a couple of quid to fix. Luckily I have a tyre inflator and have bought a tin of tyre weld just in case I can't make it the few miles to my local garage!

I agree with the above, I've got a 1-series on run flats and had a puncture a while back. I would have probably got it repaired if I could have stopped quickly, but unfortunately I had to drive another 50 or 60 miles on it. I started off by topping it up, but the further I went, the faster it deflated.

It was quite obviously fecked by the time I got to the tyre place with very uneven wear on the shoulders, presumably where the sidewalls had supported the tyre.

Painful at 185 quid for a front tyre (BMW dealer quoted 240!!), and when they're worn I'm swapping to normal tyres and a can of spray.

I've been told by BMW they will not repair RFT's (on the 3 occasions I've had punctures!)

I've now got a new set of RFT's on the rear as I was told that the warranty would be voided (suspension parts) if I did not use thet're recommended tyres.

I now need to change the fronts but I'm now at the end of my warranty. Can I go for non RFT's on the front and still run RFT's on the rear untill they need changing? Is this going to make the handling feel too odd?
