Run flat puncture...

How frustrating......took the gtr out for a run, and just when I was beginning to get into the groove the tyre pressure warning came on.......I watched the pressure in the rear near side tyre go down to zero and trundled the last few miles home....luckily car is on run flats....,,

Am I correct in thinking this means a new tyre as rft tyre can't be replaced and the fact that it has lost pressure means there is a Holbein it?....

Feeling bait pissed off...had loads of bmws with rfts and only ever had this happen once...

Had the gtr less than two weeks and this happens!

|As long as its not a sidewall issue some places will repair RFT tyres. Just need to ask around local garages and see who you might trust to get the tyre off the rim without damaging either the tyre or the rim

Hi


I have just fixed one of the run flats on my 535bmw that had a nail in it because it kept going down. This is fine now, so I would say it can be done on your GTR,The only problem I found was trying to get the tyre off because of the stiff side wall.

Thanks guys......I was starting to feel very depressed at the prospect of having to buy a new tyre....and not having the car on the road for a few days....will try to get it repaired first thing tomorrow......just hope it's not the sidewall!!

Must say, it's timeline this when run flats are very handy....I wouldn't fancy changing a gtr tyre at the roadside!

Sorry to be the bearer of bad news, but if you've driven on a fully deflated tyre, you should really replace it as the sidewalls are likely damaged.
Dynaplug is great, but for when the tyre hasn't fully deflated, or when not driven on.

For Sale section for a tyre that will see you through until the set needs doing?

In General I agree that you should get the tyre replaced if totally flat, however, just think of those poor buggers who have opted to go for non rul flat Michelins or Dunlops :):eek::wavey:

Any way you look at it the tyre retains its inflated shape because when fully deflated it is the sidewall supporting it.
As you drive on the fully deflated tyre the sidewall strength and tyre integrity is further compromised.
Both the Bridgestone and Dunlop run flat tyres are of re-inforced sidewall construction.

Depending on the tread depth you may need to replace both tyres on the same axle.
