Annoyed

[mj2k]

Feel for you, had that 3 times in 4 weeks before, luckily on a company car. Remain convinced someone thought they owned that piece of public highway (not infront of their house, or anything uber petty), and did it over night.

Currently the M has a really really slow flat, need to get it sorted, can't see any damage so no idea if anything can actually be done.

Same for one rear on mine, tyre shop cleaned up the rim and checked for cracks before redoing the bead and putting the tyre back on. Trouble is, now it's losing air faster than it was before...

Arse, was hoping to read it fixed it! It's so slow I can live with it based on infrequent use of the car, but annoying.

Was tempted to change all the rubber as bought the car on 7k and it's now 24k, but convinced its the original rubber. Need to find the right tyre though given the Michelin changes, but guessing I'd rather lose the last couple mm of tread vs a blow out due to age of tyre.

Runflats don't just blow up after 50 miles. I have no doubt you could travel 100 miles on it or more with care. Think cold wet night, female, alone, etc. Or dangerous motorway hard shoulder. It'll get you to safety and out of danger.
Second big factor is packaging - there just isn't the need or space to carry a big tyre around in a modern car
I dont like runflats but understand the need

I'll second that - About 6 years ago, when I used to hire cars out tas taxis, I had a pair of part worns fitted to the front of one of my Mondeos. Gave it back to the driver that night, the following morning, her rang to say he had a screw in a tyre, but had pulled it out and the tyre had not gone down (although I later found out that the muppet hadn't actually checked the pressure) anyway, two weeks later, I got a phonecall to say he'd had the same tyre "fall to pieces" at low speed - Turns out the garage had fitted a runflat, he'd then driven on it for two weeks, or at least 1500 miles with NO air in it before it fell apart...

Oh happy days - NOT..

Mostly convenience - I only had 2 punctures in my 123d quite near home, but both times it was snowing so I was rather glad to have RFTs!

Also useful if the OH uses the car as most wouldn't want to be changing a wheel!

Or they let you can get off a motorway - I wouldn't want to change an offside wheel on the hard shoulder! :thumbsdown:

Anyway my Z4 owner's handbook says 150 miles with a light load (1 occupant and no luggage), 90 miles with medium load (1 occupant and a full boot or 2 occupants and no luggage), dropping to 30 miles with 2 occupants and a full boot.

Interesting point Nictrix makes - OP, did the tyre pressure warning light come on? If not, you may still have an air-tight tyre. And even if not I'd be happy with a repair on that - I did 11K miles on a repaired Pirelli RFT on my 123d with no problems.

But having said all that I'm planning on going non-RFT on my Z4 next time I buy tyres (just bought a 17 inch space-saver). 8)

If you're not sure how old the tyres are they should have a date code

No idea that existed at all, and petrified!

Away on business, so will look at the weekend & update. :!:

Would replace as you said a blow out made a real mess of a mate and his TVR

Here's a source of useful information on runflats and repair advice regarding the different makes http://www.etyres.co.uk/run-flat-tyres/repairing-run-flat-tyres/

Only a few weeks ago I found a nail in a rear tyre on my ZED - it was just off the centre line of the tyre. Wasn't losing any air and could have been there a while. It was a Bridgestone with less than 5000 miles of use :-x Anyhow, I was pleased to find a local tyre service that could repair it - obviously a massive saving on cost of replacing the tyre - phew!

I had a similar puncture with a screw and a washer. I could feel it before the flat tyre gauge lit up. New tyre. There's load more crap on the roads nowadays. skip lorries and builders vans probably increase this kind of stuff.
