I am on 2nd set of bridgestones, 34k now
1st set lasted for around 2 years, +/-22k but outer edges of the front ones had been worn badly.
The reason being - not doing alignment at all in two years.

Don't want to start this but for me RFT's are a more convenient as you can easily drive to the garage in case puncture. This happened to me 3 times and got it repaired for a tenner each time.

What are the correct pressures for 20 inchers? I just got an E70 35D M sport last week so still getting used to it.
[/quote]If its not fully loaded its 2bar front and rear.

All tyre pressures should be labelled inside the drivers door shut. 

Switched our X40D from the Bridgestone run-flats to the Yokohama Advan V802 non run flats and WOW what an improvement.

Only drove the car briefly (before returning for another extended stay at the dealer...) but straight away noticed they were quieter, smoother, more comfortable and the ride quality at speed now feels a lot more controlable with less time required for the chassis to react to bumps and undulations at speed.

We just have an inflation kit in the boot in case of emergency.

Will be posting the Run-flats up for sale in the next day or two if anyone wants a set of four

Interesting... What's the approximate cost of a set of non-RFTs?  My experience of Yoko's in the past have been fantastic grip with the obvious trade off on wear and tear.  How many miles have your RFT's done?

Nice to see you were able to have run flats repaired, a few weeks ago we picked up a screw in one of the rears, no one would touch it as they said run flats could not be repaired under any circumstances, got into a bit of an argument with a large Bridgstone tyre dealer about it, even made him look at Bridgestone's web site in which they say you can repair a run flat like any other tyre.  In the end I found a local garage who would repair it, but then changed there mind when it was on the ramp as they said run flats could not be repaired, again went through the look at Bridgestone's web site talk.  In the end the screw had not gone right through so no drama.  But how can people who sell Bridgestone tyre's argue with the manufacturers own information??????????????????????

Technically RFTs are not supposed to be repaired, so those who only go by the book won't touch.  I'm lucky in that my local supplier just verbally tells me that, and then fixes them....

This is true up to a point

As long as they have not been run 'flat' for too long then this is ok

If this is not the case then the heat build up on the squashed side wall will weaken the side wall and you could be prone to a blow out.

I can only go on the documentation I have seen.  My local repairer showed me his file.

It is the manufacturers who state they must not be repaired, not me.  Only one manufacturer has published a document telling tyre suppliers that their tyres may be repaired - I think it was Brigestone but can't be certain as it was a couple of years ago.

Mine are both Dunlop & Pirelli and both manufacturers state 'do not repair' and there is no qualification about how long they have run on flat.

I've heard of people repairing RFT tyres, but like some of the experiences shared today I've always been told this isn't possible by more reputable and trust worthy sources.  If it's not recommended by the manufacturer, is it worth the risk?  Perhaps I would feel differently if the tyre was a month old.
