How far have you driven on a flat run-flat tyre

[Anonymous]

Yesterday, driving a Mini Countryman on Goodyear run-flat tyres from Haslemere in Surrey to Corby in Northamptonshire the TPMS warning for the the front offside wheel lit up on the M25. At that point I still had 84 miles to go. I reduced speed to 50mph and pulled into the first services available to investigate. Taking a quick look around the tyre I couldn’t find anything obvious that had punctured it (was wearing smart clothes so wasn’t about to get down on hands a knees and get messy!) but putting an airline on the wheel, I could hear air hissing out almost as fast as it was going in. Being under time pressure I decided to see if I could complete my journey. So, keeping speed to a max of 50mph and taking bends and corners gently (and stopping once to check the condition of the tyre) I got to Corby without any drama. The tyre was slightly warmer than the others but had done the job it was designed for. Impressive! However, I’m still glad I’ve no longer got them on my Zed

100 mile you need to go steady and stop around 25/30 miles to let it cool it was raining when I drove on a flat on my 1 series so drove through the puddle's to keep temp down the next day when I put a new tyre on it was starting to delaminate

These have a similar ride quality

I had similar experience on my mini ironically, my tyre pressure warning light came on as I was overtaking a car with caravan at 75 mph in a tight spot on a B road. I carried on overtaking then turned off to find my tyre was hissing air out. I drove for about another 30 miles at up to 50mph initially cornering carefully but then decided when roads were clear to corner as I normally would. very little difference from when inflated! So they do what they are designed to do very well. But the lack of comfort on poor roads is horrendous so I replaced them with non runflats. I have just replaced the runflats on my Z4 with non runflats and it is like a different car, it used to tramline chronically and I got pitched all over the place on bumpy B class roads, so much so there were roads I avoided. It's great now.

Having said all that my wife's e91 3 series estate executive is also on runflats, the ride is no problem and it doesn't tramline at all. But the springs are very compliant the rear spring coil diameters are tiny (look like about 10mm! but i hope a bit thicker). I will probably keep it on runflats on this as the car already rolls way too much for my liking and I don't want that to get any worse.

According to the handbook for my E90 330i it can go up to 150 miles flat if the car is lightly loaded (i.e. 1 or 2 occupants and no luggage) but I'm not sure I'd want to go that far at 50 mph. :roll:

The first time I got a puncture in my 1 Series it was snowing, and I was on my way to work suited and booted (back when I had a proper job)! I just carried on to work a few miles away. Went out at lunch-time and drove it 20 miles or so to my usual tyre supplier and had all 4 replaced as they were nearly finished anyway!

The second time it happened I was leaving work in the snow again - which is one of the reasons I quite like them! I was only 5 miles from home and I checked it when I got there. It hadn't lost much pressure, so next morning I inflated it slightly above pressure and drove to my tyre place about 10 miles away. They repaired it for £10 - result! I got another 11,000 miles out of it!

Both times it drove fine - you wouldn't have known without the warning system!

So they'll be staying on the 330i - still undecided on my Z4. I'd like to try it on non-RFTs, or at least have a ride in one that doesn't have them.

They might look ok on the outside but its the inside that wears and breaks up.
From what I have read even driving a few miles is enough to wreck the tyre.

Mine went on my 4 series over the last xmas period.

I was trying to wait it out for 4 days to get back it back to work and get it changed (company car)

Unfortunately it got worse and worse and I had to bite the bullet as it was in danger of coming off the rim. Kwik Fit were the only ones with the correct tyre in stock at £190.

I drove about 150 miles on it but I'm sure the handbook said no more than 50.
