I switched on to non run flats on my E85 roadster, and it made a big difference to the ride. That was on 18's, so not sure how much difference it would make on 19's.

I've personally never heard of anyone going back to run flats after changing. As long as you let your insurance company know you should be good.

Oh, and get yourself some decent tyre gunk just in case.

Why would you need to do this? They are only tyres.
All the research I did before switching suggested it was something that should be declared. There were varying responses from insurance companies as to whether they were bothered or not. It's just one less excuse they can use to invalidate the policy I guess.

Ride quality is better and non-RFT are a lot cheaper. Its a no-brainer. However my tale should be considered. Three weeks after doing this very change I had a puncture. Evening time 200 miles from home. Foam didnt seal it so nightmare journey involving hotel and local tyre dealer ripping me off. Get youself a space saver to save the risk.

Joined the RAC if they can't fix back of a lorry, covers all posabilities and not that expensive. Paid dividends when the M3 dropped a anti roll bar tie rod on the M25, it was very helpfull and waited until I pulled into Clackets Services, plus when the roof is down and folded up in the boot there is no boot LOL still the way to go though

I had a similar scenario with my everyday car, but it was fitted with runflats. I was on a motorway and by the time I pulled over the tyre was complete junk. It looked ok from the side but was starting to break up in the centre. I just dare not risk it.

So I suspect that it's just one of those things.

Anyone who owns a car that's out of manufacturers warranty would be best advised to get some kind of Relay insurance, either AA, Green Flag or RAC. It's not ideal to be broken down, but at least you know someones there to help. They got me out of deep dung on that occasion. It makes the journey far more relaxed with the peace of mind.

Another top tip is that when it comes to the AA's renewal they try and charge you more. I rang up to cancel and was going to rejoin as a new customer, but they soon dropped the price. A strange world when they try and scam they're existing customers isn't it.

Just bought a set of Michelin Pilot Super Sports before all my fillings come out, so if anyone wants the old runflats two x front done 20k 50% worn and 1 x rear done about 3k mint they are 19" x 255 x 35 front and 255 x 30 the rear £50.00 the lot.

From Wikipedia "Run Flats typically provide for the vehicle to drive for 50 miles (80 km) at around 50 miles per hour (80 km/h). However, if the tires are subject to this kind of misuse, they may become irreparably damaged in the process"

So inevitably they have to be changed for new if they are driven on flat, and so do ordinary tyres, so i suppose the only advantage other than cost is the run flat will not disintegrate and fly off the rim, and most people i know who have had a flat on theses have had to have a new tyre and not a repair, seems an environmental nightmare to me.................sorry rambling...........

Had my first experience with run flats today, £203 worth of experience...I had hoped to get the wear out of the tyres before swapping over to non-run flats but found myself with a puncture, normally repairable with a standard tyre, screw nail through the centre of the tread, the garage said they can't repair any puncture on run flats (true, I don't know?) but being Sunday I was only to glad they had an exact spare on the shelf and I could get going again within the hour...

Really do hate these things, had issues with a slow puncture on my Cooper S before it was traded...I just feel the tyre manufacturers are taking the Pee with these tyres and would never opt to have them other that them being standard fit to BMW these days...so much more expensive, not as good a ride, that said the only saving grace is you can get home I guess but how far you can travel has got to be debatable, my punctured tyre was on the hot side after only 10 miles from the warning light coming on.
