The A-Class Mercedes was becoming a strong favourite for my new car. I had another drive last Saturday and really liked it. And then I found that, not only did it not have a spare wheel, but it also didn't even have a place where one should go. The MB guy said that it comes with run-flat tyres, so it didn't need one. I wasn't convinced, so the A-Class dropped from pole position to the back of the grid. Everyone else offers a space-saver as an option, except (I think) BMW, but then I was never going to buy a BMW anyway. From what I've read, run-flats are not the most brilliant of ideas, in that, if the car's suspension is set up for their characteristics, you can never use any other type of tyre. Has anyone any experience of them?

The wifes got Bridgestone run flats on her Z4. Eye wateringly expensive and bloody hard. When they needed replacing, I tried to convince her to go with regular tyres but she insisted due to the extra security as she's got a long commute.

I've got run flats on my car. They're very expensive but I got 45,000 miles from a set. The ride quality is very good considering they're 19 inch and the same profile as a rubber band. BMW confirmed that the suspension is tuned for the tyres, so although standard tyres could be fitted it would require suspension adjustments.

I have owned three BMWs, two 5 series, and the last one a 1 series with run flats. The drive was hard to say the least. I got a puncture in the Scottish Borders, miles from anywhere. I had to crawl home, about 40/50 miles at slow speed till I was in a position to replace it. I vowed never to have another car if they were fitted. So far I've stuck by my word.

They offer a firm ride and are expensive to replace. Plus, it must be said, the experience when 'running them flat' leaves a lot to be desired. I used to think spacesavers were the devil's spawn but runflats now take that accolade. It's a cheap way for the manufacturer to save money and it stinks. Their excuse is that we get more boot space and that our cars perform better due to the shaved weight. Utter crap. Give me a proper spare! :grrr:

I can (just about) remember when you bought a car with alloys and even the spare was an alloy. That's how it should be IMO. Far more user-friendly and cost effective. Get a flat, bung the spare on, get the flat fixed (with a tyre of your choice) at your leisure and then throw that back in the boot. :^

Of course you can run normal tyres instead of run flats, after all there's no problem in putting winter tyres on a car, and they're not run flats....

I used to run run-flat Bridgestones on my 3-series. Hard, noisy, reduced handling. Bloody expensive. I have since replaced them with Goodyear F1. Way better and cheaper. Plus, one of my run-flats blew up in the Moracha river canyon in Montenegro. It not just got punctured - it practically melted after 200 yards!!! In the middle of fucking nowhere. Avoid!

Tbh, there's not actually that much difference in ride quality between my run flats, and winter tyres on my 5 series...

And the run flats are on 19" wheels, the winters on 18" wheels... So go figure??

Oh and the winters come with a can of tyre weld..

I don't have run flats on my Honda but mates who have bm's with them get shot asap, my S2 is at 15k miles and soon needing second set of rears and a set of fronts, don't you have corners where you are.? Then again my car is often driven like I stole it.

But are the winter tyres not also run-flat types?

I have a BMW which comes as standard with non run-flat tyres (and a can of tyre weld).

A buyer can specify the same car with run-flat tyres. I wonder if BMW modifies the car's suspension for this different configuration? :?

Bugga! I'm sitting in the local dealer, about to have a flat tyre replaced :doh: .

Hi, my folks have a B class 180CDI Sport, they got it in October and it has run flats too, I have driven it a number of times and the ride is surprisingly compliant, I was a bit worried that the ride might be too hard with them on, but its ok, my folks have got about 1500 miles on it now, and they love the car......and they're getting 60+mpg too, must admit it's a nice machine, very well screwed together as well.

I have, and they are not worth the hassle, you can only do a max of 50 miles on one that has a puncture....and a max of 50 mph, so basically as soon as you get a puncture you need to replace it anyway, any other tyre you can usually get it repaired for a tenner.

I sold 4 brand new run flat tyres 3 years ago for 100 quid, yet they cost me a shit load more than that.

bottom line, dont bother.
