On the A250 Engineered by AMG:


1. Does it come with Run Flat Tyres?



2. Whats the situation with the Spare? Does it have one?



Reason I am asking is I currently own a BMW 5 Series and that has RFT, which I dont really like. It also does not have a spare or a Jack. RFT's are annoying when punctures happen as you are not supposed to get them repaire (I have done in the past though).



Thanks in Advance

Hi it doesn't have run flats or a spare. There is a 'tirefit' kit in the boot which is tyre sealant and a compressor. I wasn't terribly happy about that but then I can't stand run flats

Thanks Mbznut.


Im glad it hasn't got run flats! A wee compressor will come in quit handy for checking your tyre pressures now and again. I usually do this once a month.



I assume the tyre sealant rights the tyre off if/When you use it?

Oh well, still better than RFT's though!


Wonder how much a new tyre is? A few hundred quid anyway!

My A220 has run flats as part of the AMG pack. I was dreading them as they are so harsh on BMWs but the MB dealer assured me the MB version is much more of a hybrid and has a far superior ride to the tyres BMW use. I have to say I have been very pleased with them so far - excellent handling and ride. Replacement cost looks good - about £150 a corner for mine.

Having said that, I long for the old days with a proper spare in the boot!

I like a spare, there is something reassuring about a spare. Good to hear your run flats are good mon2s. Merc told me it was a weight saving venture to do away with spares. Some models have them though.

Its strange in these days of obsessive recycling that we have become the opposite with tyres - one puncture on a run-flat or a tyre-weld use and you have to replace the tyre. Madness!

Its all about money I think. MB must save a fortune not putting a spare in their cars. I mean a steel wheel with tyre must be about 100 quid as opposed to 20 quid for a can of tyre weld and a wee compressor.

My a250 has RFTs, there not too bad. I'm still going to ditch them as soon as I can and go back to normal sport tyres, made the same change on my bimmer and the difference was like night & day.

If your alloys are fitted with run-flats, can you fit standard tyres when the time comes or do you have to fit different wheels?

You can fit normal tyres to RFT wheels but not the other way round, the wheels have a small rim to stop the tyre coming off once it deflates. Edited by: aguycalleddb

I too was dreading the run-flats but I pleasantly surprised and the ride seems just fine to me!

The reason manufacturers are putting in in inflation kits or RFT's is down to the emissions that they can publish, the weight of a spare bumps up the emissions and therefore road tax and company car tax etc.
