Are my tyres run flat or not?

Found 29th Mar 2016
I've just purchased a second hand bmw x3 from a garage, which doesn't come with a spare tyre, instead it's fitted with run flat tyres. The tyres are pirelli cinturato p7 225/60 r17. I've never had run flats before and the garage assured me that the tyres were run flat. Two people since then have commented that the tyres don't look like run flats, while getting a new tyre for another car today I enquired about the tyres and the guy said that they don't look like run flat. Is there a distinguishing mark on run flats that will tell me. And if they are not what can I do about it?

They should have RSC on the tyre

Run over a nail. If they stay inflated they are run flats.

Seriously does it say on the tyre wall? Google the make and see what that throws up

I had a similar problem when the garage sold me a car with certain features and they were wrong? If your tyres are not run flats then either ask for full refund on the car as they have mis-sold you the car under the trade description act or ask them for the money to buy run flat tyres!

Post a picture of tyre side wall. May be i can help you

Run flats normally have a star on the sidewall

They will have runflat written on them. Sometimes its written quite small tho

they will have a really small star on the sidewall of the tyre... it's not an x as that is the energy efficiency...

If you have an air compressor handy, just let the tyres down until no more air will come out. If the tyre still looks like it is pumped up it will be a run flat. If it has the classic flat tyre look it will be a regular tyre.

They do have a star on the side yes, they do not have rft on the side though, the lad at the garage said the star just means they are bmw certified or something?

Don't have this wrote on as far as I can see l, just have the small star, I tried Google imaging pirelli cinturato p7 run flats. It's awkward because there is a normal and run flat version of this type but on some of the Google images the run flats have run flat wrote on them. Mine defiantly do not but they have the small star.

The bmw specific Pirelli run flats are supposed to have that code on them

No spare isn't necessarily supplied with runflats, sometimes a tyre seal & inflate kit is supplied - my car spec had either a skinny spare, or an inflator kit, but not runflats.

My tyres definitely don't say run flat on them, damn

RFT is another code seen on the tyre wall.

People often change to non run flat as the ride is better/softer/quieter and the tyres are a lot cheaper.

Spacesaver spare wheels for BMW's go for around £100 on Ebay, usually easy to find.

OK thanks, not sure where this leaves me as I was assured that the car was fitted with run flats when I purchased it, it certainly would have been a stumbling block If it wasn't the case. I'm now annoyed as I've been driving around the country with the potential to be stranded.

There's also the insurance issue as you've changed to none manufacturer specified tyres.....

Was it from a BMW dealer ?

Does the vehicle have a tyre pressure monitoring system ? Are there any warning s?

The set up/handling of the vehicle can be affected if not set up correctly

I would take the car to a local tyre fitter to be sure. On another note I'm actually heading to get new tyres myself today and I'll ask the fitter. Not finish work until 11pm and I'll update tonight.

Just in my local fitters and they showed me the tyre and it does say run flat on the side wall like the images above. They said most people are changing to non runflats on that model as they say the cars ride is better but then buy a spare. On your dealer side of things they said the price difference on the two are cira £350 for 4 tyres, another reason alot of people change. So personally I would be going back to where you bought and asking for the price difference.

Thanks for that, Im going back to garage to pick up wheel off anither car tonight, lad said he would do some research, but I will certainly be going back to the point of purchase by the looks of things.

Oh yea, is probably something you should mention when applying for insurance, the vehicle has a tyre pressure monitoring system yes.

By coincidence, I bought my 118d from a Ford main dealer, who said the same thing. The tyres were not and as they were advertising the car as all original equipment replaced all 4 tyre with ROF's. Only Kumho's, but that was OK.

Perhaps a couple of cans of Tyreweld (dreadful stuff) in the boot until you have it sorted.

Latest update, went to the garage to pick up my tyre, the guy had a look and confirmed they are not run flats, said it's awkward tyre to work out because there is run flats and non run flats in this tyre and both are rated for my car. different brands of car also have different marks to indicate (run flat, rft, rsc,) apparently the bmw specific pirelli cinturato p7 run flats should have rsc on them. My car also has a compressor in the boot. This indicated to the guy at the garage that the tyres were definitely not run flat. The manager also came down he said he has a bmw 4 x4 and everybody gets rid of the run flats because they give a really bumpy and uncomfortable ride. Fairly standard procedure apparently, said i should be OK with the compressor.

My plan is to either buy a space saver or keep a couple of spare tyres in the garage which I can run down the local tyre centre in the boot after using the compressor.

Thanks for all the replies ppl some good info I had no idea about.

Also need to decide how to approach this with the garage, it's not a main dealer, but a reputable local place which specialises in fairly high spec motors. I asked them at least 3 times and was told the car had run flats on.

No, this is not the guy from the garage I purchased the car from, this a a tyre dealer who has nothing to do with place. I was there to have a tyre replaced on the Mrs car and was asking one of the lads there, then the manager, or might be the owner got involved, he wasnt BS ing, means nowt to him.

​I don't see what he'd gain from that as he's not the manager of where he bought the car from but the garage where he went to pick up a spare tyre.

No he's not. RFT tyres are well known to give a poor ride due to the thicker construction of the tyre wall. It is true that lots of people change to non rft because of this. Hence the compressor, which will also need to have a temporary repair kit with it. My wife's Mini has this set up, no rft, no spare, two cans of Tyreweld and a compressor. Personally, I wouldn't do big mileages with this set up (I do 20k a year) as its not 100% reliable, whereas if I get a flat with my RFT's at 3am on the M6 in December, at least I know I can get home!

Yes there's some tyre weld type stuff aswell, all bmw product stuff aswell, which is confusing is i thought these cars came with runflats fitted from manufacture, car has been serviced at bmw thought so could have be added after. I don't drive in the night or do big mileage so hopefully be ok with this setup.i might buy a space saver to use when doing long journeys etc but I suppose if i buy one of them I might as well carry it all of the time but there's no space for one with the car

Stick the last 7 characters of your VIN number (on the logbook) into this website and it should tell you the exact spec of your car as manufactured. Mine shows RFT on the spec.

You sound a bit stressed by all this.
If the dealer told you, hopefully in writing on the ad, that the car had RFT's, go back and ask for what was advertised.
If you are not confident that you can do this or it is difficult to prove, continue as you are, remembering that punctures are relatively rare these days.
If you don't want to lug an inconvenient spacesaver spare, buy some RFT's. They are about 120 per tyre.
Hope it all works out, :-)
