Like what the subject says. Just wondering whether anyone new if the tyres supplied on Monza II wheels were run flat or normal Bridgestone Potenza RE050 A. I have got a defect in one of mine and VW say they can not locate one as they are run flat, just wondering if I can get one else where as I can not really run the car just in case.

Since the car comes with a spare I would think they are not runflats. Try going onto the bridgestone website and putting in the full code for the tyre.

Another thing to try is to let all the air out of a tyre. If it is a runflat it won't look totally flat as the stiff walls in runflats keep them up (oooh matron!). That is how you can continue to drive them.

I hope they are NOT RF as they will be about ?200 each to replace if they are and amny tyre fixers will not fix a puncture in a RF as that is what the manufacturers guidelines are. No reason they can't be fixed - just a scam of course !

From my experience, yes. My GTTDi is fitted with the Bridgestone Potenza RE050's and when I for unfortunate enough to pick up a puncture and had to source another tyre I was informed they are run flats.

Very few people keep hold of them (circa ?200 each) and it took 3 days to get hold of mine via Kwick Fit, they distroyed the wheel whilst fitting it, but thats another story.

I am very surprised the stealer or handbook does not state that they tyres can ran flat with certain conditions (speed, distance etc) otherwise people will never know!

There really should be a section in the manual if they are runflats. There will be a spec like max speed you can drive at and for how long etc.

Just had another thought. Could it be that only cars fitted with the optional tyre pressure warning system have runflats? I know that the MINI can come with runflats (all 16 & 17" tyres) and they have a tyre pressure warning system.

BTW everyone with MINIs hate the runflats as their performance is crap and they give really bad ride quality. Magazines are always slagging off BMW's with them too.

Oh and another thing! A lot of tyre places won't replace them as they know they are a b*tch to get off and fit so are likely to trash your rim!

Are you sure the RE050 A's are runflat? I thought the RE050 had to end with RFT to indicate that they are run flats?

I would have thought VW should make this obvious if it is the case.

JamesR, are you sure yours are run flats?

I am hoping they're not, as it's the last thing I want on my new GTI! Here's hoping they're not!

Spudboy,

I thought the same as you that it should have RFT on the sidewall, but been to check with VW as I have slightly defective tyre and they did some checking and according to them they are Run Flat and are having trouble getting hold of them. The car has tyre pressure sensor on it so they can only do this with run flat.

Still waiting for them to get me a new tyre and then I can tell for sure what is on the sidewall and post sometime soon.

If you can let us know, that'll be useful. I do hope they're not run flat.

As for the pressure monitors, a friend of mine has a Renault with them, and I know he doesn't have run flats, so this makes me think these are not always connected.

Anyway, it seems to be a mystery to us all, so let me know how you get on......

Hi,

I had runflats on my Z4 - didn't like them much to be honest - strange ride quality. Anyway, like all BMWs with runflats you didn't get a spare. Do you have a spare in the GTI?

If you do - why?

I think I may be tempted to ditch it in favour of more storage space.

Chez.

ZMan,

Yes they do have a spare either space saver or you can choose to have a full size wheel.

It all seems strange to me as I have to get one of my tyres changed as it is faulty took it back to VW who would not touch it as they said the machine they have does not have enough pressure to put the new tyre on. The wheels also cost ?385 each so nobody wants to touch them.

Anyway as it turns out I get a call from the dealers as I had also showed them marks on the alloys, and now I am getting all 4 alloys replaced under warranty. So wait for alloys and the new tyre plus the others will be fitted by a specialist.

On tyre pressure systems there are two ways of doing it I believe.

A) Some pressure sensor in the tyre - seems complex and scary for the likes of Kwik-Fit.

B) MINI/BMW system - the ABS systems monitor the rotational speed of all 4 tyres. An underinflated tyre has to rotate quicker to keep up since it's diameter is less.

Don't know what is in the Golf.

I still do not believe the Golf has RF tyres. I had a look at the bridgestone website and the code for RF's ended in something like "RFT"

Kenl,

From what I have read in the manual, it uses the ABS system.

Like you I don't fully believe that they are run flats, that is why I posted, and I am trying to find out. Fortunatly this tyre I need now is being sorted by VW along with new alloys, but what happens if someone replaces a tyre due to a punctune they could put the wrong version on.

I will find out as soon as I can and let everybody know. I would expect to see RFT on the tyre if it is run flat.
