new to RFT's

hems77 · 07-20-2009, 07:07 AM

Hi everyone

I just picked up my 07 plate 320d M Sport last week. The car is great, been looking around for a while and got a good deal from a dealer.

This is the first car I've had with run flat tyres and don't know much about them. I'd read before the ride can be harder and you feel everything on the road - I have noticed this but it doesn't seem too bad. The car has Michelin Sports PS2's.

After reading a few posts (I guess I could do some more research) my long term concern is wear and costs. From what I have read, they are really expensive to replace.

I just wondered what realistic wear and life will I get out of them and how much would I be looking to replace each one?

Does it make sense in future if one of them goes to change them all to normal ones? If I did I'd be without a spare wheel too.

Any advice/experiences would be helpful!

Thanks very much!

If you're on PS2 staggered 18's, then the rears are about £250 each and £200 each for the fronts.

I used to drive my 330i fairly 'robustly' and the rears did 25k with about 3mm left on the fronts.

I still changed all four at 25k, and then went to non-RFTs come sell on time at 50k.

Got 24k out of mine, with the fronts still legal. Moved over to non-RFT due to the better ride/handling.

DIDNT even read what your prob is.. No offense..

BUT GET THE RFT's OFF THE CAR ASAP.. You will feel like you bought a new car TWICE!!!

thanks for the replies guys.

sounds like i dont have too much to worry about. was just concerned and probably a little scared from what ive read and heard so far.

i asked the dealer too and the chap just said the car with the rims I have (18s) were designed for RFT's. it gives better ride and handling. sounded like bit of a fob off.

they also mentioned some tyre insurance for covering the tyres against puncture/replacement etc for 2/3/4 years. any one had this from a dealer? is it worth it?

thanks again

It is.

The rims are .... rims. The RFTs are shi*te.

Indeed, there is no such thing as a RFT rim. They are all the same.

Not quite I believe..

A wheel designed for use with RFTs has much higher internal bead seating ridge to stop the deflated tyre bead coming off the rim. A normal wheel relies on air pressure to hold the bead on the seat.

So you must have an RFT rim to fit RFTs, but an RFT rim can take RFTs or non RFTs.

A standard rim can only take non RFT's.....

Thus we have the pleasure of choice... we can fit either type on our wheels.

phew.
