Well the time has come round for a new set of rears and I'm just wondering is it worth getting rid of the RFT?

Would I need to have the sensors programmed out? I don't have a screen only the obc.

Thanks

[Russ.C]

I do recommend moving away, If you do change from runflats then you should do all 4 as it's not recommended to only change 2, no sensor coding out as it works out the tyre is flat by looking at the time for the wheel to do one rotation compared to the other.

It's the best upgrade you will ever do and it saves hundreds of pounds purchasing non run flats! It's a non brainer!

Non fun flats on the rear and run flats on the front will be no problem, it's a not recommended to mix them up on the same axles.

[Jase 320d]

My local place wouldn't fit non rft's to the rear while i still had rft's up front.

Apparently the rear washes away if you run rft's upfront with non rft's on the rear.

Id change all 4 personally

You may save some money, but not hundreds.

I would change all four rather than mixing RFT and none RFT on a car.

Oh well, their loss. Absolutely no difference in grip between RFT and normal tyres. I'd change all 4 too, and sell the part worns on ebay or on here - but there's no issue with having them on just one axle.

I think its more to do with sidewall stiffness

What do you lot do if you ever get a puncture?
Ive thought about doing these to try and save my poor kids in the back as its a very bumpy ride snd even worse back there

[adamroutley]

I have non- RFT on the back and RFT on the front. No problems what so ever and have been on for about 2 months.

I have a genuine BMW inflater an genuine tyre weld should I get a puncture.

[Jase 320d]

do you push it though....

The rft can take higher cornering speeds as it stays flatter to the road as there is very little sidewall flex. A non rft will break away earlier as it has more give in it.


Well thats what i have been lead to believe

[Wrighty_QPR]

Have always stuck with RFT as saved many a time stuck on the m3 in the cold and dark!

Never noticed that much of a price difference either.....about £40 difference? Would happily pay 40 quid to let me get home rather than stranded mucking about on the side of the road.

I was wondering what the neatest setup would be when using non rft. I bought my car from a guy who's fitted continentals but I don't have a back up plan at the moment if there's a flat!

Stiff sidewall will break away sooner but more controlled.

Soft sidewall will hold on longer, but break away more harshly.

I have RFTs on the back, nons on the front, front has a huge amount more grip, back end loves to step out of roundabouts if prodded, DSC goes crazy.

I have RFT's on the back. Michelin ZR's and Non RFT's on the front. This after 10k is a lot better for me. No tram linning or pulling from the front. Handles better also. I'm sure it might handle slightly better with NON RFT's at the back also, but i carry no spare wheel.

That is what the garage told me.


Said he wouldn't put non rft's on the rear while i had rft's up front

Now I am really puzzled, on the tech forum post MIXED TYRES you say mixing tyres is stupid idea?

[E30 sam]

Thanks for the replies. What have you guys done about having no spare? How much are the compressors and tyre weld stuff?

Thanks
