Ditched the runflats

[gavsadler]

Well I decided to bite the bullet and try something different.

I organised a space saver spare wheel to carry in the boot, and I've fitted Hankook Ventus V12 Evo's. 225-40-18 all-round.

So far initial impressions are good, but I will wait for the tyres to scrub in a bit before pushing things a bit more.

I've read elsewhere that if you fit normal tyres, you need to pump them slightly harder than the runflats? Is this true?

Currently my pressures are as follows:
Front: 2.3Bar (33PSI)
Rear: 2.6 Bar (38PSI)

What pressures would you recommend? By the way, I've fitted 225-40-18 all-round. I will post pics when I get a chance.

I haven't yet bitten the bullet myself and ditched the RFTs, but I would think start with the default tyre pressures and see how it feels. I know that the 1's are very hard with the RFTs so I would think the non-RFTs would be a lot more compliant and ideal at the normal pressures. You also don't want to wear the middle of the tread out more by making them too hard. The Hankooks are on my short list for non-RFTs to fit so I am very interested to hear your impressions and experiences with them as they wear in! :thumbsup:

could stand under correction but i wanted to try to change from RFT's on the 130i and was told by bmw that if i did it would affect the motor plan. i mean the price on them are unreal.is it true. due for new tread at the back and got perreli on the back and good years on the front. at the time had to replace could find stock to match the same all round.

That's their usual utter nonsense - for piece of mind go to another agent and ask them if it is okay to use non-RFTs and the space-saver. There really shouldn't be a problem with the motorplan, just the roadside assist in terms of having a puncture on the side of the road. Try and get something on black and white that the use of RFTs won't affect the motorplan - how can the use of non-RFTs negatively affect the rest of the car...

But the other important thing to do is confirm with your insurance that this isn't a problem since it is considered a reduction in safety in the event of a tyre blow-out - extra risk. So also get something on black and white from them indicating that they are aware of this and okay with it.

I changed to non-RFT a year ago. Best thing to do. The ride and handling is far better than RFT.

Pump the tires 0,1 bar more. The pressure guide is for RFTs. So do 2,4 and 2,7.

I fitted Conti's 225/40 R18 and 245/35 R18.

Which Contis? Contact Sport 3?

 

[3V0M-WP]

Yeah

 

[Philip Foglar]

Okay. Quiet, don't tramline, and wear up until now?

Thanks for the responses, for now I'll leave it as-is and see how it goes. Then at next fill-up, i'll check pressures and adjust if necessary.

One thing I can say is that speedbumps are no longer the menace they used to be. They are taken care of with much less jolting and crashing about:thumbsup:

Okay, that would make sense - my 330i would have a slightly smoother overall result to the bumps with RFTs, at least I have heard that the 1 Series is quite a bit bumpier with the RFTs than the 3. Anyway, I have had a few occasions when I have gone over some bumps and the car literally loses grip as it jitters along! Quite unnerving! Then the other thing it does is tramline - sometimes not too bad and often one almost forgets that it has this problem, but, for example there is a piece of residential road where plenty of trucks have been pounding along and as a result there is this nasty tendency that the car suddenly wants to veer to the right and into the isle! I mean if you aren't firmly holding the steering wheel I reckon it would take the car onto the curb! No thanks!! :shocked:
