Changing from RFT's to 'normal' tyres - Pressure question?

[moffat]

Hi everyone,

I don't really want to get into the debate around RFT v non-RFT pro's and cons, but I am changing the tyres on my 2014 640d from the 20" Dunlop Maxx SP's to Yokohama Advan Sports and supplementing with a BMW tyre fix kit which comes with M cars.

My key question is what pressures would I need to run at and how would I find out?

I imagine that it's not the same as the RFT's but I might be wrong??

Any help appreciated!

I run mine at the same pressure as the Rfts in my E90 335i (34 front, 36 rear)

I agree, with Dann.

I did experiment with different pressures, even took advice from the tyre manufacturer, but by far the best were the pressures I used for the RFTs. as per the A pillar.

I changed to Michelin Pilot Super Sports if that helps.

And by the same principle, when I put my winter tyres, on and changed the wheels to 17s (from 19s) I've also followed the advice from A pillar.

Great - thanks guys, that's a relief!

Looking forward to getting rid of the jarring, skittish ride

I have a 640D GC and have Continental's non run flats and use 2.4 front and 2.6 rear.

A major transformation from the Dunlop run flats.

Thanks

I've ordered Bridgestone Potenza S001's from TyreLeader, two have arrived and just awaiting the other two so will get fitted next week. Looking forward to having some decent rubber for the winter!

My local tyre place has offered to keep a hold of my current tyres as except one are all fine (I previously had a puncture on a rear).

Review to follow.
