Yep. The lip on rims on run flats is different to the lip on normal rims. I don't know whether this has adverse effects or not but that's the tune I got whencI asked about it too.

Belloni · 8 May 2015 at 09:52

Hmmm that sucks, I want normal tyres!

Sorry, I'm backing out as I have very little experience with E-SYS on F series. As you were.

Fitting normal tyres is absolutely fine.

That sounds like BS to me.

It's not, but it doesn't affect the possibility of fitting regular tyres.

Is there any risks to fitting normal tyres on a RF rim?

Diddums · 8 May 2015 at 16:56

Oh sweet, thanks for pointing that out. I'm on the verge of getting a new set and have been sitting on the fence about run flats for ages now. Might just bight the bullet and go for regulars with a can of foam in the boot.

Picking up the ancient E36 tomorrow

144k miles, I bet it feels like brand spanking new

Should be a hell of a wake up from my Jag!

I meant being told you can't fit regular tyres.

toasteh · 8 May 2015 at 22:45

can confirm. MINI came with runcraps, fitted regular tyres no problem. The rim situation is like petrol/diesel nozzles as i understand it, you can put regular tyres on a runcrap rim but not vice versa.

Runflats will physically go on any wheel....it's just a bit of a stupid thing to do

I asked about putting normal tyres on, the guy didn't recommend it. He said something about the rim lip not fitting?

You'll be surprised just how little tyre fitters know about tyres. They know how to put them on an alloy and take it off, sometimes they can even balance them first time and not damage your alloy too!!

Why's that? There not really any meaningful difference in the bead and rim between RFT and normal.

growse · 9 May 2015 at 20:05

One of the small issues I overlooked when recently getting my E91 was a little bubble on the climate control panel:

Does anyone know if this is an easy thing to sort out? It doesn't really bother me, but it'd be good to know if this is a quick/cheap fix or something a bit more major.

mrk · 9 May 2015 at 20:06

Remove the trim and respray it?

It's bubbled because someone had a vent air freshener which leaked.

The rim of the wheel and bead of the tyre on a run flat interlock so that the tyre doesn't come off if it deflates. Non run flat rims don't have this so the tyre can come off.

rodenal · 9 May 2015 at 21:18

The above and the fact that without pressure sensors it's much harder to tell a deflated runflat with the crazy stiff sidewall, till the car goes sliding around
