That's not actually true. The rims are runflat specific - but you can fit 'standard' tyres. If the rims did not have the EH2 hump then you can't fit runflats tyres because they could shear off the hub when running flat.

However, back to the issue. Go and ask the dealer how the factory-fit non-runflats 172M option works then!

There's also no legal requirement in the MOT to have runflat tyres, even if fitted as OEM. As long as the tyres are suitable dimensions and, if there, the spare is legal.

 

Thanks for the clarification -- the point is, and I'm glad you agree, that there's nothing about the rims that would prevent the proper installation of non-runflat tires (or to be ultra-clear for the UK folks, "tyres!")

 

Indeed, highly recommended too!

 

Thanks coleji - had to have the tyres replaced for the MOT due to sub-2mm tread and dealer spun me the "new rims" yarn so I had to go ahead with the runflats.

Will change the tyres to non-runflats either when I've scrubbed the new ones I've just had to put on or when I'm feeling like spending a few quid, whichever is the sooner. BTW does anybody know if the spare whell bay in the boot is physically big enough to take a full size rim and tyre? I really, really hate those spacesavers.

 

The proper answer to your question is, no, the wheel won't fit. The obtuse answer is that yes, a full size spare will fit, but you will have to do without the complete boot floor!!
As far as the spacesaver goes, I don't think anybody likes them, but I will take that option rather than going back to the awful RFT's. If you leave the boot undertray in place, the storage dividers will have to go, and also the slots in the undertray will have to be pared down with a craft or Stanley knife to make the spacesaver slip in better. If you don't want to do that, then just lift out the undertray and put the spacesaver in the well. You can go to your $tealers for a new wheel and jack kit for around ?170 I think, but you can also source the wheel and tyre from your local tyre fitter (but probably not Kwik-Fit!!) Mine was ?85 for the wheel and tyre (wheel a genuine BMW new item, and Continental tyre). Wheel braces are around ?4. I modified an old Vauxhall jack to slot into the BMW recess - the modification took less than 5 minutes with a Junior hacksaw onto the plastic top!

I presume although sub-2mm they were at least 1.6mm?

 

Is it OK to fit non-runflats on one axle while I wait for the remaining tread to wear off my existing runflats? Are there any sensor issues if the sidewalls give a bit more and effect the rolling radius?

 

You can but it's not recommended...

 

Only just legal - but in fairness the car's done almost 40,000 miles, some of them quite, erm, exuberant since I bought it so one new set of tyres isn't too bad really.

Anyway, I have a bit of a thing about tyres being in good condition as I tend to drive, erm, exuberantly on the twisties and occasionally drive at > the UK national speed limit (only whilst abroad on unrestricted roads, obviously )

 

Just an update. Fitted my rims and non-RF tyres, reset the IDrive Monitor and all is well! ... SWEET!
