I thought it has been answered.

Otherwise, there are a number of us on the forum running with non-run flat tyres on run flat rims. ...

Yes you can , runflat approved rims were even used in the E39.

The only difference in a little rim on the inside of the wheel that prevents the runflat from slipping off when you loose pressure. Its called a EH2 hump and has been on many many BMW wheels for years, long before runflats were standard

Are those run flat-tires that bad? i mean, is that sound that bad?

Another thing, it is mission impossible to drive on snow with run-flat tires?

runflat tires are very hard. it feels like driving on wooden wheels with no rubber.

driving with RFS or Non-RFS in the winter doeas not matter as far as they are WINTER TIRES. Driving on snow with summer tires = Mission Kill Yourself

anyway, now can a size 225 tire be fitted to 17" style 122 rim (currently 245 size tire)
[snapback]177651[/snapback]
No, I believe the rim is different for the run-flat tyres but is backward compatible so it will take a standard tyre. I think there is an inner lip on run flat rims to help keep a punctured RSC tyre on the rim. A standard rim will NOT take an RSC tyre. The sidewall keeps the tyre up and the modified rim keeps the tyre on.

This is the correct fact. All rims can take non-run flat tires. Run flat tires can only be mounted on run-flat rims. These RF rims should be identified by the mfr. Some, not all, web sites do this.

If those Run flat tires are so bad, the dealer should let us chose which tires to use. All i wanted was sport package not a wooden machine

Naturally, if your car came with runflats, this should apply...if not...then you're fine but I don't know which cars come with runflats and which do not.

I was just replying to this part, you were saying that if the car comes with runflat then you should return them with runflats. The last part you are saying that you don't know how to tell between a runflat and a non runflat tires am I correct.

well so I did some research on our favourite tire shop and here is an answer about the sizes for 17" 122style BMW wheels.

Yes, width 225-245 will fit Good. Now I can order regular non-rf winter tires for those wheels

Love this forum, AKA "BMW specialists Bible"
