Hi EH,
You are welcome
but I am no expert! However, I would suggest that you get a separate set of rims and tyres. Regardless of whether its better to leave the run flats on or not there is always a danger of damage to the rims/tyres every time you take them off. Having a separate set means you can just change them yourself as well. If you are going to use chains a cheaper set of steel rims or alloys for winter also makes sense.
I have not taken delivery of my X1 yet (three weeks to go
) but have ordered the same rim/tyre combination as you. As I plan to take my X1 on some skiing trips I have done a fair bit of research on winter tyres/chains as they are not that common here. I still have to find a set of rims but the official choices for the X1 are 7.5Jx17 and 8Jx18. These are the only ones I am sure about although I understand you can also fit 9Jx18 at the rear. Thats not to say that others will not fit, just that I know these do fit. Also make sure that its the 5-bolt type on a 120mm circumference (thats the 5x120 on the rim). The offset figure (ET34) can vary by 1-2mm but to be safe try and get it at the recommended 34mm. If this varies too much the tyre may rub when you turn or interfere with the suspension.
Anyway, as I said I still have to find some rims but a local dealer can source the tyres for me. So far I have narrowed it down to either Bridgestone Blizzak LM-22 RFT or Michelin Pilot Alpin PA2 ZP. Both of these are available in the correct 225/50 R17 size and can be ordered as runflats.
Hope this helps.
PS: Stick to runflats, you don't want to get stuck in a blizzard with a flat!
PPS: Just seen on a site that sells rims that the spec for a X1 is PCD : 5x120 Offset : 30 to 50 Bore : 72.6. These are on 17" to 20". Surprised by the allowed variation in the offset! Must be due to the large clearance in the wheel arches.
Anyone with more experience care to comment?
