First of all, the 442M is a 19" wheel: http://www.realoem.com/bmw/showparts...89&hg=36&fg=15.
Second, you can compare the offsets and width to the 18" (for the minimum) and the 19" (for an equal) of the F15. 18" 446 wheel for F15: http://www.realoem.com/bmw/showparts...20&hg=36&fg=15 19" 467 wheel for F15: http://www.realoem.com/bmw/showparts...74&hg=36&fg=15 The 18" (the lowest you can go on an F15) has 8.5X18 offset 46 on all 4, while the 19" 442 wheel from the 425i has a staggered 8x19 offset 36 front and 8.5x19 offset 47 rear. The 19" F15 467M wheel has 9x19 offset 37 for all 4. Technically, it's possible, but is it recommended? Not really, unless you do the rear wheels of the 442 as a non-staggered setup meaning 8.5x19 offset 47 for all 4 wheels. The 442 center bolt pattern is 5x120 just like the F15, however I could not find the center bore size. If it's anything less than 74.1mm, then you will have to get all four wheel centers shaved to 74.1mm in order to fit on your X5.

Opasha Wise One... Question?
Hi... I'm new to the board, so I apologizes in advance for my newbie questions.
I just took delivery of my 35d 2015 X5 M-Sport today!!! Loving it already. The 20 inch wheels (perelli's p-zeros) are staggered run flats. Also there is the Tire Pressure Monitoring system as well. I want to replace the summers that it came with with all-seasons. The CA was trying to convince me to buy a set of 19 inch tires/rims etc, but I would rather just have all seasons. I can find the staggered set of tires in my size, but none come with Run Flat. I want to buy these non run-flat tires, but worried this might mess up the on-board computer and start throwing out error messages or problems. When I read the manual... there does seem to be some form of flat tire sensor on top of the TPM system too, but not sure if this really is connected directly to the tire itself, or just the pressure in the tire??? My question is... can I buy non-run flat tires without causing any error or on-board computer issues? Thank you!!! New Guy. |

Those who replaced their RFT with non run flats, did you all go with the spare tire ? I'm asking because I don't like the stiffness of the RFT, but I'm worried about getting a flat since I have no spare tire. I have the third row seats.

I ordered mine with spare tire. I was going to go with 3rd row option until i found out that x5 can't have both 3rd row and spare tire configured. I decided to skip 3rd row option. Hard decision but I already got a minivan for 7 passengers. |

As others have said and this includes me, you don't have to use RFTs. Non-runflats work great. Sure, if you're super hesitant, you can buy a spare tire kit. The car actually will ride better without vibrations since RFTs are very noisy in general.
No issues will occur with TPMs or the onboard computer . PM me if you want any advice on cheaper tires. My Delinte D8 All-Season tires are running great. PS: I'm not the wise one. There are plenty of knowledgeable and smart members on here that know plenty about our vehicle .

My winter tyres and wheels are not run-flat. If I have a puncture I have no spare, just a repair kit. If this fails then it is recovery call out. The other thing to consider is actually changing the punctured wheel on a public road. I would suggest that it is almost impossible to do safely. I have a professional trolley jack to change summer/winter with chocks and axle stands in my garage. The thought of trying to this with a 2 tonne vehicle on a road that is probably not dead-flat is almost beyond belief. I've also never had a puncture in 37 years of driving so do you need RFT?

If it makes anyone feel any better, my Delinte D8's got a shard of metal (looked like a big melted nail) in the outer most inner tread area and I drove for three days without realizing as my PSI slowly decreased to about 30 for the back right tire about 6 months ago. I got it patched (cost me $15) by my tire shop. It has been running great without any air loss or issues ever since. I'm content with my choice.

Insurance ONLY covers BMW OEM wheels/tires (run-flats), so I think he's good with his decision as are many of us. We had that insurance for 3 years (~$1800) on our 2011 x3 and never used it once. This decision will ALWAYS be 50/50 for everyone. Everyone's experiences are different and what they have seen/gone through influences their insurance decisions greatly.
