Before I pull the trigger, question on wheels/tires on e50
Hello everyone,
this is my first posting over here. As I'm about to pull the trigger on an e50 (config here), I wanted to address a topic I'm not very familiar with: wheels and tires. I've seen in the following thread that 21" are to be avoided due to difficulties to get the right tires. Could someone give more explanation on this? My preferred 22" designs right now are 747M and 742M bicolour but I want to make sure I find the right balance between driving comfort and tire nightmares. Note that I'm in Belgium, in case tire sourcing depends on country. Thank you |

I'm not sure why the 2 people in that tread mentioned lack of options because the 21" tires have much more options than the 22" tires.
If you're looking for more comfort, then I would suggest 21" tires that aren't RFT. 22" tires pretty much have 3 options for summer tires and 1 option for A/S tires. Pirelli's, Conti's, Nitto's are the only 3 brands I'm aware of. |

If you want to increase sidewall profile(No problem reported with this setting so far), then there are multiple options. |

I have 22" 742" on my 45e and I choose them again on my 50e. No complaints concerning driving comfort and availability. The car looks best with 22".

Likewise for the 22" tires. Only 1 A/S tire available and 3 options for summer tires. For 21" summer tires, I'm confident that there are more than 3 options, although I haven't done any research myself

The larger the wheel, the less sidewall to cushion things. How well a vehicle rides is dependent on the tire/wheel selection, the suspension, and the quality of the roads. Many feel that looks may override any other considerations and feel a 22" tire versus a smaller diameter is required on the X5.
Choosing a RFT versus a normal one is also a consideration. A RFT's sidewall will be stiffer to be able to hold the vehicle up safely if it loses air. From what I've seen, at least in the USA, not sure about elsewhere in the world, the only non-RFT options on the X5 are summer performance tires, which often may require two sets of tires to accommodate the cold. That can also limit your tire choices. Some places outside of the US may also require that you purchase a BMW approved tire to retain your warranty, so you need to check on that prior to making your decisions. As you go up in wheel size, the market is smaller, so fewer and fewer options are available. Getting the BMW star o a tire is more than a marketing ploy...the tire manufacturers and BMW work together to optimize the tire design for that specific vehicle. This is not to say some other choice may not work, but it may not have the attributes BMW chose as important. That may not match up with your priorities. Note that if you drive where tire chains may be required, BMW does not allow them on 22" wheels. What you do is up to you. Personally, I have 19" wheels on mine with RFT, and it rides decent with the air suspension. I've not noticed a lack of handling capacity for the way I drive. I cannot see the tires/wheels while driving, so looks aren't a big deal to me. I've owned some less than stylish vehicles over the years which follows that thought as long as they function well. |

I think the limited option comment only apply to those want to replace factory summer tires to all season tires. If you are ok with summer tires, I don’t think choice is an issue.
In my case, I need all season as it is family go everywhere car, so I opted to 20 only. But I do love 741, 742 and 747. All are beautiful. Last edited by eelnoraa; 06-08-2023 at 12:44 AM.. |

Are you sure? I did European delivery twice, both in Winter time (Dec and Jan), both cars has summer time in them. If it was legally mandatory to have winter tires,, bmw won’t let me drive them out of their factory, right?

There are probably at least 5 different 'classes' of winter tires that optimize things according to different parameters such as:
- high performance, may not be great in ice or snow, but handle the cold well - Nordic winter tires, work best in ice and snow covered roads, okay on dry roads - intermediate between the above two And others, optimized for different conditions. So, characterizing all 'winter' tires as the same is both wrong, and may not give you the best and safest situation for your use. Because the winter tire's rubber is softer, it could ride better than a summer tire that partly relies on the heat to keep the rubber flexible so it can provide traction. It usually is a bit noisier, but that depends on the optimization. |
