Questions regarding 20" wheels
Hi,
I have a few noobish questions regarding an upgrade to 20" wheels. I current have a 19" square setup on my 21 M40i with Conti. ExtremeContact DWS 06+ tires. I've been curious about 20" wheels in a staggered setup and want to venture in to getting some lived experience with them. I'm contemplating moving to a 695 tire+wheel set this Spring once it starts to get warmer: https://www.shopbmwusa.com/product/6...SET,-STYLE-695 However I'm unclear about the reality of a staggered setup like the one above which comes with perf. summer RFTs in a Front / Rear: 245/45 R20 103W / 275/40 R20 106W config. Questions below --> - As per my understanding a staggered setup like this benefits from better handling(e.g. while cornering and better traction in the winter with appropriate tires). Is this accurate? Because after scouring the forums what I see is that a lot of folks run this setup in the summer but prefer 19" square setups for the winter. Apart from the uneven wear of the rear tires compared to the front, is there a reason why a staggered setup like this would not be preferred over a 19" squared one? - If I get the 695 tire and wheel set linked above, I plan on running them through the summer and then replacing the tires with good A/S tires and running them year round from there on out(either Conti. DWS 06+ or Pilot Sport A/S 4). I live in the PNW and don't really need a dedicated winter set. So a good high perf. A/S would be ideal. However should I keep anything in mind in doing so on such a 20" staggered setup vs 19" squared? |

I run staggered AS and Square winters - usually with the smallest rim to allow the most rubber and subsequent pot hole protection. Put spacers on the rear to keep the rear "look" going...

This gives me some more to think about. Because ultimately what I would end up with even if I do end up trying out a 20" staggered config. would be similar high perf. A/S tires on them for year round driving. |

OP: Sounds like you don't need a set of dedicated winters where you live. If I were you, I would sell the 19's and get a set of 20's with the same Conti A/S tires to run all year long (that's the setup I have). |

I couldn't find that as an option on the accessories page once I put in the model as 2021 X3 M40i. |

Seattle area here as well. I sold our 19" 698's and put on a staggered set of Beyern Damon 20's with Conti DWS06 Plus. So far so good. Also have the Conti's on my SQ5.

Front / Rear: 245/45 R20 103W / 275/40 R20 106W You'll probably need to go after-market to get a square set of 20's. |

Also in Seattle, running staggered summers and square winters on my 2 series, will do the same on my X3 as soon as it arrives.
If I was going to run all seasons up here I would probably just go staggered. Also I have observed over the years that my tire wear front and rear is not different enough that I would care to rotate them when square, since I tend to replace winters every 2 years anyway (well, far less often now that I work from home every day.. I didn't even bother to take the winters off last summer and they are still good for the rest of this winter and then some). |
