The f10 doesn't have crazy low profiles. Even with 19's, the fronts are 245/40. The rears are 275/35, but that's .35 of something as wide as a steamroller. I've not had tire or wheel damage (other than light curbing) on that car. Non runflats don't damage very easily (see my next post). Last edited by equ; 02-28-2019 at 12:13 PM. |

* reduce performance, especially with bumps involved * ride worse * have a higher fault/bubble rate My experience with frequent bubbling (2007 through 2009, until l fully gave up on them) is corroborated by comments I've read from a tire engineer who said that they have been great for the bottom line. High prices and frequent replacement, what's not to like? It's simple for me. Every time I get a bmw, I get rid of runflats asap. Fortunately, this one didn't come with them. I still have to go through my usual second step of "building" a spare though. For the f10, I skipped bimmerzone and for less money, built a spare with an OEM alloy beautiful emergency wheel. The 340i track handling is less lucky with its 18" minimum, I cannot transfer that nice spare I built. So I've ordered an 18" steel wheel (X5 size), centering rings (74.1 to 72.6) and a 145/70/18 from Tirerack. |

I haven't driven a Mark VII GTI (have I?), so I can't really compare. It seems to me, though, on any setting other than stiff the car has a weird, not quite right feeling to it; like it wallows too much. Maybe there is a way to tune a suspension so that each of the various different options feels "right" with the rest of the componentry. I just haven't found a car yet where that's the case. |

I also ordered the tire but it's pick up from Tirerack (so I could easily cancel). Yes, first time picking up from Tirerack. I wouldn't have bothered for saving $18 on a $120 spare tire, but I'm also buying a winter set where the savings become significant. $100 in taxes (yay, Delaware) and -$80 shipping refund, so I'll drive 100mi each way to save $200, I have a new car to get used to (that I don't drive to work or anything) and not a lot planned for Saturday morning. I'm attracted to the idea of saving a few bucks, but between 10-yr old and that stretch, I think I'll just buy the new tire. If it's both tire & wheel, that's a lot more attractive, but I'll have to return ship a wheel. Sucks that I can't use the beautiful f10 spare, much nicer, lighter wheel. I was almost going to try it with spacers just hoping. Apparently, not even every 18" wheel apparently clears the 14" calipers so I'm passing on that exercise - I also don't have spacers and long bolts at the ready. |

This is a nice 18" wheel, I just saw it through your bimmerfest links. Didn't know about it and the 0.5" narrowness would help a bit... Though at $236 over the $86 I'm paying for the steelie, I'm not sure if it's worth it. Looks just like the nice one I have for the f10:

But I had the same X5 steelie that you did, and I didn't think there was any issue with the stretch. Check those pics in the thread I posted; it was really not that bad looking. Happy to send the tire your way, but you're probably better off buying new. |

Equ, how do you secure the spare in the car, the way bmw did it on the 5er is to raise the entire trunk floor. I never use the trunk so it doesn’t bother me that there is less storage but I can see it might bother others.
