Just got an 05 ZHP sedan and it has a space saver spare.
I’d like to carry a full size spare, as I routinely drive 350 mile round trips in the wilds of Eastern Washington where services are few and far between.
The 330xi I’ve had for the last 7 years came with a full size, 17” spare, and it’s actually a very tight fit to get in and out and clear the plastic trim.
I don’t know if it would be even worse with 18 inch wheels with wider tires.
I’m running stock 135s.
What do you all do for spare tires? (That will fit in the spare tire well, LOL)
