M5 Spare Tire (Wheel) Question - The Unofficial BMW M5 Messageboard (m5board.com)

rhfong1 · 25th March 2005, 02:39

My question is: Will the factory 18x8 M5 front wheel clear the brake caliper if mounted on the rear? I came accross a factory front wheel and am planning on mounting a full size tire to use as a spare but only if the wheel will fit the rear. I was told that this would work but not quite sure. Thought I'd consult with fellow Beast owners. Any help would be appreciated.

Yes! the front stock wheel works on the rear. I have this in my car and had to use it on the rear. I am using a uni-directional tire that has a height slightly larger than stock. I can't remember the exact make or size right now.

Good Luck!

I would like to have a spare tire also, especially when taking the car on an extended trip. I have no confidence in the mobility kit, plus I don't want to deal with all of the gunk that gets inside the tire and all over the wheel.

I have the 15" Brembo BBK in Front and don't know if the stock 18" rim will work, although I have a feeling it will not. I was actually thinking of having a custom wheel made that would fit over my brakes and not take up too much space in the trunk. Possibly a 19" x 5". Could somethig like that work? Does any tire manufacturer make a narrow 19" tire? Something akin to the spare tire Porsche provides in the 993 would be great. A spare that takes up very little room deflated but can be easily inflated when needed for emergencies.

It would be great if there was enough interest that a group purchase was set up for this kind of spare tire.

I'm interested in a space saver spare

I don't know if the non M5 E39's have a space saver spare, but if so, that might be a good starting point.

Thanks Mr Bock. Appreciate your help. Yeah, the wheel I acquired is a factory M5 wheel. Looks like this will work out perfect. Don't like using goop and waiting for the tow truck if it doesn't work. I'm planning on using a Sumitomo HTR uni-directional tire, same size as the original fronts. I currently have Michelin Sports all around. The diameter of the Sumitomo is the same as the Pilot 245/40x18. Happy Easter!

Nope, full size spare on non M e39's. Depending on brakes, the smallest OE wheel you could use would be the 17x8 style 66, which will clear oe m5 brakes, as well as stoptechs. You'd save a little space in the trunk.

I'm also in for any GB on a space saver. The front wheel/tire combo takes up a lot of trunk space, and is not light!

I too would be interested in a GB on a 'real' space saver combo, but untill one is identified, I will keep a spare, jack, lug wrench in the trunk.

LOL

Where did you find it? I too would like to have one around in case (for driving schools and long drives- in case I get a flat and need to limp home). thanks
