Replacement Spare Tire.

[L84THSKY]

Hello

My spare is ruined from deflating and having it sit behind my modified diff. I tried to order a new one, no luck. My question is, what size tire and rim that is available today is a good substitute? I'm talking about a donut, not a full size spare.

Thanks
Eric

Hello

My spare says 125/90/15. Spoke with Tire Rack, they don't carry that size. Even BMW can't get it. Any alternate sizes that fit the lug pattern and circumference requirements.

Thanks
Eric

THat sucks thats where I got mine (A couple years back) its a Continental..

Check with a Ford dealer:
Firestone Radial Tempa Spare T125/90R15 fits 1994-2004 Ford Mustang

It would probably be easier to find a whole used spare wheel/tire that is in better condition rather than trying to find a tire for it.

[L84THSKY]

I don't care if I buy a wheel with tire or just tire. Just need something that fits.

TOugh part is when I was looking that if you find a used tire and wheel its as old as what we have now..

Continental T125/90R15 are out of production since 2010 and all of them have now been sold out of the system. Continental found the last few in an Ohio warehouse in 2013 and I got one of them for $140. I have my old one for sale:

2002 Z3 came with a 125/90-16 space saver spare. You can still get that size tire at tirerack, it has the correct overall diameter (24.9") for the 318ti. Looks like you can still order the wheel from a BMW dealer.

[spidertri]

He asked several times for a substitute wheel/tire combo that is available new today. I merely provided an OE option.

Plus even if he doesn't want it someone else might search for the answer and could use that information in the future.

Good luck selling your 17 year old tire.

Thanks for the well wishes on selling the old tire. I wondered if I should have gotten it, after being unable to tell the difference between old and new.

[Coyoteh]

The overall diameter of the tire itself will be 1 inch greater, so will it still fit in the spare tire carrier?

[vintage42]

And what will the extra diameter do running on the car? Might it harm the differential?

According to a tire size calculator the diameter is actually pretty close to our full size tires (but our stock spare size is smaller)

Stock full diameter: 24.7 inches
Stock spare diameter: 23.9 inches
Z3 spare diameter: 24.9 inches

[spidertri]

Yes, the outside diameter of a 125/90-15 is 23.9", this is an inch less than a normal 318ti wheel. So technically, if you're going to "harm the differential":rolleyes: it would be when you run the 15" spare. :eek:

125/90-16's overall diameter is 24.9".

Stock 318ti sizes

205/60-15 overall diameter 24.7"
225/50-16 overall diameter 24.9"

Yes, I said he would need to get a new wheel, I even provided the part number. It is $35-$50 depending where you get it from.

I don't know if it will fit perfectly in the tire carrier. Potentially you could modify the stock carrier. You'd have to make sure there was 0.5" clearance to the tightest spot on either side of the wheel. Or just stick it inside the car for longer trips with a wheel cover on it.

[spidertri]

Good call pointing out the carrier dimensions Coyoteh.

Tirerack has a 125/80-16 kuhmo spare tire for $65. That overall diameter should be 23.9" which should fit nicely in the stock carrier.

Pick up that and the wheel itself (p/n 36116750006) from a BMW dealer and have a nice new spare.

Has anybody tried a full size tire in the spare tire compartment under if it fits? What needs to be done to make it fit?

i was wondering this as well as my ti came with an amp in the spare tire well :-/

Has anybody yet tried this recommendation from Spidertri?

I had to use my 17 year spare. Was the only option I had. Was cracked. I slapped it on and limped to a service station to inflate. Then drove at "reduced" highway speeds for about 40 miles.

car sat on spare a week (not driving) and I got all new tires and threw the spare in the hatch till I could find a new one. Had a run of warm weather and check out what happened! (pic's below) Glad I wasn't in the rig when that thing let go!

Anyhow I'm going to try this idea and see if it'll fit, wondering if anybody else has yet.

[BlackBMWs]

JB Weld should fix that right up. :rolleyes:








Seriously, I also should check my spares... :cool:

[juice2000]

The spare on my 95 ti didn't hold air anymore. Bead seal didn't fix it, most likely due to corrosion on the rim.

I found a spare on ebay purportedly from a 2000 Z3 that was sized the same (T125/90/R15) and looked like an exact match. It fit perfectly. Apparently some Z3's came with a R16 spare and others an R15. Hope that helps someone.
