Model 3 has no spare tire
- Thread starter jumper4000
- Start date
Given the demands on the sidewalls to go from folded to unfolded, I wonder how long the rubber will last sitting in your trunk?
That 17" only has a 93 load rating (1433lbs), not the 98 (1653lbs) used by the Model 3, though the speed rating P (93mph) is better than the typical M rating on the compact spares (81mph).

Got a 2017 Maserati Ghibli spare on eBay for $135.
So, there's still no convenient place to put it but at least it doesn't overlap the lower trunk area.
I'm pretty sure if I didn't have a hitch on my car I could cut the metal tub at the rear of the car and fit the spare down there using the space between the tub and the bumper cover though it might also be necessary to cut at the front as well. Rivet and glue an aluminum extension to the area down there and this spare would take up very little space. Now that would be an ambitious project for someone!
- Steel
- 18"x6"
- 114.3x5 bolt pattern
- 0 offset
- 175/75/55 Space Master tire
- 22.5" overall diameter deflated (vs. 26.3" for full size tire)
- 7" overall width
- 39.4lbs
- Does not clear the little bolt that secures the rotor to the hub so that has to be removed before installing (note that the purpose of this bolt is to keep the rotor in place while installing the brake caliper and it is not required).

Is there enough space for it to stand up at the back of the boot or in the lower boot area?
Also would a 17" version fit in the lower boot bay or it it too small?

You can stand it up but it still sticks up a ways. The lower boot bay is only about 16" long so there's no way the 17" version would fit (It's 21.5" inches in diameter. It's too bad Tesla didn't put a place for it, they could have made money selling optional spares!

Nope. There are a bunch of ways that it almost fits! Take out the measuring tape and measure yourself and you'll see. It does fit like this (barely)

Better get out the angle grinder and start hacking away at the tub because that's the only way a spare is ever going to fit. There are 4-5" between the tub and the bumper cover. I didn't check how much clearance there is to the drive unit/subframe when I had the bumper off (and there's no way to remove the lower plastic shield without removing the bumper cover).Have this old skinny VW space saver from my last car - 115/85/R18
It was flat on the bottom of the boot so could do something similar again but not sure what the bolt pattern and centre bore on the model 3 is?
This one is 5x112 and 57.1 centre bore
Yeah, that Maserati uninflated spare was so tempting, but I thought the inflated size was too big, or at least the Ghibli spares I looked at were too big. Yours looks very good. The tire calculator has it at 25.6" which is only 2.7% different than OEM.
Are there any instructions on how many times you can inflate it? Since you have to inflate it from empty to full, I'd want to make sure your pump can run that long without overheating.

Ghibli tire size is 235/50R18 so maybe that's what you saw. From what I gather they can be deflated. Hopefully I'll never have to use it.
Right now I've got two crappy pumps in my frunk. Maybe I should carry my good VIAIR 400P compressor which would inflate it in a minute. Only thing is it uses 30 amps so I'd have to hook it directly to the battery and I've heard about all sorts of problems when you do that on a Tesla (though it's hard to imagine it causing a problem if you only do it for a couple minutes).

One crappy pump with a collapsible bicycle pump for backup.

It's a thin spacesaver so was going to make a plinth where it could stay under quite easily.
However it looks like the centre bore is too small??

Bolt pattern is wrong too. You should post pictures of how you fit it in the lower boot.

5 x 114.3mm for the bolt pattern and bore needs to be at least 64.1mm for model 3

Well..........ahem..............as Johnny Cochran would say, "if it doesn't fit, you must acquit."
thanks, so basically need something like this but for a lot cheaper!

Check wheel-size.com to see what cars have similar size wheels with the right bolt pattern. Then get a salvage spare from one of those cars. Hyundai Genesis and Maserati Ghibli are two that I know of. Some Hondas and Acuras may work too.
