Hi forum members.
I'm hoping to get my first Tesla Model Y in a few months but what irks me is that there is no spare tyre like an older S model. I have an idea of a possible modification to store a spare tyre in stead of the under-trunk well. However, I need to verify if this is possible with the help of this forum from someone who actually owns a Model Y and to hear your opinion.
I understand that the actual bin is too small to hold a tyre. In a post on this forum @halfricanguy shows pictures of the trunk after removing the mat and the attached under-trunk well. The space is much bigger than expected.
Another youtube video posts how to lift the mat from the back (towards the bumber) which seems easy enough. Forget about him teraing apart the rest of the car in video.
In the Tesla Model Y manual it is stated that the loading in the undertrunk can take up to 130 kg. So this should definitely hold up
My thought is that if one cuts the undertrunk well away from the rest of the floor lining, would it be possible to put a spare tyre flat down in the hollowed out section and still be able to cover it up so the boot space is flush?
I doubt a normal 20 inch tyre with its 28 inch in rolling diameter would fit in that space, basically removing the option for an original Tesla tyre.
I don't think that a Modern Spare would fit either. Maybe it could be placed tilted and not fully flat?? 2020-2021 Tesla Model Y Spare Tire Kit Options
An option would be to put in a Vredestein Expandable/Collapsable tyre which should fit?
Two options I've found that have the same rolling diameter and space for callipers a
- Vredestein SpaceMaster 185/55-20 100P (rolling diameter 28, same as original tyre) - used in Mercedes Benz S class
- Vredestein SpaceMaster 195/55-20 102P (rolling diameter 28.4 inches, meaning+0,4 compared to original tyre) - used in Porsche Cayenne Turbo
- Vredestein SpaceMaster 185/65-19 104P (rolling diameter 28.5 inches, meaning +0.5 compared to orignal tyre) - used in Mercedes Benz ML AMG
I am no expert on tyre sizes, and there are a bunch of other Vredestein for Audi, VW etc which has a rolling diameter +1.5 or similar.
This is to be compared to Tesla Model Y Induction Tyres 20 inch rim: 255/40-20 XL 101W
So my question to anyone interested in this forum and who owns a Model Y, any possibility you could lift the lining from the back of the car and check the size available in the "box" the undertrunk forms? That would be greatly appreciated!
And last but not least, everyone has their own reasons for a spare. I fully understand why many auto manufacturers have opted to remove the spare. However, I do not agree with the fact that the engineers have taken away the possibility to have a spare for those who actually want or need one. I will always carry a tyre puncture kit, guck on spray. But, I will be driving along roads where there is 50-100 km gaps between towns and where there is absolutely no mobile coverage in between. Even if I carry a Thuraya sat phone for emergencies, it will put me far, far away from nearest truck to rescue me.
So for those who want to share how many years they have driven without a flat, managed to fix the car with guck, or stating the danger of changing a tyre because of driving by traffic... please refrain. This post is not about that.
I've had 6 punctures in 25 years. 5 of those happened on more or less deserted roads. 2 of those happened in the middle of winter at -15 or below without any cars passing by for half a day or more. The only danger was freezing to death as there was no network coverage. A tyre change fixed everthing. Now having relocated to a hotter climate, I don't want to die in 40 degrees weather because someone decided people don't need spares or the option to store them safely. I'm old enought to know how to change tyres.
I would appreciate any help in finding out if this mod works for the Tesla Model Y as I absolutely need a spare.
Cheers!
