Spare tire for Cybertruck?

@Ogre promised to buy a dozen or so for members here. Never forget

I’m liking the 6 tire rotation a lot. It means if one gets damaged or wears unevenly you don’t end up replacing all 4 because they need to be replaced at the same time.

@John K Also I think we’ve only had 1 of 30 % days.

We are all keeping count. Plus, the count does not start until $1000 / stock split

These tires aren't unique to Tesla. And warranty repairs have to be covered and they can't require you to use their techs just because it's a warranty (tho they can for other reasons).

A Tesla has jack points just like any other car, they're required by DOT rules.

But they need special pads that connect into holes at the jacking point. Not supplied oe so have to buy aftermarket. The pads reduce the space for you jack to get under so I have a small 6” x 1 1/2” block to drive onto get get that extra bit of ground clearances

.meh… tire pressure is more important than rotation.
On 5 tire you are running against the bias/steel belt everytime a tire switches side(i.e. direction).
With 6 tire, you are backing 1spare ea. for L and R. Thus keeping roation in bias with the tire breakin.

They no more need 'special pads' than they use lift points (which are standard on industrial lifts and jacks) instead of bars or flat lifts. My Mazda wants a jack with a cleft in the lift point. It's just one of many ways of doing it.

It's just like how some motorcycles require an arm lift vs a table lift.

Teslas have lift points, but they are tiny compared to the unliftable area (in red):

Lifting a Tesla by the pack will undoubtedly damage it, thus the "special pads" are intended to provide a margin of safety for 3rd-party mechanics (giving benefit of the doubt to Tesla service centers).

The structural pack is much more robust. Sandy is still working on his teardown lol

Yes. Which in no way contradicts what I wrote:

Yeah, my jack for my Mazda won't work without an adapter on a Tesla. But the converse is true, a flat bar lift might crush the clip point on my Mazda.

Many modern trucks, like the F150 Lightning, come with a non-conforming/dissimilar full-sized spare (I.e., differently sized wheel and tire from those on the ground).

Mention it here because someone earlier said something like “if Tesla doesn’t offer a spare like other manufactures people will notice” - and pointing out that doing it “like other manufacturers” might mean a non-confirming/dissimilar spare.

which would solve all the tire rotation math problems being presented in this thread (pun intended)

A space for a full sized spare that can be used as storage would satisfy everyone I think. Just the spare becomes an option.

The CT may adjust the pressure automatically, depending on the road condition.

I would expect it as an option.

As far as the spare wheel... rather than wasting space in the bed, I have come to terms of going without. I can't remember the last time I changed a tire.

Worse comes to worse.... theres a fix.

Speaking of spares, my wife just realized the Leaf comes with no spare. We had to go to the car and she looked for the spare I assured her was not there.

If CT has CTIS I'd expect to pay a premium for it, probably in the $2-3k range. It would be a game changer off-road though. A space for the spare is actually more important than the spare, in that it gives you the option to carry one without impeding the use of the bed.

Amateur response .. Brace yourself lol

CT already has an air compressor, rather than run tubes to each wheel from there, I reckon channels could be built into the battery pack .

The wheel assembly with all this wiz bang tech, including CTIS, is connected to the body.

Price should be a fraction compared to an aftermarket add-on.

If anything it would be just tubes going to the wheel knuckles and pressurised bearings to the wheel hub that spins with the wheel, like the Unimog CTIS on portal hubs..

The biggest problem is finding a pathway for the air pressure from the truck to the spinning tyre.

Portal hubs make it possible, and seeing we will likely only get quad motors might even be a possibility now. Better ground clearance, smaller driveshafts, and you can put the brake discs inboard too to save unsprung mass.

We just haven't seen any CTs with it yet though.
