R1S Compact Spare Tire - First Look

[Madsen203]

I guess that's the beauty of 4 independent motors. Wonder how the quickly the truck figures out which corner you put the retarded tire on, or will there be a setting for that in the R1S?

Edit: wonder what happens when the dual motor trucks arrive and you have one motor driving the whole axle?

Even more interesting is the possibility of air suspension accommodating for the lower ride height.

Haha, if I lift the truck to max height with the ATs, will that tire be dangling??

Interesting question. Some AWD systems have a lot of trouble with smaller differences in diameter than this. Their logic might be more forgiving though.

Obviously, for those of us committed to an R1S the current choice is this donut spare or no spare. I’m getting the donut. If Rivian offered an optional swing-out mount full size spare from the factory for the R1S I would seriously consider it despite the added complication every time I needed to access the cargo area.

It was a dumpster fire because the beads wouldn't seat and take pressure because of how it was folded in on itself.

I don't have any experience with this kind of spare. How often do people actually run into this kind of problem? And what about problems deflating and having it fold back up properly?

Pros/cons of this vs a can of fix-a-flat? Is this compact spare speed limited to 50 mph?

edit: the last 2 flats I've had around town couldn't have been mitigated by fix-a-flat but the conventional spare has always been a reliable alternative (ie, no bead seating issues, etc). guess I'm wondering just how reliable this inflatable compact spare is. perhaps I'll just have to get the spare and carry a can of fix-a-flat.

I wish Rivian would let you purchase a full-size matching spare for the R1S from the factory, even if it won’t fit in the well. I know you can buy them through service, but my understanding is that’s more expensive.

Only one way to find out

interesting. I don't know if I'd rather just have the cargo room, and then get something like this and a full size spare when I'm adventuring further than my local grocery store:

I can only speak to my experience, but fix-a-flat would but have fixed mine. The sidewall got borked. Only needed my spare once and it failed me.

It deflated perfectly, though.

Nice find, thanks for sharing.

I had to look up how it would compare visually, and stumbled on https://tiresize.com/comparison/

Compared to 20" All-Terrain

Compared to 21" All-Season

Compared to 22" Sport

How the hell does that even work if it's not remotely close in size to any of the offered wheel/tire combos!? I guess maybe it's confirmation that having 4-independent motors you can run a different size without the computers freaking out and doing weird things with the ABS/stability/traction control.

That's the route I'm planning to go but maybe a simpler one like this that can still have an accessory like a bike rack behind it:

I've been lucky that all the flats I've had in the last few years have been quickly fixed with a tire plug, even when I've had a full size spare available. It's just been easier to put a plug in and air back up instead of changing the tire.

 

[dleepnw]

Yes, it is not.

huh?

 

[Friscorays]

so its an inflatable tire. does anyone know if the wheel/rim the same as the other 4 wheels?

Yes I know: no, it is not.

By the looks of it, it appears you may not be able to access the rear of the R1S with that etrailer mount. That 34” tire will likely not allow for the lowering of the tailgate. I would also be concerned about how stable it is in a rough, offroad situation. Unfortunately, by the time one gets a spare tire and mounting system there’s another $2500 +/- out the window

Spare tire on the back is nothing a little engineering and welding can't fix!
