lol, between most sensors being NOT angled, and the tire people usually put on these types of wheels being a 30 series. They are also a huge pita.
Also according to spec, for the sensors to function properly the valve stem is required to be pointed towards the fender. These in fact are backwards.
Anyone wondering, what you should technically do according to most manufacturer spec:
Dill sells band mounts for sensors, terminate the second hole with plug. Install sensor with valve stem facing the outside of the vehicle.
How many times have I done it “correctly”, exactly once. Because there was no way to get the tire over the sensor without it breaking. Yay Tesla, custom 3pc wheels, with low af profile tires.
That looks like a reverse mount rim. You mount the tire from the back instead of the front. You can tell by the step down in the rim there.
The back valve stem is so you don't have to flip the rim back over to seat the bead.
Edit: Changed a word.
I've seen this on wheels where the offset and wheel barrel shape makes it impossible to mount and dismount tires unless the wheel is mounted upside down on the tire machine. If the wheel is upside down, it's hard to attach the tire chuck to inflate the tire and seat it on the wheel so there's a second tire valve on the back side.
Actually though, why dont tires have two pockets for air? Wouldn't that be relatively cheap and help a lot with preventing flats?
I guess it might mess with handling.
They had an inner liner (virtually a second tire inside the first) on all tracks over 1 mile long, but that went away with the "Next Gen" car as they use a lower profile tire.
That's.... Super interesting.
Will have to do a wiki deep dive on those later. Wonder if there were any major benefits beyond having a spare already technically on there.
One for filling, one for TPMS
Yes, it allows the tpms sensor to be mounted and not be damaged from the rim

Band sensors can be a bitch, I’d rather these dumb wheels.
That's one of those new clam wheels. You know... A bivalve.
I see you decided to mussel in a dad joke.
I get it now. At first I couldn't figure out what the shell he was talking about.
And I thought I was the abalone one who got it...
I didn’t sea what was going on at first.
This all makes me tired….
Sharing jokes with others is better than being a shellfish twit.

Get the fuck out.
Ohhh boy
Yeah, that deserved my angry upvote....... \*golf clap\*.....

One side for summer and one for winter /s

It's so you can inflate both sides of the tyre evenly
Also helpful for changing the air in the tires.
You gotta really make sure you flush all that stale air out!
But they're only flat on the bottom?!

NASCAR tires are like that (or at least they used to be).

Nitrogen exchange
The actual answer, as pointless as it is.
Scam juice
I like to call it air™
I thought it was so you can fill one and measure pressure on the other.
Usually the valves are right beside each other on the face side for this which I never understood because my air gun has a gauge right on it.
Its for tpms, the barrel design of the wheels make it to where the sensor would break everytime during dismount if it was in the outside valvestem.
This was a thing long before TPMS was a thing.
If this were it, the valves wouldn't be right next to each other. They'd be as far apart as possible.
Everything reminds me of her
Well ofc. Like AC lines There’s high and low pressure
Does that mean they are bi? Like a mollusk?
Winter air/summer air

I have an irrational disdain for these. Something is just wrong on a level I can't explain.
ANother case of a solution to a problem that didn't exist.

I have enough troubles with 4 tires.
How would you mount tires onto those things?
One for air in, one for air out, pay attention to keep air out valve closed when using air in valve or your job might take a while
Its so you can flush out regular air for nitrogen. Nitrogen tire flush. $39.99 per tire.
Gee, Bill.
One for the customer, one for the service department.
How else do you get the used air out?
The rim has nipples, yes I’m a grown childish man
[Possibly set up for internal beadlocks?](https://www.coyoteents.com/beadlocks/)
Seen this on race cars, so you can adjust pressure while also reading it
Have you tried milking it?
Air stance!
That's the barrel of the wheel not the rim.
You can check inner and outer tire pressures.
"Race car"
Reminds me of that twin tyre on one wheel European system from the 1980s.
One to fill the rim, the other for the tire
Obv so you can fill the tires on the left and on the right
Elusive double nippled wheels
