CYBERTRUCK TIRE EATS A BOLT IN A REMOTE LOCATION ON SUNDAY MORNING

[HaulingAss]

Yeah 1 Gallon isn't going to do a lot but it helps keep down on continuous runtime (ARB offers a 4L tank for their twin compressor which does indeed help). But it can be there as an add-on for using it for other items out of the truck, like nail guns, etc. The key for me is not waiting 25 minutes to fill a tire and burning it out. A lot of those tankless air compressors have a 10-15 minute run time before you have to shut it off for a while. I would like to at least get 1 tire off of it without worrying the compressor will crap out. The small tanks seem to have a more runtime. Some tankless ones can have long runtimes, but then you are looking at $600+ (like my ARB Twin Air compressor in my Jeep). Since this is a rare event, I just want something that is reliable and will work without breaking the bank.

For the bead, just need some starter spray and a lighter ;-)

A tank does not decrease runtimes, it increases them. Because the tank has to be inflated higher than the tire pressure. And when the tank is empty, it has to be re-pressurized. This is a common error in logic, that the tank helps reduce runtimes. It increases runtimes.

All manufacturers of portable compressors recommend transporting them unpressurized and draining the pressure daily. That's just more volume to pump up if you follow their recommendations.

If you don't believe in following their recommendations, and you hook up the compressor you linked above to a MorrFlate system, and the tank was already pressurized to start, it might reduce runtime by 30 seconds to a minute. And you would still need to re-pressurize the tank (if that's how you are using it) or else the next time you use it it would require longer runtimes to fill the tank first. The tank adds no benefit in this application, it is a net negative in multiple ways.

I believe in rigorous thinking, not fuzzy thinking to justify what one wants to believe.

I always purchase the tire warranty from Discount Tire for situations like this. For less than $300 all your tires are covered for repair and/or replacement. It’s come in handy on my previous TESLA’s.

Do you know if discount tire can get the actual Cybertruck AT tire?

Yes, I went to Discount Tire and they said they are able to get the exact AT tire. Salesman mentioned its “the same tire they use on the Humvee”. Not sure if that is a true statement.

That is absolutely not true. The tank gives the duty cycle a break. Read here:

I own multiple air compressors of differing sizes for years. The bigger the tank, the shorter the duty cycle. Having a 1 gallon will give the compressor a break... albeit not a huge amount, but better than tankless. But a tank certainly doesn't increase the duty cycle... thats exactly the opposite.

What? Who is fuzzy thinking? WTF dude? I gave you a compliment to your compressor as it looked cool. I also mention a tank version for duty cycle. What is fuzzy thinking here? A tank reduces duty cycle. Period. Of course you would unpressurize it when you are done and drain it. It's a 1 minute process on a 1 gallon. That is air compressor 101.

Another arguer just for the sake of arguing... love it!

Interesting…. I have a hard time believing that since the cybertruck AT tire has the cut outs that line up with the aero wheel cover.

I think Tesla is done with those Aero covers. They are popping off when tire pressure is lowered for off roading. The tire bulges out when pressure is lowered and pushed the covers off. Interested to see the fix. Another problem with the aero covers were no holes for the air valves.

I'm absolutely not arguing for the sake of arguing. You need to chill out and stop being so cocky and you might actually learn something new instead of swinging your dick around. Then you have the nerve to link to very basic explanation of compressor duty cycles written for a complete novice?

I'm a generous person and will try to explain it to you in a manner you will understand. This isn't about being right, it's about knowledge. It's about the way the process of filling tires actually works.

Let's start with the compressor you linked, and that 1 gallon tank charged to 90 psi, hooked up to a system like the MorrFlate system that will fill all four tires simultaneously. Almost as soon as you open the valve (about 5 seconds) the compressor will cycle on. It will remain on until all four tires reach pressure and you close the valve to the tires. Yes, it will fill your tires back up anywhere from around 10 to 20 seconds faster than if you had no pressurized tank in-line, but now your tank is essentially at tire pressure. That means the compressor will keep running until the tank is back up to the cutoff pressure (90 psi in this example) and it will take a bit longer for that to occur than the 10-20 seconds initially saved. There is no free lunch.

Alternatively, you turn off the compressor and put it away with only the 50 psi in the tank that you filled your tires to. Now, next time you go to fill your tires up, as soon as you turn on the compressor, it will start pumping the tank from 50-90 psi. You have gained nothing, just lost some efficiency.

The runtime will actually be slightly longer, and your compressor will be slightly hotter, all because the average pressure it was pushing against was higher than the instantaneous tire pressure at any given time that a compressor without a tank would have seen. Compressors lose efficiency and work harder as pressures rise.

The reason the primer on compressor tanks you linked to is not applicable here at all is because the speed of the compressor is too slow to keep up with the air flow into the tire inflation hose. The compressor will run continuously until the tires are full. It will not overheat because it should only take about three to 5 minutes maximum to inflate them.

The compressor I have, linked to above by another participant, fills all tires in one duty cycle of 4 minutes. A tank would be a net negative in terms of wear on the compressor and energy used. It is more efficient to use your tires as the tank and only have the compressor work hard enough to reach the final tire pressure. The MorrFlate system, and all others like it, is essentially a full flow system, it's different from using a pneumatic nail gun or impact wrench on a periodic basis. Two different use cases. The tires act like an air tank. Adding a small one to that, one that runs at a higher pressure, just reduces the overall efficiency.

Hopefully, you are able to put aside your ego and learn something here. I am not new to the principles and physics involved.

LOL.... if that ain't the pot calling the kettle black! Your posts are arrogant and untrue. I'm not the one doing the BSD... you are. I'm stating facts. Yeah...I get pissed when you and 2 other members (who shall be nameless) start blowing BS with no factual back up, spouting things that are not true. I at least point to facts.

Its funny. Every link I post is not good enough for you. You always have a response. You didn't get the post. It's not runtime I am concerned with overall. It's *duty cycle*. Typically the cheaper the air compressor, the lower the duty cycle. As I stated before, the expensive ARBs (i.e. the twin air compressor) can have nearly 100% duty cycle times. Sure, I can buy that and be done with it. but for something I am going to use a handful of times, its a ridiculous amount to spend.

I linked to a Makita. I simply stated that I was *also* looking at a tank version mostly for duty cycle. All you had to say was, the one I have (still awaiting your link for what it is and where you got it) has a 100% duty cycle and can do all your tires in 1 shot. BOOM! Over. Perfect product for me. Thanks @HaulingAss... thats a great product and I will order one!

Instead you go into some diatribe about how duty cycle is longer with a tank which is 100% untrue. Ever wonder why ARB sells a 4L (1 gallon) tank as an add on to its twin air compressor? I'll let you Google that one yourself. I'll also let you Google the number of sites out there who have duty cycle calculator based on CFM and tank size. There are a lot. The main takeaway: Duty cycle is inversely proportional to tank size.

Hopefully, you are able to put aside your ego and learn something here. I am not new to the principles and physics involved.

My ego? Seriously? Wow.

how do i even buy a spare tire ? ive been lookin allday if anyone has any tips please lmk ty

The Tesla spare (https://shop.tesla.com/product/cybertruck-spare-tire-_-tool-kit) is out of stock right now, but was available not long ago.

Third party options, like Modern Spare (modernspare.com) should be available shortly.

Before I even got my truck, I bought this well-reviewed patch kit:

https://a.co/d/632eXwU

I've already used it, but not on the Cybertruck hahahaha. It plugged a nail puncture well, didn't even need to jack it or remove the tire.

I also have a battery-powered compressor, but based on my tests, I would need to recharge it at least once to fill a completely flat tire lol

This patch kit is solid! I bought it 8 years ago and just used it again for my niece's car couple of months ago. It's working great even though it's been sitting in my hot car all these years.

 

[future_yas]

This is why all other trucks come with a spare tire but Tesla expects you to pay $1300 for a spare tire kit and keep it in your bed taking up useful space.

Rivian doesn't come with a spare. It costs extra. You should compare the prices and get back to us so you can show us how overpriced Tesla must be.

Most buyers don't want a spare, maybe because they know plugging a puncture is easier and faster, and doesn't involve jacking the vehicle.

The main takeaway: Duty cycle is inversely proportional to tank size.

Overal duty cycle is output CFM/ compressor CFM. A tank doesn't change this, but does increase the on and off durations. If the outflow is higher than the compressor output, it will run continously since it never gets to the high limit cutoff. For a low CFM compressor filling four tires, this may be the situation.

The tank only speeds things up if it starts well above tire pressure and finishes at tire pressure. Otherwise, it is just more volume to pressurize. If you leave the compressor running after shutting off the tire inflation, that run time filling the tank will speed things up the next time.

Used to be...

Used to be wheels and trucks were smaller, consequently lighter; and more likely to fail, too.

There's just no reason to carry more than a patch kit most of the time. I'd druther have that volume and weight saved.

And if you do go out where it'll be needed, well, that's when you put it on the truck.

This is why all other trucks come with a spare tire but Tesla expects you to pay $1300 for a spare tire kit and keep it in your bed taking up useful space.

And dude, it's always taking useful space, it's just wasted on older trucks. The Cybertruck uses that space for useful storage and a shorter truck length.
