I show why is it important to not only fill your tires up to the correct pressure but also use the CORRECT AIR! Learn how to replace winter air, with summer air!
Most people know when filling your car or truck tries that you need to fill it to the correct air pressure. What people dont know, is the air that goes into the tires is just as important. Winter air is cold, dry, and dense, therefore heavy while summer air is warm, humid, and light. Running winter air in the summer will cause lower tire pressure and decreased fuel economy (mpg). Running summer tire in the winter, will cause loss of traction and over inflated tires which could lead to a blow out!

Hey guys, chrisfix here and today, i'm gon na show you how to remove the winter air from your car or truck tires and add in summer air. I'm also going to show you the importance on why you need to do this now. Most people understand the importance of properly inflating your tires. This is something that you learn when you first learn how to drive, but what a lot of people don't pay attention to is the actual air that you're putting into your tires, which is just as important, for example, we know that over inflating your tires bed, it Could cause a blowout? It could cause the middle of the tire to wear, and we also know that under inflating the tire isn't good as well.

It'll cause the sidewall to be spongy. You're handling won't be good and it'll cause the outside of your tire to wear. Also you'll get very bad fuel economy. If you ever tried pushing a car that doesn't run.

Usually it has flat tires and you'll know how difficult that is to push. But if you inflate the tires to the proper pressure, you know you have a better chance at moving that car, because it's easier to push so properly inflating your tires is pretty common knowledge. Most people get it, but what a lot of people don't think about is the air that's going into your tires when you fill it up. If you fill your tires up in the winter, you're adding cold dry heavy winter air, this is completely different than adding air in the summer, which is warmer humid and lighter, so because of the big difference between winter air and summer air.

When the seasons change like right now we're going from a really cold winter to hopefully a nice summer, you want to change out the air in all four of your tires for all of your vehicles. Now don't just take this from me. I spoke with an engineer with many years of experience and he's made countless videos about the science of tires. So he knows what he's talking about thanks Chris, you know I'm always down to talk about tires.

I'm Jason with engineering, explained an engineer with over 75 years. Experience, you can see it in my hair and Chris is definitely right. You don't want to run winter air in the summer or vice versa. It all comes down to the ideal gas law, PV equals n R T.

Now I don't want to bore you with all the crazy math, so let's just make this simple, the ideal gas law only works for ideal gases, and only summer air is an ideal gas. Winter is not. You can tell this by looking at the different molecular structures. Now the biggest difference with winter air not being an ideal gas, is that it weighs more.

So if you were to take a tire and inflate it to the same pressure with winter, air and summer air, it's going to weigh more with winter air in it. Now that extra weight is great for digging into the snow and providing traction and slick conditions, but it's terrible in the summer when you're trying to drive fast and have fun when the sun's out you want lighter air. In your tires back to you, Chris thanks a lot Jason all right. So not only do you know the importance of running the correct air pressure, but now you also know the importance of running the correct air in your tires, since we're going from the winter to the summer.

We want to run summer air. So now I'm going to show you how to flush out all that old winter air and fill up with some nice fresh summer air. Now I do want to mention, if you're getting your vehicle serviced soon, maybe you're gon na get an oil change or a tire rotation. Just ask the mechanic who's working on your vehicle to switch out the air from winter air to summer air, usually they'll.

Do it for free takes them a couple of seconds? They do it as a courtesy, but you have to make sure that you ask them. If you don't ask them, they won't know to do it, but let's just say you want to do it yourself. I like working on my own cars. I like getting everything done myself.

Let's say you're the same way and you want to do it at home. Well, guess what it's really easy! You don't even have to jack up the car. We can leave it right on the ground and here's all the tools and products you're gon na need before you begin working on your car. I always wear some gloves and since we're working with pressurized air put on some safety glasses, now we could get started and remove the air from the tire so remove the dust cap from the tire valve stem and with that removed, put it someplace that you're not Going to lose it now to remove the air from the tire you have a couple of options.

First, you could get yourself something like a key or flat-head screwdriver and depress the little valve in here and let the air out, but this could take a long time. So instead I like to remove the actual valve from the valve stem, and to do that, you have a couple of options. Most people have a needlenose pliers like this. You could just go right in here and loosen it up.

Just like that, you could hear that air coming out already. The other option is to use a valve stem core tool like this, and this just goes in and you unscrew it same way: you're using that needlenose pliers and once the valves unscrewed all the way, the air pressure will push it out for you. What's actually pretty cool is you could feel that cold winter air being let out of the tire and this process will take about a minute to fully flush all the cold winter air out? So, with our tire completely flat, all the winter air has been let out now we can reinstall the tire core back into the valve stem and a little tip before we install the valve stem. It's always a good idea to lubricate it with some elbow grease.

This will help it seal better and keep the moisture out and when you're tightening down the valve stem just make sure it goes in smoothly. There shouldn't really be any resistance. You don't want to cross thread it and don't over. Tighten it just get it tight.

So it's snug just like that perfect. So, with our valve core installed and all the cold winter air removed from our tire now, we could go and refill the tire with summer air. So we have two options. If you have a compressor at home, you could use that just make sure your compressor doesn't have that cold winter air in here already in this case, I do if you need to purge it.

You just pull this valve right here and you can purge all that old air out. I don't feel like running this. It's loud and obnoxious. Also, not everybody has a compressor, so I'm going to show you how to do it at home with cans of summer air you're gon na need one can per tire.

So I have four cans right here and you could easily find these at your local parts store. So you can walk into just about any car parts store. You want to find the aisle that has the tire repair kits right over here and, as you can see, we have our summer and winter air. Now, if you can't find this go, ask one of the people behind the counter, I'm sure they'll help you out.

Luckily, I bought these back in the fall when they were on sale when everybody's looking for that winter air. So I have four ready for my truck now. What tire pressure should you fill your tires to? Well, you just look inside the door, jamb and right here on the door jamb sticker. You can see right there.

It says 30 psi cold for both front and back tires. So that gives you the correct pressure, and now all you have to do is fill up the tires. So, let's get our summer air and thread on the hose to the tire valve stem now just hold down the nozzle at the top of the can that's gon na take about a minute or so to fill a large truck tire with summer air. If you've ever done this before, you know the lighter summer, air pumps, the tire up a lot faster than if you do it with the heavier winter air.

Alright, now it is that simple to fill your tire up with the correct air. We have a hundred percent summer air installed in that tire, and it's ready to go for this summer season. I can't wait. It really.

Is that easy to do and again, this is a very good thing to do check this out now to show you guys the difference between winter air and summer air on the del Sol that I'm working on rebuilding the entire front suspension. I got brand new wheels and tires now these tires were mounted in the winter, so all these tires have winter air in them. So, let's put one on the scale to see how much it weighs with the winter air looks like 40 pounds, 12 ounces, now to remove all that winter air out of the tire and let's fill it up with the lightweight summer, air. Okay, let's see what the wheel weighs now with the summer: air 34 pounds 12 ounces and, as they say, the proof is in the pudding.

This was a great example of how much weight savings you have when you're using summer air over winter air, six pounds per tire - that's 24 pounds of rotational mass. That is saved. That is a huge number and that's why you see race, car drivers filling up with fresh summer air before every race. And finally, there are two situations where you don't have to change the air.

In your tires, you always want to check your tire pressure, but you don't have to change the air if you live in an area where the climate is the same in the summer and in the winter, if the temperature doesn't change, you don't have to change the Air in your tires - and the second reason is, if you have a green valve cap like this on the tires that means your tires - are filled up with nitrogen air. Nitrogen doesn't change pressure with temperature or changes very very little, so you don't have to replace your air in your tires if you have nitrogen. So if you live in a climate, that's similar all year round or if you have nitrogen your tires, you don't have to replace the air in your tires and one last thing that I need to mention, because if I don't, I know, there's going to be tons Of comments about it, if you off-road your truck or you tow with it, it's better to run a winter air, even in the summer, the cooler denser heavier air holds those tires to the ground. Better, you get better traction and when you're towing it keeps them cooler.

So what I do I run summer air because I mostly ride on the road, but I do carry a can or two of winter air just in case, if I get stuck so it's very helpful in that type of situation, so there we go. That is how you change out the winter air to the summer air. In your tires, it's that easy to do and it's that important to do.

    Can you make a tutorial for how to patch a wiring harness and refill it with smoke, please?

    The shop is trying to sell me a whole new harness. Nice try, I took it back home and I think I found where the smoke leaked out from.

    I'm not sure what I'm doing wrong.

    I wrapped the wire with tape and found the smoke reservoir on the battery. It was full of water(!) for some reason. I guess that means the seals are bad?

    I dumped the water out and put some fresh smoke in, but still no luck. Maybe it got air/water in the wires?

    Is there a purging procedure to decontaminate the lines? Or maybe I'm using the wrong smoke? I couldn't find any smoke kits at the parts store, so I used the beekeeper stuff. It's all natural, which I thought would do the trick, but maybe my car needs synthetic?

  2. Avataaar/Circle Created with python_avatars Dalton Burgess says:

    I was legit so confused cuz I know this was bull crap but just him having the cans of the air and going into a the parts so had me second guessing everything in life lmao

  3. Avataaar/Circle Created with python_avatars Rotor Blade says:

    You can use a silica filter for the compressor intake to fill the tires with dry air which is better and an alternative to nitrogen fill
    The filter can be made very easily:

    You need a tube to connect to the compressor air filter
    Next you need a bottle for silica, at least 1 litre.
    Make a whole in the bottle cap to insert the tube
    Make holes on the side of the bottle
    Buy silicat (used for cats) which is easily available and fill the bottle.
    I use such a filter for a high pressure air pump and works well. The original used like 50ml of silica and was worthless, too small

    where can i buys some…. but for real my question is … what is the correct tire pressure for my vehicles tires? i see talks of people say fill to what is on the inside of the door. some people say to what is on the tire sidewall. i want to know what is it???

  5. Avataaar/Circle Created with python_avatars poiisondn says:

    ChrisFix could convince me that his magical blue gloves will fix my car and be able to sell me those gloves at a huge markup. I'd take it.

  6. Avataaar/Circle Created with python_avatars atlys says:

    Living in Phoenix, Az is nice because we can easily drive with summer air all year long 👍👍

    I know it's a joke, but "nitrogen air" had me dead 🤣🤣

  7. Avataaar/Circle Created with python_avatars Aurelio Gracia says:

    Still pretty logical…. Like a woman getting pregnant in summer so the baby will be born with a darker skin color vs a baby born in winter with a lighter skin color……..logic…………

  8. Avataaar/Circle Created with python_avatars Indy HotDog says:

    I am a PhD chemist. This video isn't necessary. Just check your air pressure monthly (or after large, seasonal changes). I think Chris is a cool dude, but if you simply do what experts recommend, you'll be fine.

  9. Avataaar/Circle Created with python_avatars Aaron Michael Bell says:

    Oh my god I actually come from a region where everyone has 2 sets of wheels summer and winter, and I was wondering what the heck… Halfway through the video I was like “Ok as we swap the whole wheels so there is no point changing the air…” Man you got me with this one 😂

  10. Avataaar/Circle Created with python_avatars JMUDoc says:

    It's a good job these are all harmless – Chris is so damned convincing that he could have some people pouring Rice Krispies into their oil filler caps, if he wanted to…

  11. Avataaar/Circle Created with python_avatars Dayson Boon says:

    Im watching this on July 28th 2021 and I was like wait a second, this is another April fools video isn't it. And then I checked

  12. Avataaar/Circle Created with python_avatars K H says:

    Don't like how you did not check the psi on the tire it self, also before comparing weight. Thanks though. Great videos 👍 !

  13. Avataaar/Circle Created with python_avatars Yellow Jacket says:

    If the people who sold nitrogen inflation services would do this pitch they would have put people on appointments to keep up.

  14. Avataaar/Circle Created with python_avatars Stefan Schuh says:

    Should have changed the plate inside the door, to say cold air pressure, and hot air pressure. Need hot air for summer, since it's lighter (wink) I get much better gas mileage with hot summer air in mine

  15. Avataaar/Circle Created with python_avatars Hiterra says:

    Hey, I have a really important question.

    My Fiesta's tires seem to change shape a week later after I put summer air in it, could it be that it requires autumn/spring air for periods in between? And if yes, where can I get it?
    Btw, another quick question. What's does the 710 mean on a screw on cap in my engine bay? Is it some type of oil/fluid/liquid? And should I change it? Because I haven't put anything in it for 6 years now and my engine is making weird knocking sounds for a year now (Probably piston return springs, need to change those out too)

  16. Avataaar/Circle Created with python_avatars Noskiz says:

    I remember when I watched this in 7th grade and I recently remembered this video and thought omg I really thought it was real back then wow lol

  17. Avataaar/Circle Created with python_avatars Daivd Yin says:

    I am here because I was fooled by the piston return spring hoax, so now I am watch all his April fools video!!!
    Nice cameo by Engineering Explained, you almost had me doubt my Thermos lecture. Winter air is not ideal gas, LOL
