How to Check the Tire Pressure for Traction, Handling & Comfort


[HOW TO CHECK TIRE PRESSURE FOR TRACTION, HANDLING & COMFORT] Hi there smart drivers, Rick with Smart Drive Test talking to you today about tire pressure. Tire pressure is important, especially in the wintertime because you get drastic changes in temperature and those drastic changes in temperature can negatively affect the tires’ pressure. Tire pressure is important for handling of the vehicle, especially when you have winter tires on, it will maximize your grip and keep you on the road as you’re going around corners. So it’s important to make sure that you have the correct tire pressure. Every vehicle, every driver should have one of these in their vehicle – it’s a tire pressure gauge. Pick one of these up for less than $25. Not only will it maximize the handling of your vehicle for optimum performance, but as well, it will increase your fuel mileage, and it will increase the life of your tires. So today we’re going to talk to you about tire pressure. We’ll be right back with that information – stick around. [OPENING CREDITS & MUSIC] Hi there smart drivers, welcome back. Rick with Smart Drive Test, talking to you today about tire pressure. It is important to have the correct tire pressure because it affects handling of your vehicle, particularly in the winter time when there are drastic temperature changes. It will affect the tire pressure inside your tires. If you’re tire pressure is too low, it’s going to increase fuel consumption and as well it’s going to reduce the life of your tires and cost you money. The other thing that low tire pressure or too high tire pressure is going to do – it’s going to affect the handling of the vehicle. In the wintertime, this can be dangerous because it could potentially put you in the ditch – worse yet, you could have a crash. So correct tire pressure – you should check the tire pressure at least once a month or anytime there is a drastic temperature changes. And every vehicle should have a tire pressure gauge in it. You can pick up a tire pressure gauge at your local auto parts shop or maybe some of the hardware stores will carry these. And a tire pressure gauge sells for about $25 – actually for $25 you can get a pretty good tire gauge. So have a tire gauge, check the tire pressure and always check the tire pressure when the tires are cold. In other words, don’t drive the vehicle and then check the tire pressure because you’ll get an incorrect reading. So always check the tires when the tires are cold and you haven’t driven the vehicle. So where do you find the correct tire pressure for your vehicle? The first place and the most easily found place is on the door sill of the driver’s side. You can find the tire pressure there on the little sticker that’s down beside the driver’s seat. The next place you can find the tire pressure and how to inflate the tires for your vehicle or the tire size is the owner’s manual. And the owner’s manual comes in book form, comes in electronic form, or if you have a newer vehicle it’ll be telematics, and you can find it on the menu on the screen on the dash. The owner’s manual– I know–is less read than my PhD dissertation! But there’s a lot of really great information in an owner’s manual about your vehicle. So have a look in the owner’s manual for the correct tire pressure. Now on this vehicle here, it’s 26 pounds per square inch. In North America we measure in pounds per square inch. The metric unit for pressure is kilopascals. We don’t use kilopascals because it gives you really odd number, so we still tend to use pounds per square inch. So on this vehicle it is 26 pounds is the recommended tire pressure. However every time I’ve gotten this vehicle back from the tire shop, they’ve put in 32 pounds in it. And when I was a kid working in the garage with my Dad, we always put 32 pounds in the tires. And I tend to like 32 pounds – I find it handles a little bit better, so I run 32 pounds and as well I get a bit better fuel economy. So talk to your local tire shop, talk to a mechanic about that if you want to run a little bit more air pressure in your tires. As well the other point about tire pressure is: it’s according to the vehicle manufacturer, not the tire manufacturer. So you won’t find it on the side of the tire and that maybe a question on your license test. One other point about tire pressure, if you’re running a lot of weight on your vehicle or you’re pulling a trailer or something like that, you might also want to compensate your tire pressure. Again consult a technician about that information. The other thing about tire pressure on vehicle – if you have green valve stem caps on your tires it means the tire shop has put nitrogen in your tires. Nitrogen has a couple of benefits. First it has less water content than regular air and because it has less water content the air pressure inside your tires is going to fluctuate less with temperature change. So that’s your first benefit. The next benefit about nitrogen is the process of osmosis, where gas moves through a membrane, i.e. the tire in this case. There is going to be less movement of gas through the membrane. So therefore, over a long period of time you’re going to maintain a more constant tire pressure with nitrogen inside your tires. Now you can put regular air in your tires if you have nitrogen and it’s not going to negate any of the benefits. So you can put regular air. And where you get regular air, if you find out your tire pressures low, go to a gas station– they’ll charge you a dollar–or you can take it to a tire shop and they will check your tire pressure as well. So quick review – tire pressure: check it at least once a month or anytime you have drastic temperature changes. Pick up a tire pressure gauge – you can check the tire pressure quickly – less than a couple of minutes for the whole vehicle. And make sure that you have constant tire pressure. This good inflation will increase your fuel economy, it will extend the life of your tires, and give you good handling, especially in the wintertime it is particularly important for handling, so you stay safe.

  1. You still need to look at the sidewall for the pressure as well, especially on truck that have had tires replaced. Just checking the owner's manual or door tag could cause you to overinflate your tires which can also be dangerous.

  2. am happy to see you guys talking about tire pressure inform people about safety of tires…. from Benjamin kaltire Zambia

  3. I live in Tn and it's gotten really cold. It was 32* this morning and my psi was down to 20. It should have been 32psi so i had to add air before i left the house. I bought a tire inflator which comes in handy and saves money. I live in a small town and it's hard to find a gas station with a pump that works and at $1.50 for air adds up and there pump always cuts off before I'm done filling my tires so i had to pay more. This air pump that i bought has already paid for its self. Plus it's so convenient.

  4. Hi I noticed a 6-8psi difference this winter between my pressure when measured on a long car trip and the cold pressure. Should I be concerned about it overinflating when on long trips?

  5. Whenever you start driving in a cold place like north side heading to the warm place like south of California the air pressure was rapidly increasing that's the time check and reduce the tire pressure.

  6. HI, My car tire pressure went low on RH Rear tire, I went to mechanic shop and they inflated it. Withing 2 weeks again it went low on same tire. This happened both time in morning when i ignited the engine, not sure what is the problem. Any suggestions..Thanks

  7. I'm from Belgium and recently purchased four winter tires. Like you said I've purchased myself Tire gauge to see how much PSI air and found that my front tires were 34.5 PSI (FWD – Ford Focus Mk1 2003) and rear tires were 32 PSI. I've checked them cold like you said so I think when they installed they done that on purpose ? Is it normal to have more PSI on front than rear ? Should I equal all of them ? If so what PSI ? My tires are 215/40/17R

  8. My door jamb says to inflate the tires to 36 psi. And I hear in winter they say add 3 psi to that value. 39 psi seems awfully high of a pressure for winter no?

  9. My tires are reading 25-27psi the recommended psi is 33psi. The tires seem pretty solid; i'm actually afraid to put more in. Could I put more air in without fear of the tire bursting on me?

  10. Hi mate I’m from Australia and recently doing long distance drive, I was advised for long highway trips to little over inflate my tyres my Audi A1 normally sits on 32-34 psi so currently have them on 38psi is this true?

  11. my question is when a tire is low on pressure when the tires are cold how much air should ou put in them when they are warmed up? My tires according to the sticker is 35 psi( I take it thats when its cold)

  12. why do some shops put more air in 1 tire. i bought tires for a truck and the rear passenger tire wore out faster then the others, I checked the air and it had 40 lbs and the others had around 35lbs
