When should I check the inflation of my tires?

When should I check the inflation of my tires?
Experienced mechanics share their insights in answering this question :
There are few things as important to both safe driving and saving money as making sure your tires are properly inflated. Low tire pressure creates excess wear and results in higher fuel costs. High tire pressure creates unnecessary wear, but also makes your tires more susceptible to damage from debris in the road. Here’s what you need to know about checking your tire pressure.

Use the recommended tire pressure found on your driver side door placard, never the PSI rating on the tire’s sidewall.
Check your tire pressure visually every time you drive.
If a tire looks lower than the rest, check the pressure with a gauge and add air if necessary.
Check the tire pressure physically (with an accurate gauge) at least once per month and before any trip.
Make sure to check the pressure when the tires are cold (before you drive anywhere).

Tip

Keep a tire gauge in the vehicle with you at all times.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

Edmunds states you should check the pressure when the tires are cold, as the friction from driving causes them to heat up and affects the pressure. Check them first thing in the morning or, if you`re already driven the car, Consumer Reports recommends waiting at least three hours for the tires to cool down.
Ford Escape Tyre Pressure

This tyre placard recommends a minimum tyre pressure of 35psi for the 2021 Ford Escape. This is equal to 240kPa and 2.4bar.

The Escape has a tire pressure monitoring system (TPMS) as an added safety feature. This will light up a correlating icon when one or more of your tires is under-inflated.
Check for your tires` recommended pressure on the driver`s side door jamb or in your vehicle owner`s manual. Also, be sure to check your tire pressure before you hit the road as your tires may read as having a higher psi after a long drive.
Tire pressure between 32 to 35 PSI is most suitable for most vehicles. However, one can go as low as 20 PSI (although that is not recommended). Anything below 20 PSI is considered a flat tire.
The most common reasons a Ford Escape tire pressure warning light stays on are a leaking tire, a wheel that no longer holds air, or a faulty tire pressure monitoring system.
Most passenger cars have a recommended PSI between 31 and 35 when the tyres are cold. But with so many different types of vehicles and tyre options you should always refer to your vehicle handbook for the required tyre pressure.
For many passenger cars, the recommended air pressure is 32 psi to 35 psi when the tires are cold. There is also a tire pressure number shown on the sidewall of the tire itself. Don`t inflate your tires based on this pressure.
Tyres generally lose up to two pounds of air per month. This leads to your tyres quickly becoming under-inflated if you don`t keep an eye on them, making it crucial to perform a tyre pressure check once a month.
Is it Safe to Drive? If your tire pressure is only slightly low, you should be able to drive safely for a few more miles until you can add air. Tire pressure that is extremely low can lead to tire failure. This can result in a blowout, which can be extremely dangerous.
You don`t need to pull over immediately if you see it come on, but you should take action as soon as possible. If you`re on the highway or in heavy traffic, it`s generally safe to drive for a short distance (a few miles at most) to find a safe place to pull over and check your tires.
Ignoring the warning and driving with low-pressure tires causes them to flex more. It generates excess heat that overheats the tire components and causes them to wear and tear. The tires further experience excess friction, enhancing the tear and reducing their longevity.
Most passenger cars` psi requirement will be between 30 to 35 psi, but several vehicles fall outside of that range and every vehicle will have specific requirements. Good tire air pressure ensures that tires wear evenly, provide a smooth ride, and increase fuel efficiency.
When the tire pressure is low, the icon on your display screen will illuminate. You can also check your tire pressure yourself by removing each tire`s valve stem cap and using a tire pressure gauge on the valve stem.
Is 28 psi too low for tires? Most passenger car tires require 32 psi to 35 psi, so, yes, 28 psi is too low for tire pressure. Make sure each tire is filled with the proper pressure and that the stem caps are put back on securely afterwards.
As soon as you begin driving, friction warms your tires, increasing the pressure. Technically, any PSI below the recommended number is too low. However, most consider a variance of more than ten percent to be too low. For a car requiring tire inflation to 35 PSI, a reading of 31 or 32 PSI is considered underinflated.
Check and Adjust First Thing In The Morning.

This must be done before rising ambient temperatures, the sun`s radiant heat or even driving short distances temporarily warms the tires.

Tire manufacturers suggest checking tires when they`re cold for the most accurate reading. Outside temperatures can cause tire pressure to vary by as much as 1 psi per 10 degrees; higher temperatures mean higher psi readings. “Tires are black; what does black do?
Recheck the inflation pressure when the tires are cold. After filling your tires, use the gauge to check pressure again. At this point, it`s ok if you overfilled the tires because you can always let some air back out. Never drive on overinflated tires.
As inflation tends to drop with the temperature in cold weather, it`s important to check tire inflation every two weeks.

Advice for winter tires
ANSWER : 205/55R17 may be too tall for your vehicle. A couple of good sources to check size compatibility for your vehicle would be tirerack.com or maybe discounttire.com. Sites like Tire Rack specialize in winter tire packages and is a good source for fitment options. I have personally used Bridgestone and Dunlop snow tires and would recommend either. However, it is highly recommended that winter tires be mounted at all 4 corners. Having different tires with different capabilities not only makes the vehicle unstable, it will effect systems like the anti-lock brakes and traction control. Winter tires perform much better than summer or all-season tires do in ice and snow conditions. Having two tires with good winter traction and two with poor traction will have the anti-lock brake system working overtime. Also, sticking with a smaller tire for winter use is advisable. For ice and snow driving, you want the opposite for summer driving. Wide, low profile tires improve warm, dry weather driving. Tall, narrow, tires provide better control on snow and ice. Consider keeping your stock 16 inch wheels for winter use with winter tires mounted on them and maybe a nice set of 17 inch wheels and tires for summer use. I’ve done that with nearly every vehicle I’ve owned whether front, rear, or all-wheel drive.

Can I replace my 225/45R18 tires with 215/55R17 tires? The 215’s are what ALL tire sites say are original factory size
ANSWER : I owned a 2008 Sonata and currently own a 2015 Sonata Sport 2.0T Limited. With your generation as well as my 2015, the Sonata with the 2.0T engine has larger brakes so the 18 inch wheels make more room for them. Since yours is a 2.4 Limited, it only has the 18 inch wheels for appearance as all 2.4 ltr versions whether Base or Limited, have the same size brakes. I do not recommend a 215mm section width with the 18 inch wheels. The ride and handling will deteriorate badly. If you are sticking with the 18 inch wheels, then stick with the 225/45R18 tires. You can most certainly change down to the 215/55R17 tires AND wheels. Any 17 inch wheels listed for the Base, SE, GLS, etc will fit fine. The ride and handling will be different. It will ride a bit smoother as you are increasing the sidewall aspect ratio – 55 vs 45%. The will also be narrower – 215mm vs 225 mm. It may not grip as well in dry weather but you may notice a little better traction in wet and snowy conditions as there will be more weight concentrated on a narrower tread area. Your speedometer may be slightly off however. The average overall diameter of a 225/45R18 tire is 25.9 inches. So that makes for roughly 802 revolutions per mile. The 215/55R17 will have an average diameter of 26.3 inches and approximately 790 revolutions per mile. A slight difference that may only cause your speedometer to be off by 1-2 mph. On the up side, you may get a slight bump in miles per gallon. The taller tire will reduce engine rpms at highway speeds slightly. So if you are willing to reduce the wheels from 18 inch to 17 inch, then go ahead with the 215/55R17 tires. If you are keeping the 18 inch wheels, then stick with the 225/45R18 tires.

Inside edge of tires wearing out too fast
ANSWER : There is a technical bulletin from the manufacture to check the alignment camber, and if the camber is out of specification, replace the right rear lower control arm to correct the alignment. As far as the other tires, you should have the complete system alignment checked, and if out of adjustment then the suspension checked for damage or worn out parts. Your camber is out of adjustment if it is wearing on the inside or outside of the tires. Make sure you get the alignment done at a place that has a state of the art newer machine, and not some old machine that may make things worse than they are now. Alignments need to be very precise to keep the tires from abnormal wear.

How can tires inflated right and feel firm look like they’re low on air?
ANSWER : Your vehicle uses 60 series tires which are relatively low profile. That, combined with the fact that all modern passenger vehicle tires are radial tires, can make it appear as if the tire is low on air and the wheel is "too" close to the pavement even as everything is normal in terms of air pressure. It is easy to confirm what the status of the tires is using an ordinary air pressure gauge. Check your pressures against the required tire pressures that are printed on a label that is on the pillar surrounding the front door. Now that winter has arrived, just remember that for every drop of 10 degrees in the outdoor temperature the air pressure in your tires drops by 1 pound per square inch (psi). So, if you checked your air pressure on a nice sunny Saturday and it was 50 degrees outside, if two weeks later, it is 10 degrees, the air pressure in your tires will have dropped by 4 PSI. It’s burdensome to keep adjusting the pressure, so the best thing to do is assume temperatures will be at some average over the winter and adjust accordingly. The other thing of importance is to regularly rotate your tires. If you desire tire rotation, you can request that service from YourMechanic.

I hear a loud clicking noise on the drivers side by my tire rim when turning the steering wheel front tires vibrating as well.
ANSWER : A clicking noise on turning is very characteristic of a failed outboard CV axle joint. Sometimes, in such a circumstance, you can see that the rubber outboard boot is actually torn and leaking grease. If you see that (look behind the wheel toward the axle end), the axle for sure will have to be serviced. If you change the axle, be sure to install a new rubber seal on the transmission output side so that you do not have transmission fluid leaks with the new axle (a common mistake is to overlook that seal; if an old, left-in-place seal leaks after the axle is put in the job has to be done all over again). Vibration without actual shaking of the steering wheel "might" be related to the axle issue. On the other hand, such vibration could also be due to a failed wheel bearing, especially with over 200,000 miles on the vehicle and if those are the original bearings. If you were to need both an axle and a wheel bearing at the same time, and on the same side, that’s actually not that bad because the steering knuckle that holds the wheel bearing has to come off anyway to replace the axle. But, backing up here, the very first thing to do is get the issue properly diagnosed so you spend the minimum possible. If you want to obtain a diagnostic, please request a vehicle CV/wheel bearing noise inspection and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Repairing my flat tire – 1999 Toyota Sienna
ANSWER : Most tire stores are not allowed to repair a tire with a plug anymore due to the possibility of damaging the internal cords of the tire. They would have to remove the tire and patch it from the inside. A tire should not be repaired if the puncture is less than one inch from the outer edge of the tread that meets the side wall of the tire. A patch will not be able to sit flat inside the tire if it is too close to the side wall and won’t stick, starting to leak soon after installation. A tire plug is considered a temporary repair and may not last very long. It will last an even shorter amount of time if it is in or near the side wall.

I recommend having a certified mechanic, such as one from YourMechanic, come to your location to determine if your vehicle is perfectly safe and suggest a course of action to rectify any issues that come to light.

Nail in tire was removed but tire did not lose air. Nail did not penetrate all the way thru. Is tire still safe?
ANSWER : Hey there. As long as you sprayed soapy water on the area and no leak was found then you should be okay to operate the car without too much worry. If there was a leak, you would begin to see air bubbles where air is purging out of the tire. I would still bring the car to a tire shop to double check and make sure that it is okay to drive on.

Cupped tires
ANSWER : Hi there:

Cupping on a tire is one of the more difficult items to diagnose; due to the multiple causes of cupping. In most cases, cupping is caused by suspension components like struts that are worn out; causing the tire to absorb more shock than it should. When you combine this with low air pressure, poor tire quality or certain driving methods; the tread on the tire will separate, causing the tire to "cup". The best way to pinpoint why your tires are cupping is to have a professional mobile mechanic complete a cupping on tires inspection.
