Maintaining a tire is one of the most vital things a driver can do for safety reasons. One of the simplest methods of caring for your tires is to maintain the correct tire pressure. This simply means that overfilling your tires could be as dangerous as under-filling it too.

However, it’s vital to know the recommended pressure for your car.

In case you always ask what is best tire pressure for highway driving, then note that the recommended pressure for tire ranges between 30 and 35 PSI.

Recommended Tire Pressure 44 Psi Max

Anytime you noticed that your tire has reached its maximum tire pressure which is 44 psi, then note that it’s not compulsory to fill it up.

Normally, it’s good for tire pressure to remain in a lower level than the maximum pressure which is seen on the tire.

So what does psi stand for pressure?

The psi simply stands for pounds per square inch. When you see 2psi, its shows that the air inside the tire is at 2 pound per square inch of pressure.

However, the quality of a road sometimes determines tire pressure. So in case you are planning on going on an off-road type of trip, you can then lower your car pressure.

What Does It Mean When A Tire Says 44 Psi Max?

It simply means that the 44 psi is at the max inflation of the tire load rate. But I advise you to keep a pressure of about 10% to 15% under the maximum psi rating, if you want your tire to reach its peak performance rate.

What Is The Recommended Tire Pressure For 40 Psi Max?

The sticker or card which can be seen close to the driver’s door is where to find the original tire pressure for most vehicles. But  you couldn’t find  the recommendation tire pressure sticker there, then check on the owner’s manual. However, the recommended tire pressure should be around 32-40 psi.

Is 45 Psi Too Much Air?

It is known that making use of too much or too low tire pressure will compromise tire wear, handling, and comfort. However, 99% of the time, 45 psi is simply too high.

The figure you see on the tire doesn’t have anything to do with driving, but car maximum load. Every vehicle comes with its own recommendation, which is normally seen inside the door frame.

How Do You Know If You Put Too Much Air In Your Tires

It is very vital to take good care of your tires and also understand when you put too much air in your tires

Here are 4 signs to know if there are too much air in your tire

1. Lack Of Traction

Losing traction happens to be the first sign that you will notice in your tires whenever there’s too much air.

This is because the contact patch happens to be what gives your vehicle the grip.

The Smaller Contact Patch

The loss of grip happen as the contact patch gets smaller; this means that the grip that’s available is too small.

You will start noticing the car want to slide slowly as you drive around corners, or sometimes you will notice that there’s an increase in braking distance.

So ensure you regularly inspect the tire treads, instead of waiting to see what handling looks like while driving.

2. Excessive Wear on Center Treads

Whenever you check the tire treads regularly, you’ll start observing when the center treads become worn out.

Also, you will notice if its more significant with the ones inside and outside of the tire.

In case you’ve been driving with too much air on the tires for a while, then it means center treads is likely to have been doing most of the work when looking at the contact patch.

This means that it will likely be far more worn than the surrounding treads.

Legal Tread Limits

Note that there are legal limits when looking at how much tread a vehicle must have on the tires. However, this is measured by depth, which is across the full tire.

This means once you have too much tread on the inside and outside of the tire, once the center treads are worn out beyond the limit then you could be breaking the law.

You should understand that treads are vital for grip and safety, so you shouldn’t be driving illegally.

3. Having An Uncomfortable Ride

You’ll observe a more uncomfortable ride whenever you have too much air in your tires, along with a potential decrease in grip.

However, this is due to an over-inflated tires which can be stiffer and are not flexible when compared to those filled to their correct pressure.

This is because stiffer tires transfers lots of bumps from the road which affects you and your passengers.

 But an inflated tire that’s in correct pressure will absorb more of the shock.

Extremely Uncomfortable

Note that you will not really notice this like when you drive with a broken suspension system for instance, but when you spend more time driving on uneven surfaces then you will definitely observe it more.

Whenever you are driving in high speeds, this will ensure you notice less bumps in the road. While it might not be dangerous, you will be very uncomfortable.

4. The Car Behaving Abnormal

Apart from having loss of traction or your car been uncomfortable to drive, you’ll also notice its abnormal behavior than the way you are used to.

This is due to systems such as the traction control and ABS that are tuned to work with the tires which are filled with the right amount of air.

Not Designed For It

Whenever your tires are overfill, the electronic stability control systems found in your car might start acting weird, as they may pick up signals that are not right from the wheels, and this could make it to try controlling the car in an uncomfortable way.

However, note that this can be very dangerous, and this is another reason why you should make sure to always fill your car tires with the correct amount of air pressure.
