Yes! 664 people died in 2020 in the USA due to tire-related car accidents only. In 2017 the number was 738.
This report was published by NSTSA in 2018 and the stats for last year is going to be published soon.
Most of those accidents happened due to tire pressure-related problems. One of them is excessive road noise from tires on the highway.
So, if you don’t want to be one of those unfortunate people, then keep the tire pressure in mind.
No worries. We’re here to cover you about tire pressure knowledge.
As you’ve asked, for 44 psi max tire pressure, you should maintain a 39.6 psi.
That’s not all! Here we’ll discuss-
- Tire pressure symptoms at different pressure
- Tire pressure guide for cars
- Consequences of low tire pressure
So, let’s the roll-on
Uneven Tire Pressure Effects
Uneven tire pressure can mean two things-
- The tires are over or underinflated
- All the tires don’t have the same pressure levels
Overinflated tires symptoms
Overinflated tires are not a good idea. You might lose temptation and over-inflate your tires. This can happen due to carelessness or inattentiveness.
So, how do recognize over-inflated tires?
You’ll need to look out for 3 symptoms.
- You’ll get less traction.
- The ride will become harsh and noisy
- Your tire will start wearing on the center
There is a saying that, if all of your ties have coffee marks on them, then you have over-inflated tires.
Due to overinflation, the tire gets an oval-like shape. For this shape, the tire sides curve up, letting only the center touch the road. Eventually, the tire gets uneven wear. And soon the tire becomes unusable.
Underinflated tires symptoms
Underinflated tires will cause almost opposite symptoms. In under-inflated tires, you’ll also have three symptoms.
- Tire wears on the sideways
- Tire performance will decrease
- Safety becomes questionable
You will certainly get a comfortable ride on bumpy roads, but the tire might not respond properly to a hard brake. Also, you’ll notice uneven wear on the sideways.
Similar Tires Pressure
Should all tires have the same pressure?
If all your car tires don’t have equal pressure, then it’s also problematic. The logic behind this claim is pretty simple.
Let’s figure this out with 3 scenarios.
Scenario 1: Only one of your tires has low pressure. So, that tire starts carrying more than its required weight. As a result, that tire wears out quickly.
Scenario 2: Only one of your tires has high pressure. So, that corner would be a little elevated. This will make driving a bit uncomfortable. One corner of the car will become bumpier.
Scenario 3: Two of your tires are under-inflated or over-inflated. The car becomes a bit down or elevated on one side. So, tires on that side carry more weight. As a result, tires wear at a quicker rate than average.
So, maintain a uniform pressure among the four tires.
What is the optimal tire pressure for a tire with 44 psi max?
If your tire has written on it ‘maximum tire pressure 44 psi’ then it’s not a must for you to fill up this criterion.
The norm is that tire pressure should be kept at a little lower level than the max amount written on the tire.
So, measure your tire pressure when the tire is cold and adjust it around 39.6 to 40.04 psi.
Now, what does psi stand for pressure?
It means pounds per square inch. 1psi means the air inside the tire is putting 1 pound per square inch of pressure onto the tire wall.
But tire pressure also depends on road quality and everything. If you plan on going on an off-road kind of trip, then it’s better that you lower your car pressure. This is called ‘air downing’ by off-roaders.
During winter increase the pressure to 44 psi to get better traction. Air shrinks in cold temperatures. So, a few psi more would get your tire back to normal.
Tire Pressure Guide for Cars
What is normal tire pressure?
There is no definitive answer to that question. The best tire pressure for your car can differ from model to model. Factors like weight, the center of gravity, etc, play a role in determining optimal tire pressure.
The best tire pressure for your car is probably written on the tire pressure label of your car.
Usually, this placard is found on the driver-side doorjamb. This is called the ‘B-pillar’.
Older cars don’t have this B-pillar. In those cars, the label might be found on the rear edge of the driver’s door.
If the car is missing both the B-pillar and wide door edge, then you’ll probably find it on an inward-facing surface near the driver’s sitting position.
Although following the label is the best option but still, we’re suggesting a pressure guide.
So, here it goes-
|Recommended Tire Pressure (Max) (In psi)||Optimal (In Summer) (In psi)||Optimal (In Winter) (In psi)|
Generally, the rule of thumb is-
Optimal pressure = Recommended Maximum Tire Pressure – 10% of the recommended tire pressure.
Simply put, Optimal Pressure = 90% to 91% of the recommended tire pressure
But for winter, the pressure should be increased by 2-5 psi to keep better control.
- Keep a good tire pressure gauge in your tire. Pencil-style gauges are too inaccurate. On the other hand, dial-type gauges or digital gauges are pretty accurate.
- Install a tire pressure monitoring system. But don’t rely on these as these devices warn only when the tires are too underinflated.
- Check on a monthly basis.
- Check when there is a change in the weather. It’s suggested that tire pressure should be checked every 10 degrees of change in temperature.
Maintaining tire pressure is a crucial factor in safe driving. Tires cost a lot more than a quick pump or a quick pressure check.
So, maintain your tire pressure regularly, rotate your tires and check the wearing on a regular basis.
