Proper pumping not only increases road safety but also avoids premature tire wear and improves energy efficiency. Remember that an incorrect pressure level is the most common cause of tire damage. Find out this tire pressure guide to know how accurately do you care for the pressure in the wheel tires? When to pump tires and to what amount.
Each car manufacturer defines the essential parameters of rims and tires that can be used in a given car.
First of all, the parameters determine the size of the tires (recommended and optimal), the diameter of the rims and the method of fixing them (number and spacing of bolts).
Why is the right tire pressure so significant? Because the air filling the tire and ensures its proper shape, and also carries the weight of the car. Thanks to it the tire can stay on the rim. Both low and too high pressures are harmful.

Why Is Tire Pressure Important?
Tire pressure affects driving, cornering, braking, and fuel consumption – everything that should be important to you. A tire with the incorrect pressure will wear out faster and may pose a threat to your safety. Improper tire pressure level can seriously threaten your protection and also expose you to measurable financial losses:
- Faster tire wear.
- Longer braking distance.
- Worse road holding and less control over the vehicle.
- Higher risk of aquaplaning.
- Higher fuel consumption.
- Too much-inflated tires swelling, which limits their contact area with the ground, and consequently reduces the adhesion and the ability to cushion unevenness. In this case, the tread will wear much faster in the middle zone.
On the contrary, if the amount of pressure is too low, the lateral walls of the tire are subjected to heavy loads, which leads to overheating of the rubber and may result in a dangerous breakage of the wheel and loss of control of the vehicle. However, before this happens, you will surely realize that your car is burning more and worse on the road, especially on wet roads.
The tires are losing pressure all the time. Even under ideal conditions, the pressure drops by about 0.069 bar or 10 psi per month. This value increases with increasing temperature.
For this reason, regularly check the tire pressure using the best tire pressure gauge at least once a month.
Recommended Tire Pressure Chart for Cars
Recommended pressure values can be found in the car’s service manual, and on some vehicle models inside of the driver’s door or under the fuel filler flap.Sometimes the manufacturers recommend different pressure for the car front and rear wheel tires. The most important thing is that the tires on the same axle are inflated equally.
In some cases, slightly higher pressure should be used. If you are pulling a trailer, inflate the rear wheels by 0.5 to 0.8 bar. In winter, pump all tires 0.2 bar above the recommended value to compensate for the pressure drop caused by the lower temperature.

Where Can I Find The Recommended Pressure Values For My Tires?
- In the instructions provided by the vehicle manufacturer.
- On the sticker on the driver’s door or on the door to the fuel tank.
- Do not use the number on the tire sidewall because it does not provide the tire pressure guide.
How to Control the Tire Pressure
A certified tire pressure gauge should be purchased, or the vehicle can be taken to a nearby service center (or a petrol station) for inspection.Tires must be controlled in a “cold” condition (the fastest three hours after the end of the ride).Insert the pressure gauge into the valve.
Compare the measured tire pressure level with the value indicated on the car door.If the measured value is higher, let the air be released until its level matches the value given on the car door.If the measured value is lower, the air should be inflated until the level corresponds to the cost given on the car door.
How Low Tire Pressure Harm Your Wheel Rim and Tire?
Too low tire pressure has several adverse effects. Let’s start with the most important ones that have an impact on car safety. Under-inflated tires cause improper behavior on the road when maneuvers, especially sudden. The braking distance is significantly longer. The car is also more prone to slip understeer or oversteer on a slippery surface. While driving, the tire may fire.Too low pressure in the tires hinders the proper operation of advanced safety systems, such as ABS (anti-lock braking system), ASR (anti-slip system) or ESP (anti-slip system understeering and oversteering). All of these systems operate based on wheel speed sensors. The wheel, in which there is less air, turns differently than the others.
The situation in which there is little air in the tire is hazardous for the durability of tires and rims. Accelerated tread wear occurs, and with a tremendous loss, the rims can cut the tire. This can lead to damage to the rims, which may be irreversible (repair will be impossible, it will be necessary to purchase a new rim).Too low air pressure in the tire reduces driving comfort – the car can pull into one of the sides or give swimming skills (when losing air in the back).The reason for too low pressure may be its puncture. It is more comfortable and more convenient to repair them with the help of a tire foam.
How High Tire Pressure Harm Your Car Tire?
Too high a tire pressure, more significant than recommended by the manufacturer, is also harmful. First of all, it is dangerous because it reduces adhesion. This is because the smaller surface of the tire is in contact with the road surface. Exactly, it’s a middle part. Moreover, this central part is also consumed the fastest. The tire is also noisier when driving, and more susceptible to damage due to uneven surfaces.
Why You Always Maintain Right Tire Pressure?
The tire loses some of its pressure from natural causes (typically around one psi (0.076 bar) per month). A pressure loss can accelerate leaks due to:
- Accidental puncture.
- Valve operation: the valve should be replaced whenever changing tires .
- valve nut: is crucial for valve tightness.
- wheel: clean each time a tire changes.
Follow the vehicle or tire manufacturer’s instructions, especially regarding conditions of use (load capacity/speed, etc.).
Monitor the tire air pressure when the car tires are cold (tires that have not been used in the last 2 hours or have been driven less than 2 miles (3 km) at low speed).
If the pressure is checked in hot tires, add 4-5 psi (0.3 bar) to the pressure recommended by the vehicle manufacturer. After the tire has cooled down, the pressure should be rechecked.
Do not release air from the hot tire.Even if the tires are filled with nitrogen, the pressure and general condition of the tires still need to be checked frequently.
A properly inflated tire increases safety, is more economical to use and better for the environment.
How do you check the air pressure in the tire?
- Insert the digital tire pressure gauge into the tire valve stem.
- The tool “pops out” and displays the value corresponding to the internal pressure in psi.
- The hissing sound means that the air escapes from the tire. This should not significantly affect the pressure unless you hold the air pressure gauge too long.
- Compare the measured value in psi with the recommended one.
- If the value in psi exceeds the recommended value, drain the air until it is even. If it is lower, inflate the tire by best cordless tire inflator until the values are even.
About Air Pressure Indicators
- Use caution when using the manometer in the service station. Often their measurements are inaccurate.
- Buy a high-quality pressure gauge and check its accuracy with a tire specialist.
Consumption: fuel Consumption And Co2 Emissions
Tire inflated to 80% may suffice for a 20% shorter. This means a loss of 5,000 miles (8,000 km) on a potential mileage of 25,000 miles (40,000 km).
Low tire pressures resulting in both increased fuel consumption and carbon dioxide emissions.
What Is Nitrogen?
Nitrogen is simply dry air, from which oxygen has been removed. The air contains almost 79% nitrogen.
How To You Use Nitrogen In Car Tire?
- Most tires are filled with compressed air. But some sellers have started to pump their tires with nitrogen.
- Nitrogen and compressed air can be mixed.
- Most tires can be inflated with air or nitrogen as long as the pressure values recommended by the vehicle manufacturer are complied with.
When nitrogen replaces oxygen, less air escapes from the tires, and the pressure stays longer.
Tire Air Pressure Control:
Unfortunately, there are other possible leak points (tire/rim contact, valve, valve/rim contact, and wheel), So there is no guarantee that the pressure will be maintained either with air or nitrogen. The tire air pressure and overall tire condition should be checked frequently.
What Is The Role Of The Valve In The Tire?
- This ensures that the correct tire pressure is maintained.
- It blocks the ingress of moisture into the tire.
- Particularly noteworthy is the valve nut, which prevents particles of dust and dust from blocking the valve. It is recommended to use high-quality nuts.
Aging and damage
- Valves are usually made of rubber and thus age over time.
- Valves are usually made of rubber and thus age over time.They can also be damaged by high speeds, which will cause air leaks from the tires.
Final Verdict: The Tire Pressure Guide
Tires with too low or too high air pressure can wear faster than expected, have reduced traction and can result in higher fuel consumption. Ensuring the safety and durability of tires takes only a few minutes per month.By maintaining the correct tire pressure, you reduce operating costs. Too low air pressure in the tires causes susceptibility to overheating, higher fuel consumption and faster wear of the tire itself. Similarly, excessive tire pressure can shorten its service life and cause control problems.
Obviously keep a tire inflator with gauge in your car emergency kit checklist.
