Normal tire pressure assures the safety of your car, lifespan of tires, comfort, and even enhanced fuel economy.
It varies with the size of the car and its tires. Recommended tire pressure based on normal tire sizes usually 30 psi in small-sized cars, 36 psi in medium-sized cars, and 42 psi in large-sized cars.
The maintenance of tire pressure is cold inflation pressure, it means the pressure should be checked after the vehicle has been parked in the shade for a while.
Recommended Tire Pressure: How to Know?
- The owner’s manual of our car tells us normal tire pressure which is recommended by the car manufacturer.
- Generally we can found on a sticker pasted inside the driver’s door.
- It is measured in pounds per square inch (psi).
- You can also observe the sidewall of the tire, it lists a recommended tire pressure.
Importance of Recommended Tire Pressure
Recommended tire pressure assists to distribute evenly the weight of vehicle across the tread pattern of tire. It helps vehicle to increase its stability.
Some vehicles have unlike recommended tire pressures for the front and rear tires, usually higher pressure in rear tires, If you are carrying a heavy load.
Spare tire of our vehicle often loses tire pressure as air can leak out over time, as we don’t check its air pressure regularly. Unfortunately, sometimes spare tires mounted under the rear of the vehicle it makes a problem, as they may need to be removed to check the pressure.
Size of the tire pressure monitoring system market worldwide from 2018 to 2026
Have a look at the above statistics of tire pressure monitoring market, you will find a straight take off. Drivers have more awareness now. This industry will cross 23 Billion US Dollars in 2026.
Modern Tire Pressure Monitoring System
Direct Sensor Inside Tires
These are small, wireless gadgets inside each tire powered by software to describe the tire’s pressure reading on your dashboard. In this way you remain well aware all the time.
Indirect Sensors
These work by computing wheel rotation with waterproof hardware sensors and can only tell if a tire’s pressure is low.
Advantages of Properly Inflated Tires: Normal Tire Pressure
- Lower Emissions: Underinflated tires drop fuel efficiency for every missing PSI (pound per square inches). When low pressure remains in tires, your car burns more fuel resulting higher emissions.
- Improved Vehicle Handling: Proper inflated tires connect whole tread area evenly with road surface, it results stronger grip and better handling.
- Effective Braking: Underinflated tires can escalate stopping distances up to eight meters, in heavier vehicles it can be even more and duplicate in bad weathers.
- Greater Lifespan of Tires: Normal tire pressure ensures exceptional life of tires. Improperly inflated tires causes irregular tread wear resulting oversteer and understeer type issue.
- Recommended Rolling Resistance: Over-inflated tires decreases rolling resistance while under-inflated tires increases rolling resistance.
- 4 PSI Rule: Tire pressure should be about 4 PSI above the cold pressure, if not adjust pressure accordingly.
Disadvantages of Poor Tire Pressure
- Over-Inflated Tires: Greater risk of blowout / burst, also shape of tires deformed.
- Under-Inflated Tires: Premature tire wear, poor fuel economy, and reduced steering and braking ability, also more bending of tire. Tires heat up excessively resulting tread wear.
- Impacts on Suspension: Suspension become stiff with over-inflated tires and road shocks pass on to suspension system. While, under-inflated tires act as mini shock absorbers, resulting strains in suspension.
