When it comes to your car’s smooth handling and performance on the road, tire pressure plays an important role. Poorly inflated tires can not only put the health of your rims and tires at risk but may also contribute to a life-threatening on-road accident, making it essential to keep the tires of your vehicle inflated all the time. Moreover, low-pressure tires also affect your car’s fuel efficiency while making your ride bumpy and uncomforting. However, all tires are bound to leak air, whether slowly or quickly; they’ll eventually lose pressure as you drive the car.
Reasons Why A Tire Loses Pressure
Due to osmosis, every tire loses pressure at a rate of 1-3 psi per month. A more robust leak, on the other hand, could well be a result of the following:
1. Wheel Issues
When it comes to vehicles, the only connection between the car and the road is its tires, and they’ve to bear all the pressure and get damaged. The two main problems that can cause tire pressure loss are:
Poor Stem Valves:
Due to exposure to various pollutants on the road, valve caps degrade and start leaking air. Typically, drivers receive a new set of wheels in addition to fresh tires. However, if a tire loses air above 1-3 psi each month, it may need to be replaced sooner. One of the causes of the leak could be overtightening valve stems. You’ll probably need to have a pre-set wrench because the pressure must be around 4 inches per pound.
Bent or Damaged Wheel:
A road hazard or corrosion may cause the wheel’s shape to change slightly. Air loss can be more severe if a breakdown occurs at the place where the tire mounts. A bent wheel may also increase vibration, which can cause damage to the tire’s bead and contribute to an air leak.
If you notice any of these problems, visit expert technicians at Camaro Workshop Abu Dhabi for a consultation to repair or replace the valve stem and tire if needed.
2. Tire Damage
As we all know that tires are the only connection between the vehicle and the ground, so they’re always at risk of losing air pressure due to:
Nails & Sharp Debris:
Nails can puncture tires easily and cause air leakage at rates of 2 to 3 psi per day. The nail can remain in the tire for a more extended period and cause air loss of insignificant proportions. However, you must still remove it as the leak can worsen if it’s not fixed immediately.
Wheel Bead Corrosion:
Air can leak from any surface that seals rubber and metal. Bead chunking is a small fragment of material between the tire’s rim and the tire. Tire air leaks can occur if your wheel is old or made with diecast metals susceptible to rust. You may get TPMS alerts if there is a small gap between your tire and the bead/flange of your metal wheel, or even the tire can end up flat in no time.
The tire may lose air pressure if you drive it over a large pothole or curb at a higher speed. The tire-wheel unit can survive more often than not, so all you’ll only need to do is re-inflate it. It would be best if you inspected the sidewall for bulges, tears, or punctures. These signs can indicate external or internal damage that may lead to the leak.
You should inspect your tires for any damage, such as a loss of air pressure or if you feel that it is time to visit a mechanic. You might be able to repair some of them, like a small puncture, but seeing an expert is always the safest option.
3. Temperature Changes
Temperature changes are one of the leading causes of tire pressure losses. Temperature changes impact tire pressure. Air nature contracts when it is cooled and expands when it is heated.
A temperature drop of 5.5°C can cause a tire to lose up to 2% of its air pressure. But it is possible to raise your tire pressure to 2% by increasing the temperature by 5.5 degrees Celsius.
This temperature variation can make it difficult to know if your tire pressures have returned to normal after you check them in the morning. If there are no damages to your tires, rims, or valves, you don’t have to add more air to tires, losing air pressure from temperature changes.
Fixing The Issue
These are the things you should do if your tire starts to lose air.
- Repair/Replace the Tire
- Repair the Valve Stem
- Repair/Replace the Rim.
An important thing to note here is that you can’t repair every damage to the tire or wheel. Some repairs can be temporary, and you will have to wait until the next tire shop. You should never use low-quality or quick maintenance regularly.
1. Repair The Tire
When it comes to repairing a punctured tire best thing to do is visit a workshop. But if you want to do it yourself, you will require a sealant and an air pump.
Place the sealant’s nose into the puncture area where the tire leaks air slowly. You should adjust the adhesive, so it is pouring on the inside of the tire, and run it until you can use the entire standard-sized bottle. It will serve as a protective coating inside your tire. The pressure from the pump will push the mixture into your hole. The rubber-like plug will seal your tire in place. You can choose between pre- or post-puncture sealants, which is helpful if your tire leaks the air slowly.
2. Repairing the Valve Stem
In case your tire’s valve stem is leaking the air, you’ll need a valve removal tool, as well as a replacement core. To remove the wheel, you will need a carjack and a wrench.
You can remove the valve core from the tire where it leaks air by putting your removal tooltip in the stem and rotating it anticlockwise. Make sure you clean the valve stem properly if there are any signs of corrosion. Then attach the new core to the tire and turn it on.
3. Repairing or Replacing The Rim
Suppose you drove off a pothole at a higher speed, and the result is far from ideal in the shape of a bent wheel. In that case, you should visit Porsche Workshop in Abu Dhabi and get hydraulic assistance to help you straighten the wheel with greater efficiency.
Do anything you want but try to repair the bend on your own, as hammering your alloys will only result in breaking them. What you can do is protect the wheel from corrosion by cleaning it at least once a week. Another option is to replace the alloy with a brand new one and be careful of the potholes you take the car out on the road the next time.
