PSI or ‘pounds per square inch’ is the numerical value that denotes the air pressure in the tyres of a vehicle. As a general rule, many, if not most vehicles’ operating manuals recommend tyre pressure between 31 to 35 PSI for optimum mileage, long life, and stability even at high speeds.
However, the above doesn’t always hold true, and it would be a good idea to go through your vehicle’s handbook prior to refilling the air in the tyres of your vehicle. In fact, with so many different types of vehicles both on and off the road along with a myriad different tyre options, your car’s handbook would be the best guide for refilling the tyre with the required tyre pressure.
Flat Tyres
Any tyre pressure that is under 20 PSI is considereda flat tyre. Using a vehicle when even one of the tyre’s PSI level is 20 or below, will lead to a risk of a blowout- especiallyif the vehicle is driven at a high speed.
Here, even a cursory visual inspection will show that a tyre needs to be refilled, and/or its puncture repaired. It will appear low with more of its body touching the ground than the other tyres on the vehicle.
Apart from that, should the vehicle start to drag in a certain direction or if it is slow to pick up speed, the odds are that its tyres needs to be refilled on an urgent basis.
In case the vehicles used for towingpurposes, you should check and see if the PSI requirements for a laden vehicle are greater than for regular use.
Trojan Tyres are the primary suppliers of all kinds of tyres for both on-road and off-road activities, and can be depended upon to provide high quality tyres for both heavy and light passenger vehicles.
