Tyre Pressure Impacts Your Cars Performance More Than You Might Imagine

By Chad Ina - August 28, 2015

You own a great car, truck or motorcycle and you want the best mpg as possible, performance and lifespan, but if your tyres aren’t properly inflated you will jeopardise all of that plus the safety of your vehicle also.

At least once every fortnight to a month you should check the air pressure in your tyres. If you have a good tyre pressure gauge then it’s a 5 minute job. The rewards you’ll receive will be well worth it in the long run, trust me. Here are the big reasons you want to check your tyres’ pressure often:

1. Safety

If your tyres are under-inflated you can easily pop them right off the rim. When you’re driving at higher speeds this can be a lot worse than just getting a flat because the whole tyre generally de-laminates and shreds.

If your tyres are over-inflated you can’t get proper traction. This is especially dangerous where water and or oil are present. When it rains, oil mixes with the water on the road and this can spell big trouble.

2. Gas Mileage

If your tyres are under-inflated you’ll get terrible gas mileage It’s much like having shoes on your feet that are 3 sizes too big. Your feet flop around in there and you can’t generate forward momentum very easily. Just like your car expends more energy to travel the same distance which for a vehicle equals terrible gas mileage.

3. Engine Load

When your tyres are under inflated they are kind of like a bean bag with the weight of your car on them. They don’t roll like a normally pressurised tyre. Instead they are constantly conforming to the road. Because of this it’s like your car has to push your tyres and this creates a lot more work for your motor.

As a result you’re requiring considerably more engine power going the same speeds you normally drive at. This is putting undue stress and power demands on your car which can cause extra wear, parts failures and even engine failure if taken to extremes. Again, this is easily avoidable by just maintaining the correct tyre pressures.

4. Tyre Wear

If your tyres are under-inflated they are likely to wear out super fast. They are simply gripping the road to aggressively and the road is acting like sand paper sanding the rubber right off your tyres.

If they are over inflated then they won’t track properly and will wear very unevenly. If one edge of your tyre is basically bald then you have no choice, you have to get a new tyre. If not you risk a blowout at higher speeds.

5. Performance

Your tyres are your connection to the road. They are what your car uses to propel you, stop the car, corner and give you steering input. It is what is known as mechanical grip.

If your tyres are not at optimal pressures then you will not have optimal control and cannot have optimal performance, it’s as simple as that.

So, my advice to you is to get the best, most accurate pressure gauge money can buy as they are so cheap to start with. You’ll be glad you did.
