Tire Pressure

Many drivers wonder why vehicle manufacturers use different size tires on their vehicles. Contrary to some thinking, the choice to include smaller or larger tires has nothing to do with making more money. Vehicles are evaluated based on their gross axle weight and the anticipated use of the tires. Some adjustments are made during engineering of a vehicle to improve handling and appearance. Some vehicles may be able to several different tire sizes depending on the manufacturer’s specifications. However, regardless of the tire size on your vehicle, to ensure you get the most performance, it is important to ensure the tires are properly inflated. Not only will this keep your vehicle performing effectively but it will also ensure you will have a safer ride. One major benefit to having properly inflated tires is better gas mileage. Tires that are underinflated will increase the amount of friction on the road. Having a tire with less than the recommended amount of air causes more of the tire to come into contact with the road. This causes more of the tire to drag, thus increasing friction and causing the engine to work harder. The harder the engine works the more gas you burn.

It also results in the tires overheating and wearing prematurely.

Additionally, tires without the correct tire pressure will affect your vehicle’s ability to brake effectively and to take corners properly. This could result in accidents and dangerous driving conditions depending on your speed and road conditions at the time. Overinflating tires will cause your vehicle to bounce around on the road. It will also result in the centre portion of your tire wearing prematurely because overinflated tires tend to prevent the edges of the tires from coming into contact with the pavement. This will impact the comfort of your ride and result in more tire damage due to punctures and road hazards.

The more bounce that occurs the more likely your vehicle will suffer damage to suspension components and steering components. This could result in a ride that is less than comfortable and more dangerous. A properly inflated tire allows the engine to work efficiently, reducing the amount of gas you burn as your drive. This reduces the exhaust emissions which is great for both the environment and your emissions system. Maintaining the proper air pressure in your vehicle’s tires is an essential maintenance item that takes only seconds for drivers to check. Use the manufacturer’s specifications for tire pressure located on the inside of the drivers door, inside the glove component or in the owners manual.
