Tire Height Chart – Understanding the Numbers

If you think nobody wants to understand tire height chart except for mechanics, you’re definitely wrong. As a car owner, you also need to understand the numbers in your tires as the time come when you’ll consider replacing them. You know, money is tough these days. Instead of paying the mechanic to get their fingers greasy replacing your tires you’ll probably decide to do it yourself. So, choosing the appropriate tires for your vehicles starts by learning the whole new language and it’s none other than the tire height size conversion.

The first step to understand tire height chart is to recognize the first letters. The truth is that there is a corresponding letter for every type of vehicle. P represents Passenger vehicle, LT means Light Truck, T means temporary spare and ST stands for Special Trailer. Next to the letter is the width measurement of the sidewalls. It usually comes in millimeters.

Tire Height Chart – Understanding the NumbersOn the other hand, the figure next to the width measurement is the ratio. What does ratio means? If you are new to this, the ration presents the percentage of the width. So, for example, your tire is P225/60. The ratio is 60 percent or 0.06 when converted in decimal. Last but not the least is the last letter seen separated by a slash. This letter represents the vehicle’s internal construction. So let’s say you have R, it represents radial or the commonly used type of tire. In addition to that, this figure also serves as indicator of the tire’s loading capacity. For example, your tire is labeled with Z, which means the vehicle can speed over 150kph.

Tire height chart is truly a helpful tool in determining the size of tire to buy. Using tires of different size can result to losing the vehicle’s balance and could affect the speed. However, the most common issue encountered by drivers when using inappropriate tires is that it affects the turning ration of the vehicle. If that is the case, the only solution is to use proper-sized tires.

Along with that, a larger tire can cause misreading on the speedometer. Larger tires have the tendency to rub the suspension. In that case, the speed reading you see on the speedometer might be different from your actual vehicle’s speed. You can rely on the owner’s manual for tire recommendations. But if you have no idea how, you can ask for a mechanic’s advice. Today, there are websites that allow users to determine the actually height sizes of their vehicles by inputting the basic information. These websites also feature tire height charts and tire height size calculators.

Don’t just jump into the conclusion of buying tires when you haven’t determined the height size of your car. As such, you may end up wasting your money and effort doing so. Car dealers sometimes do not educate their customers of such thing. As long as they get money out of their sales, that would be fine with them. As a practical customer, it’s your right to ask the tire specifications or whether the tires would fit on your vehicle or not.
