It is imperative for you to know the size of your tires if you wish to make an informed tire purchase. More often than not, you can easily find the factory tire size of your car in your owner’s manual.
Or, you can also search for the details on the glove box lid, on the driver’s door edge, or inside the fuel hatch.
However, there are several important factors or rather, terms, you need to be familiar with if you want to choose the right tire for your car.
For instance, you need to identify the tire width, the aspect ratio between the tire height and width, wheel diameter, load index of the tire, speed rating, and see if it has a mud and snow rating.
Not all tires are created the same and the size of the tires on your vehicle largely depends on the model of your vehicle. For instance, van tires can have a width of 275 millimeters, while a normal four-door sedan can have a width of 215 millimeters.
However, it should be brought to notice that bigger tires don’t necessarily correlate to bigger vehicles. Many people tend to install larger tires for aesthetic purposes too.
Of course, the size of the tire plays an instrumental role in adding to the overall appearance of a car. But they can also affect performance.
For instance, smaller tires offer quieter rides and better impact resistance in uneven surfaces. There is also less risk of hydroplaning on smaller tires.
Larger tires give better grip, improved braking and cornering performance. On the downside, larger tires wear faster. Understandably, smaller tires are also less expensive than larger tires.
When choosing a tire, it is ill-advised for you to opt for a tire that is smaller in size than the original tire of your car. It is always advisable for you to consult with an expert if you wish to install tires that are larger or smaller than the vehicle’s original tire size.
In order to find the right tire size, you will need to check your tire’s sidewall for a series of numbers.
The numbers will indicate several important factors including the tire type (whether it is a passenger car tire or a light truck tire), tire width, aspect ratio, construction of the tire, rim diameter, load index of the tire (indicating the load carrying capacity of the tire), and speed rating.
Fortunately, there isn’t a dearth of tire stores in New Jersey that can help you with your readings.
