Have you ever tried reading your tire size? It looks like a jumbled mess, doesn’t it? Even though there’s a lot to take in, there’s actually a pretty useful and interesting meaning behind each and every aspect. To better explain, let’s take a look at an example:
P – stands for “passenger.” This is the Tire Type. Tires with “P” on them are designed to go on passenger vehicles – usually sedans and some light unibody SUV’s. Another thing you may see is “LT” (Light Truck) – this is usually put on big trucks like F350’s and some body-on-frame SUV’s.
245 – is the Tire Width in millimeters from sidewall-to-sidewall. This area generally encompasses all your tire’s tread. In our example, 245 means 245 millimeters.
55 – is the Aspect Ratio. This measures the height of the sidewall from where it meets the rim to the tread. In our example, 55 means the sidewall height is 55% of the tire width (which we said earlier was 245 millimeters.)
R – is the Construction. In our example we have a “R” tire – a radial – which means the tire layers run radially across the tire. Almost all tires on the road use this structure, but you may also see cross ply style tires.
16 – is the Wheel Diameter in inches. This is a simple measurement of the size of your wheel (sometimes called a rim) and in our example, the wheel size is 16 inches.
