Tires are the shoes of the automobile and the wheels are the legs, having great legs is important but ask any woman shoes can change the world. On average a person will spend more on shoes for their feet than on tires for the car they drive. The C/V axles, the ABS control module, the control arms…literally every system in the car relies on the tires to keep everything in check. Ever seen one of those worlds wildest police videos what happens when the cops shoot out the tires? Does anyone ever get far without tires? No, they have to book it on foot. After a good set of tires the vehicles alignment is the next step to vehicle care.

The following information should help to explain what is being checked on your car.

Tire Width

Tire Width is the width of the tire measured in millimeters from sidewall to sidewall. The first three-digit number in the tire size refers to the tire width. For instance, in a size P215/65 R15 tire, the width is 215 millimeters.

Aspect Ratio

Aspect Ratio is the ratio of the height of the tire's cross-section to its width. The two-digit number after the slash mark in a tire size is the aspect ratio. For example, in a size P215/65 R15 tire, the 65 means that the height is equal to 65% of the tire's width. The bigger the aspect ratio, the bigger the tire's sidewall will be.



The letter "R" in a tire size stands for Radial, which means the layers run radially across the tire.

Wheel Diameter

Wheel Diameter is the size of the wheel measured from one end to the other. It tells us the size of the wheel that the tire is intended to fit. A size P215/65 R15 tire is made for a wheel with a 15" diameter.

Load Index

Load Index indicates the maximum load that the tire can support when properly inflated. You'll also find the maximum load on the tire sidewall, in both pounds and kilograms.

Speed Rating

Speed Rating tells you the maximum speed capability of a tire. Often speed ratings are matched to the top speed capability of the vehicle. For example, a tire with an H-speed rating has a maximum speed capability of 130 mph or 210 km/h. Paradigm Automotive does NOT recommend exceeding legally posted speed limits.
