How to Check Tire Specifications?
2 Answers
Tire specifications can be found on the sidewall of the tire. Taking a 205/55R16 tire as an example, 205 represents the width of the tire, which refers to the part of the tire in contact with the ground; 55 represents the aspect ratio, which is the ratio of the height from the rim to the tread to the measured width of the tire's cross-section; R stands for radial tire; and 16 represents the tire size. Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. They are usually installed on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and maintaining the vehicle's driving performance.
When I first started checking my car tires myself, I didn't know how to find the tire specifications. Later, I found the easiest method is to squat beside the tire and look at its sidewall, where there's a large string of letters and numbers engraved, such as the common format like 205/55R16. If it's hard to see, just use your phone's flashlight to illuminate the sidewall text. Also, there's a trick with the door frame—open the driver's door, and the label on the door edge or B-pillar will indicate the original tire specifications. The vehicle parameters section in the last few pages of the owner's manual definitely lists it too; I'm in the habit of folding that page for easy reference. If you're really unsure, just visit an auto repair shop—they can point it out to you in seconds and even teach you how to read those parameters.
