Is the Spare Tire a Tubeless Tire?

[DianaDella]

Tubeless tires are essentially vacuum tires, and currently, most small passenger vehicles are equipped with tubeless tires. Non-universal situations for tubeless tires: When the width is the same and the rim is the same, but the aspect ratio differs, the outer diameter of the tire changes. For example, 80/80 R11 and 80/90 R11 tubeless tires cannot be used interchangeably. This can cause discrepancies in speedometer readings. The principle when changing tires is to maintain the outer diameter of the tire as consistently as possible. Identifying tubeless tire specifications: Tire specifications can be found in the text on the sidewall of the tire. Currently, almost all passenger vehicle tires are radial tires. According to the radial passenger tire specification labeling method, they are marked in the order of tire width, aspect ratio, compatible rim diameter, load index, and speed rating. The XL suffix on a tire indicates that it is a reinforced load tire.
