225 35 ZR19 88Y: What Does the Code Mean?
225: Tire Width
The first number on your tire indicates the width, in millimeters. In our example, the tire is 225 millimeters wide. Sounds logical, right?
35: Aspect Ratio
The second number, separated by a slash, describes the aspect ratio. This is the ratio of the tire’s height to its width, expressed as a percentage. In our case, the aspect ratio is 35%. This means the tire height is 35% of the tire width (225 mm), which is 78.75 millimeters.
Small Tip: A lower aspect ratio means a sportier look and more direct steering response, but also reduced ride comfort.
ZR: Tire Construction Type
The letter combination ZR stands for a Radial tire construction. Almost all modern tires are radial tires, so you’ll see this marking frequently.
19: Rim Diameter
This number indicates the diameter of the rim in inches that the tire fits onto. In our case, it’s a 19-inch rim.
88: Load Index
The load index, in this case 88, indicates the maximum load capacity of a tire at a specific inflation pressure. You can find a table with the corresponding values, for example, on the tire manufacturer’s website.
Important: Always ensure that the load index of your tires matches the permissible axle load of your vehicle!
Y: Speed Index
The last letter stands for the speed index and indicates the maximum permissible speed a tire can withstand. The index Y stands for a maximum speed of 300 km/h.
Warning: Never exceed the maximum speed specified by the speed index of your tires!
