What is the 50 in tire size?
The "50" in a tire size refers to the aspect ratio of the tire. Tire size is typically expressed in a format like "205/50R16", where the first number (205) represents the tire's width in millimeters, the second number (50) is the aspect ratio, and the last number (16) is the wheel diameter in inches. The aspect ratio is the ratio of the tire's sidewall height to the tread width, expressed as a percentage.
What is Tire Aspect Ratio?
The aspect ratio of a tire is the ratio of the tire's sidewall height to the tread width, expressed as a percentage. In the example tire size of "205/50R16", the "50" means the sidewall height is 50% of the tread width. A lower aspect ratio, like 50, indicates a shorter and stiffer sidewall, while a higher aspect ratio, like 70, means a taller and more flexible sidewall.
Why Does Aspect Ratio Matter?
- Handling and Responsiveness: Lower aspect ratio tires (like 50) provide more responsive and sporty handling, as the shorter sidewall allows for less flex and better steering precision. This makes them popular on performance-oriented vehicles.
- Ride Comfort: Higher aspect ratio tires (like 70) have taller sidewalls that provide a more comfortable, cushioned ride, making them better suited for comfort-focused vehicles.
- Wheel Size: The aspect ratio also determines the overall diameter of the tire, which must match the wheel size. Lower aspect ratios require smaller wheel diameters to maintain the same overall tire diameter.
In summary, the "50" in a tire size refers to the aspect ratio, which is the ratio of the tire's sidewall height to the tread width. This aspect ratio impacts the tire's handling, ride comfort, and compatibility with wheel sizes.

However, they refer to different aspects of these dimensions: 33 inches is a diameter measurement, while 285 refers to width. A 33-inch tire and a 285 tire can be the same if the 285 tire's aspect ratio and wheel size combine to give an overall diameter of around 33 inches.
Can I fit 55 profile tyres instead of 50?
Can I fit a different size than the approved ones? It is imperative to respect the sizes approved by the manufacturer. In some countries, an exemption is possible provided that the tyre diameter remains within a limit of no more than -2% and +1.5%.

Is a 50 tire wider than a 60?
For example, a 60-series tire features a sidewall that is 60% as tall as the tire's section width. A 50-series tire will feature a shorter sidewall, at 50% of section width. A 35-series tire will feature an extremely short sidewall (only 35% of section width), etc.
Is 50 considered low profile tires?
Typically, low profile tyres have an aspect ratio of 50 or lower. This means that the height of the tyre's sidewall is only half or less than the width of the tyre.
Can I put 55 tires instead of 50?
There is not a whole lot of difference between a 50 and 55 series tire in terms of ride or handing. You may not notice any difference at all, depending on the composition and construction of the tires themselves.
