If you've ever glanced at a tyre and wondered what all those figures mean, you're not alone. But fear not; we're here to demystify the code!Tyre size notations typically follow a standard format, such as "265/70R16." The first number, in this case, 265, refers to the tyre's width in millimetres. It represents the distance between the sidewalls when the tyre is mounted on the recommended rim size. So, a more significant number means a wider tyre, while a smaller number indicates a narrower one.Diameter: the critical factor
Moving on to the following number, which in our example is 70. This represents the aspect ratio or the tyre's height as a percentage of its width. So, a tyre with an aspect ratio of 70 means that the size is 70% of the width. It's worth noting that the aspect ratio is vital as it influences the overall performance and handling of the tyre.But what about that letter "R"? Well, that signifies the tyre's construction type, with "R" standing for radial construction. Radial tyres are the most common on tractors today, offering excellent traction, fuel efficiency, and a comfortable ride.Width: finding the right balance
When selecting the right tyre size for your tractor, finding the right balance in terms of width is crucial. A wider tyre can provide better traction and stability, particularly in challenging terrains.
