These tyres fit several different makes and models of trucks. 10.00R20 tyres have a section width of 10 inches, while the final 0 signifies that they have an aspect ratio of 92%. The aspect ratio is the height of the tyre in comparison to its width. The R lets you know that these tyres are made with radial ply construction, while the 20 symbolises that they fit wheel rims that are 20 inches in diameter.
Tyres have a further aspect to their code, which indicates the maximum load capacity as well as the top speed that they are rated for. An example are 10.00 R20 146K tyres. These have a maximum load capacity of 3000kg for each tyre and can safely travel at speeds of up to 110km/h.
These 10.00 R20 tyres are often used in a range of different types of machinery, such as forklifts and tractors. Their large size and width makes them great for many different kinds of heavy duty work. This is why they are often used on farms or construction sites.
While 10.00R20 tyres can be great for a number of uses, some drivers may prefer an alternative size. A wider tyre will spread the weight out more, resulting in less impact on the ground covering.
