Choosing the right truck tyres can be difficult, especially having to take into consideration many variables, such as vehicle speed and handling. Also, an incorrect choice of tyres can mean less traction when needed. So, what do you have to consider when buying truck and lorry tyres? First of all, you have to determine and choose the right truck tyre size: you can find this information in three different places: in the vehicle manual, on the sticker inside the door and, of course, on the tyres themselves. After choosing the tyre size, you should look at two more features: performance on the road and safety. The tyres must adapt appropriately to the type of terrain and weather conditions that the truck will encounter most often. So the right truck tyres should be specific to the type of environment, whether hot or cold, wet or dry. Also, remember to always follow the manufacturer’s recommendations and only fit tyres which meant for your truck.
Truck and lorry tyres sizes
There are two types of size measurement: metric and flotation. Metric covers the majority of tyres people buy and it’s a bit more challenging to understand. Truck tyres sizes come in this form: 385/65R22.5. The first part (385) gives the section width. The section width (in millimetres), also called cross-section width, is the measurement of the tyre's width from its inner sidewall to its outer sidewall (excluding any protective ribs, decorations or raised letters) at the widest point. The second number is the aspect ratio. The aspect ratio describes the height of a tyre's sidewall as a percentage of the width of the tyre. For example, if the aspect ratio is 65 then it means that the height of the sidewall of a tyre is 65 percent of its width in measurement. The R means radial construction. A radial tyre allows the sidewall and the tread to function as two independent features of the tyre. A bias tyre consists of multiple rubber plies overlapping each other. The final number (22.5) is the wheel size. So this means that this tyre fits a 22.5 inch wheel. Now that we have the width, sidewall and wheel size, we can take all that together and get the height of the tyre. You take the sidewall size, add the wheel size and then add the sidewall size one more time: that gives us the height of the tyre.
