Before you buy a truck tyre, you must know about truck tyre terminology. One of the most effective methods in today’s world is reading, studying, and having a small amount of knowledge before purchasing anything. The same criterion applies when purchasing commercial truck tyres. In particular commercial truck tyres in Liverpool are more complex than passenger vehicle tyres. But, to make things easier, the list of things mentioned here are the most crucial points to remember about commercial truck tyres.
The cross-sectional width of a tire:
For example, 295/80 R22.5, the first three digits 295 denote the tyre’s cross-sectional width in millimetres. The inner to outer sidewall’s broadest point makes up the entire width.
The aspect ratio of tires:
The tyre’s aspect ratio or profile value will appear after the slash mark in the example above. The two-digit number, 80, denotes the proportion of the sidewall’s height to its width. This means the distance between the wheel rim and the outside of the tread.
Construction of tires:
Three symbols usually indicate the construction type of the tyre: R, D, and B. Take the previous example (295/80 R22.5), where the ‘R’ denotes radial construction. Furthermore, a ‘D’ indicates bias-ply construction, whereas a ‘B’ indicates belted tyre construction.
Size and diameter of wheels:
The tyre wheel and diameter in inches are represented by the last two numerals, followed by the construction symbol. The larger the number, the bigger the tyre’s wheel size will be. The 22.5 at the end of 295/80 R22.5 indicates that a 22.5-inch diameter wheel is required.
Ply rating or tyre load range:
A digit and alphabet, followed by the tyre size, can be found on various commercial truck tyres in Liverpool. The ’18’ in 315/80 R22.5 156/150L 18PR, for example, denotes the tyre’s ‘Ply Rating.’ The load range letters for commercial trucks, which have greater load-carrying requirements, are F through L. The load pressure rises by 15 psi as the letter increases. They rise from 35 psi to 95 psi.
Speed rating and load index:
The load index and speed rating are represented by a letter and a double-digit numeric value. The 150/156 specifies the tyre’s load index, while the L indicates the maximum speed it should be utilised, as in the 315/80 R22.5 150/156L dual fitment tyre. The load index 156 indicates that the tyre can carry a maximum load capacity of 4000kg in a single fitment. In contrast, the load index 150 indicates that the tyre can carry a maximum capacity of 3350kg in the dual fitting. With the specified load, the L in the tyre size indicates that it can attain the maximum speed restriction of 120km/h.
The tread pattern on truck tires:
In commercial trucks, there are three basic tread patterns: longitudinal, transverse, trailer type, and compound type. Each tread pattern has its features, benefits, and drawbacks. In a nutshell, the transverse pattern’s main purpose is to reduce friction. The longitudinal design improves lateral skid resistance and tyre guiding. On the other hand, the compound pattern is well-suited to the functions of the two patterns.
Retreading of tyres:
Tyre retreading is a technique that gives your old, worn-out tyres a new lease on life. This procedure entails replacing the tread and rubber’s structural quality. Several producers of tyres in Liverpool, particularly those affiliated with commercial trucks, have used cutting-edge technology to develop retreaded tyres over the years.
Compared to the other parts of a vehicle, a tyre is one of the most important components that can withstand the most wear and strain. As a result, tyre insurance is just as important as other elements of a car.
Knowing a few fundamentals about the truck tyres in Liverpool will make the selection process go more smoothly. In a word, understanding your truck’s tyres is a must-have skill for today’s fleet managers and for one who requires a truck tyre.
