Ever attempted to buy a car tire and been barraged with the realization that you could just clothe your rims with any kind of rubber? You might even be asking he big question that ‘What do the numbers mean on a tire?’ Well welcome to the world of most drivers. Fortunately, science and a great many engineers have crafted different car wheels to suit the different automobiles and be prepared for various uses. A good understanding of car rueda, how to fix one, what the numbers on the side of the tires mean, or how to measure tire size is necessary for the average driver to have a good command over his vehicle. Understanding your vehicle always makes for a better car owner. Fortunately or unfortunately, most people have not had their tire size explained, causing a lot of havoc and stress when they have to get car rubbers for themselves. Hopefully this article will bring you out of the dark about what your size is. This would definitely put you on the map as a slightly more elite driver than most.

The Meaning Of Car rubber Specifications

Certain specifications details ensure the safety of the wheel being used. Things like size, it’s geometry and it’s type it is tells a lot about what it will be able to do. Usually, the specifications are dictated by the Tire and Rim Association and the European Tyre and Rim Technical Organisation, giving more insight into the tire measurement meaning. People always ask ‘What does tire size mean?’ The answer to the question on tire size meaning is, this is the optimum size that it should be able to operate. It includes the aspect ratio, the width and its diameter. Those who have bought this rubber on rims can sometimes be wondering, ‘What do tire size numbers mean?’ or ‘What does the first number in tire size mean’. On the side of the rubber are a bunch of numbers and letters each telling of what exactly the specification of the rubber i is.

Rubber Size Broken Down

A good example would be this string of numbers and letters: P 185/ 60 R14 82H Some people wonder to themselves ‘What do the first numbers in the tire size mean?’ First off, the first letters states the type. It tells of the standard with which it was made, to suit the particular vehicles. There are other letters which may be used. P: The rueda is for passenger vehicles LT: This means for light trucks. The best suitable ones for up to 1 ton of load capacity on a car. T: Temporary -for use in care of a flat rueda. ST: This specification is for trailer cars. No letter means it is Euro-metric and it simply has a higher load capacity than the regular ‘P’ ones. Next is the number 185 which simply tells of the wheel width in millimeters This is a measurement of the distance between the two sidewalls. For the question ‘What does the second number in tire size mean?’ Here is the answer: number 60 talks about the aspect ratio of the wheel, and it gives an idea of the height of the wheel with respect to the width. 60 means that the height of the wheel is 60% of its width. The rubber is likely to react to several textures on the road. Larger and heavier automobiles have a bigger aspect ratio. R: It stands for the type of construction of the rubber around the rim. R means radial. Another option would be B which means Bias. Radial types boast of a great grip on the road because it’s carcass are fixed around the axis in a radial fashion. This even allows them to wear out more evenly. This is not so much the case of the B type. They have more diagonally placed cable plies, resulting in less grip on the road. For those wondering about the measurement meaning, the diameter is the next number after the construction. It is measured in inches. This is necessary to determine your best replacement in case you need to change the wheel. The number 82 in this case stands for the highest weight of load that the rubber can hold up. They usually vary from 70-126 and increase based on the increase in load it can carry. LT types have two load indices. This is dependent on whether the wheels have been paired or not. The first number would denote a single wheel and the second load index would be telling of the weight it could carry if the wheels were paired especially at the back. The final letter H stands for the speed index of the car. This is the highest speed the rubber can take. H – 210km/h Z- no maximum speed and is designed for sports automobiles especially. Next time you are looking to buy a set, hopefully the letters on the side of the rubber would make far more sense to you than it did before, and then you would be able to buy the best one for your automobile.
