Read our article and find out all about the weight of your tyre. Which parts of the structure weigh the most? Are heavier models better? What does tyre weight and performance have in common and how important is this parameter? What are the dilemmas faced by tyre manufacturers?

Weight is one of the most important parameters of any tyre. How much does the tyre weigh is the result of the designers' choice and internal construction solutions applied. All factories are obliged to respect the previously assumed weight. This is particularly important when a given size is produced in different factories.

Will lighter tyres be the best, or vice versa?

Tyre weight

A lower tyre weight enables a multitude of factors. The most important of which include a reduction in the rolling resistance, enabling a lower fuel consumption rate for the vehicle itself.

It also similarly offers a decreased unsprung weight. This results in better performance for vehicles when braking, acceleration or undergoing precision steering maneuvers. It also helps to offer better driving comfort and lower wear and tear on the car’s suspension elements.

Because of these benefits, most manufacturers aim to reduce the weight of their tyres with every successive generation. This leads to better performance parameters for the product, as well as lower costs of production and materials for the manufacturer. However, this situation can often be different when producing high-performance tyres, as weight is a particularly important parameter. Here, companies often use advanced technologies and materials which may cause the tyre to be more expensive, even if it is still lighter.

Methods Used To Reduce The Tyre Weight

The development of the tyre world is clearly moving towards a gradual reduction in the overall weight of products. Why is this and what do drivers gain from it?

  • Weight also reduces rolling resistance, reducing average fuel consumption and environmental impact.

  • Lowering the unsprung mass ensures better performance in the range of :  breaking, acceleration, steering precision, driving comfort, longer suspension lifespan.

Most manufacturers choose to reduce the weight of their tyres with each new generation. This translates not only into higher performance, but also into lower production and material costs. The situation may be slightly different for off-road tyres, where the weight is still an important parameter. These models may feature different technologies and materials.

Methods used to reduce the weight of tyres:

  • the so-called. slimming of  tyres, i.e. reducing the weight of individual components (tapered banding, tread, tyre front, etc.).

  • the use of lighter construction concepts, appearing in line with technological development.

  • use of lighter weight materials (e.g. steel or textile cords made of lightweight fibres).

Weight plays an important role in the production process of a tyre, mainly because of the pre-established standards for a particular model. There is, of course, the possibility of small variations within the accepted tolerance. These limits are usually stricter when it comes to approved tyres.

Off-tolerance tyres are treated as non-compliant and do not reach customers. Too little or too much weight in relation to the specified tyre may suggest the absence of certain tyre components, the use of incorrect compounds or the presence of a foreign body, or the lack of stability of the production process.

Tyre tread

The tread has the highest percentage of the weight of the tyre.

How much do exemplary tyres weigh?

The market for passenger car tyres is diverse and the number of sizes available is very large. From 13-inch tyres for small city cars to more than 20-inch models for SUVs and sports cars. Tyres also vary in weight. Here are some examples:

Tyres for sports cars are statistically heavier.

Truck tyre weight

Truck tyres are much heavier than passenger car tyres. The weight of a truck tyre can range from 30 kg to as much as 80 kg. It all depends on the diameter, as 24-inch wheels are usually the heaviest.

How much does a 17-inch tyre weigh? Approximately 35 kg. For another popular size (22.5 inches) it is 60 kg.

Differences in tyre weight

Significant differences in the mass of individual sizes result from the application of different solutions within a single model. After all, some tyres have to offer different performance for several types of cars, as well as withstand different speed and load ranges. Sometimes, within the same model and size, tyres have even higher speed and load ratings.

For example, extra load tyres (XL) will be heavier than the standard size. This is because they are equipped with additional components that strengthen their construction and provide a more massive structure.

Share of tyre components in the tyre mass

We've already found out how many kilograms the total weight of the tyres in each size can reach. Let's see how much each component weighs. Each radial tyre currently produced for passenger cars must consist of elements such as: wire with filler, butyl cap, textile cord layer (warp), side with an alloy belt, tread, headbands (steel bands and very often a screen with a zero degree belt).

Tyre construction.

How Different Elements Contribute To Tyre Weight

Depending on the intended use of the tyre, its speed and load indexes, the manufacturer's construction concept and production process, various elements can be added to the structure. However, it should be remembered that their share in the total weight is usually lower than the basic components and does not exceed a few percent of the total weight.

In the case of the basic elements, the largest share is represented by the tread, the weight of which accounts for approximately 35% of the total weight of the tyre. For example, a 205/55 R16 tyre can weigh 2.8-3.2 kg. The tread weight of 13-inch tyres oscillates around 2 kg. For low-profile models with low sidewalls but significant circumference and wide forehead, the proportion of tread weight is greater and can exceed 40% of the weight of the car tyre. Tread is the only component that changes in weight during tyre use. It wears naturally, and the gradual wear of the top layer reduces its weight relative to its initial weight.
