Why are F1 Tires Covered?


F1 wheel covers have been a hot topic of discussion in the racing community for many years. The covers, which can also be referred to as wheel socks or wheel blankets, are mandatory in Formula 1 racing. But why are they necessary? In this article, we will look at the purpose of F1 wheel covers in terms of safety, aerodynamics, and branding.

Definition of F1

Formula One (F1) is the highest and most prestigious class of single-seater auto racing sanctioned by the International Automobile Federation. It is considered the Formula One World Championship, essentially a competition of speed and engineering between automobile manufacturers. The goal of F1 is to create a car capable of achieving maximum speed while being lightweight and agile enough to corner at high speeds. The cars are pushed to their performance limits to gain an advantage over their competitors in worldwide races.

The cars feature advanced aerodynamics, sophisticated suspension and braking systems, and robust engines and tires. The tires are typically covered with tire warmers during pre-race preparation on race days to increase their grip levels when negotiating turns at extreme speeds.


Wheel covers have been used in Formula One since the early 1990s when the regulations required them to be fitted to all cars. Initially, they were used to protect the tyres from dirt and debris, but they have since become integral to a team’s aerodynamic package. In this article, we will explore the history and evolution of wheel covers in Formula One and look at how they are used today.

Evolution of F1 tires

Formula One racing is a high-stakes sport that calls for the best in technology and safety measures. Most of us define what we know about F1 tires by their round, black, exposed shape; however, tire designs have changed to give drivers improved safety features over the years. The essential part of modern F1 tires is why they are covered during Formula One races: to allow heat to escape without causing cross winds that could upheave a car in motion.

In 1967, Firestone developed a tire covering and tested it in practice runs with Mario Andretti at the wheel. The idea behind these new covers was sound – they created a bulb effect that allowed the heat generated away from the brake rotor to dissipate through metal mesh fabric before it had an opportunity to cause any disruption or upset when passing other cars. Firestone’s engineers included perforations on either side of the material to ensure maximum airflow and cooling efficiency.

This was revolutionary then as it is today, providing a higher degree of race safety for competitors and spectators alike due to its reduced risk of on-track fire and blowouts. All Formula One teams use similar covers made from Firestone’s Mesh Fabric material today. Still, many creative designs have been seen since Formula One rules allowed plastic frame covers in 2003.

Since then, teams have adapted this design with aerodynamic shapes and modifications that go beyond just reducing turbulence; some elevate Function >From Design (FFD) capabilities – such as storing tools or camera crew – all while keeping F1 tires safely covered during racing events all around the world.

Design and Materials

Formula 1 cars are built for speed and performance. The tires used to deliver these high speeds are also an essential factor. The tires are covered with wheel covers to protect them from the elements. Much more design and material science go into wheel covers than meets the eye. Let’s take a closer look.

Tire construction

Formula One cars are designed for peak performance on the circuit, which places high demands on the tires. These tires must provide grip, stability, and comfort to allow drivers to get the most out of their car while navigating tight turns and high speeds.

Tires are constructed using a variety of different materials that serve specific purposes. First, a synthetic rubber layer is applied around an inner core — also known as a “carcass”—made of steel cords wrapped in a fabric such as nylon or polyester. This helps maintain the tire’s shape while driving over bumps and allows it to absorb shocks.

On top of this core sits multiple layers of reinforcing rubber compounds called slicks, which vary in composition, construction, and thickness depending on location — thicker compounds are used in the middle for traction, with thinner ones near the edges for feedback to the driver. To protect these layers from abrasion, F1 tires are usually covered in protective canvas or Kevlar sleeves, ensuring that each tire is ready for every race.

Wheel covers

In modern Formula 1 racing, teams use wheel covers to streamline airflow around the car. Wheel covers, also known as aero covers or fairings, are made from carbon fiber composite material which is both lightweight and strength-efficient. They also provide additional downforce to the wheels when attached, which translates into a better grip on the track.

In terms of aesthetic appeal, these wheel covers add a race-inspired look when naturally exposed but can be camouflaged to match the base color of their respective designs. Beyond looks, however, their primary purpose lies in improving aerodynamics by ensuring that air moves more uniformly around the car rather than over it – this reduces drag and allows for speeds that would otherwise not be achievable without them.

The construction of F1 wheel covers is rigid and complex; an intricate web of layers encases a single-point hub with surprisingly few air holes for what you’d expect given their low drag profile. Generally speaking, all parts must be designed to integrate perfectly with each other as there’s no space for bulky gaps and folds between panels, an example being their near flushness against the truck floor- it needs to be perfect, or else there will be vast amounts of drag and probably an even more enormous repair bill at the end of each race!

Benefits of Wheel Covers

F1 wheel covers are essential components used by Formula 1 teams around the world. They provide numerous benefits, including the protection of wheel rims, aerodynamic aid, and the ability to help cars maintain grip during wet or hot conditions. Let’s take a closer look at all the advantages wheel covers can provide for drivers.


One of the primary reasons to cover the tires on Formula One race cars is to create better aerodynamics. Increased wind resistance can significantly impact when a vehicle takes turns at high speeds or reaches very high speeds over long distances. High-performance vehicles such as those used in Formula One racing require special design considerations for efficient airflow.

Wheel covers reduce friction and drag due to their ability to smooth out the surface of the tires and deflect air away from them. This helps keep air pressure affecting the vehicle’s wing elements consistent and can significantly change lap times. Wheel covers also reduce weight from the car because they’re lighter than standard rims, which is essential for higher speeds and performance.

Covers are also designed with cooling properties in mind; they provide an efficient way to dissipate heat away from essential components while simultaneously improving aerodynamics around them. On a hot day at very high speeds, this is important for avoiding structural damage and controlling critical temperatures within various parts of the car’s engine internals.


From a safety perspective, wheel covers improve the reliability of Formula One cars by reducing wheel turbulence, which can result in better aerodynamics. This helps provide more stability at high speeds, minimizing the risk of spinning out of control or crashing. Additionally, the covers protect drivers from debris thrown from the tires and potentially cause injury to them or those around them. In addition to providing a layer of protection for drivers, wheel covers also help extend the life of tires by shielding them from dirt and grime. This helps ensure that tires have a consistent grip on the track, improving overall driving performance.


To summarize, F1 tires must be covered for several reasons. Due to their high cost and limited availability, covering them helps minimize the potential of damage or theft before they reach the track. The extended life of an F1 tire will also help keep costs low, allowing teams to spend less on new tires and more on other aspects of their race cars. Finally, with the wide range of conditions they face at each track, coverings help protect F1 tires from dirt, dust, heat, and other environmental factors that could reduce their performance or lifespan.
