When it comes to the biggest wheels in the world, most people think of giant trucks. BelAZ or mining dump trucks Caterpillar. However, the record sizes exceed even these monsters: the diameter of such wheels can reach 4 meters, and weighs several tons. These engineering marvels are not designed for speed or comfort, but to solve highly specialized tasks: transporting ore in quarries, working on construction sites, or even participating in show projects.
In this article we will look not only absolute records (recorded in Guinness Book of Records), but also practical aspects: how such wheels are made, what loads they can withstand and why they cannot be installed on a regular car. You'll also learn little-known facts, such as the fact that some of these giants do not have rubber tires in the usual sense, but are all-metal structures with polyurethane inserts.
Absolute record: the largest car wheel in the world
As of 2026, the official record belongs to wheels mounted on a mining dump truck. BelAZ-75710. Their key parameters:
- 📏 Diameter: 4.03 meters (taller than the average person!)
- ⚖️ Weight of one wheel: 5.5 tons (including tire and wheel)
- 💪 Load capacity per axle: up to 100 tons
- 🔧 Tire pressure: 7.5 bar (3 times higher than in a passenger car)
These wheels are manufactured by Bridgestone by special order. I wonder what one such tire costs about $60,000 - more than some budget cars! At the same time, the tire life is designed for 10,000–12,000 hours of operation in extreme quarry conditions.
For comparison: the wheels of the largest production pickup truck Ford F-650 have a diameter of only 1.2 meters - 3 times smaller! And the pressure in passenger car tires usually does not exceed 2.5 bar.
Technical features of giant wheels
The design of record-breaking wheels is radically different from conventional tires. Here are the key differences:
| Parameter | Regular tire (passenger car) | Giant Tire (Mine Truck) |
|---|---|---|
| Cord material | Steel or polyester | Carbon fiber + Kevlar |
| Tread type | Ribbed or block | Smooth with deep grooves for self-cleaning |
| Installation method | Pneumatic jack | Special crane with a lifting capacity of 20+ tons |
| Temperature | –30°C to +50°C | From –50°C to +120°C (work in deserts and the Arctic) |
One of the most surprising solutions - tubeless design. In regular tires, air is retained by the seal between the tire and rim, but in giant wheels, air is used liquid seal: a special gel is poured between the tire and the disk, which crystallizes when inflated. This avoids depressurization under extreme loads.
If you ever see one of these trucks in a quarry, pay attention to the color of the wheels: yellow stripes on the sidewalls of the tire mean that it is designed for operation in high temperatures (for example, in the deserts of Australia), and blue stripes for arctic quarries.
Where are record wheels used?
Main areas of application:
- ⛏️ Mining industry: dump trucks BelAZ, Caterpillar 797, Komatsu 980E transport ore and coal in quarries. One such wheel can support the weight of 50 cars!
- 🏗️ Construction of dams and bridges: To move concrete blocks weighing up to 200 tons, special platforms on wheels 3 meters high are used.
- 🎪 Show business: in 2023 the company Monster Jam introduced the truck Megalodon with wheels with a diameter of 2.5 meters - for jumping over 20 cars!
- 🚀 Space industry: missile transporters (for example, for SpaceX Starship) are equipped with wheels with a diameter of 2.3 meters with individual electric drive.
Fun fact: in 2021, Chile created world's largest wheeled excavator Bagger 293, in which each of the 12 wheels has a diameter of 3.8 meters. It weighs more than 14,000 tons - more than the Eiffel Tower!
Why aren't these wheels used on regular trucks?
The main reason is incompatibility with road infrastructure. Even if it were possible to adapt the suspension, such wheels would destroy the asphalt in a matter of kilometers due to the enormous pressure on the surface (up to 15 kg/cm²). In addition, their width (up to 1.5 meters) makes it impossible to drive along standard lanes.
How are giant tires made?
The production process of one tire for BelAZ-75710 takes up to 3 weeks and includes 150+ operations. Here are the key steps:
- Frame assembly: On a special machine, cord threads are laid in layers (up to 20 layers of carbon fiber).
- Vulcanization: the workpiece is placed in an autoclave under a pressure of 20 atmospheres at a temperature of 180°C for 24 hours.
- Application of the protector: special rubber with the addition of silicon oxide is used for increased wear resistance.
- Balancing: the wheel is checked on a vibration stand with an accuracy of up to 50 grams (with a weight of 5 tons!).
To transport the finished tire you need separate truck with a manipulator. Interestingly, some manufacturers (for example, Michelin) offer service Michelin Earthmover Management — remote monitoring of tire condition in real time through pressure and temperature sensors.

Records and curiosities: unusual facts about big wheels
World records in this area are often associated with non-standard projects:
- 🎬 Film industry: for the film "Mud Max: Fury Road" wheels with a diameter of 2.1 meters with spikes were created - they weighed 1.2 tons each.
- 🏆 Guinness Book of Records: in 2019 a record was set for longest continuous movement on one wheel - truck Terex Titan drove 1,000 km on a closed track on one 3.5-meter wheel (the rest were dismantled!).
- 💰 Most expensive tire: in 2022, a tire from Liehberr T282B for $120,000 - it was bought by a collector from the UAE.
Here's a fact that will amaze even experienced motorists: some mining dump trucks are equipped with wheels with individual electric drive. For example, in the model Komatsu 980E-4 each of the 6 wheels has its own electric motor with a power of 1,200 hp! This allows for more precise distribution of traction force and reduced tire wear.
The main difference between giant wheels and regular ones is not only the size, but also complete lack of compromise in strength. While a passenger car tire is designed to last 5–7 years of use, a mining tire must withstand extreme loads 24/7 without the risk of explosion or delamination.
Is it possible to install a record wheel on a regular car?
Technically - no, and here's why:
⚠️ Attention: Even if it is physically possible to adapt the mount, the car’s center of gravity will rise so much that the car will tip over at the slightest turn. In addition, the steering and braking systems of a passenger car are not designed to withstand such loads.
However, enthusiasts find workarounds. For example, in 2020, the American customizer Big Mike created a pickup truck Ford F-350 with wheels with a diameter of 2.4 meters (wheels from agricultural machinery and specially made tires were used). To do this we had to:
- Extend the suspension struts by 1.2 meters
- Install additional hydraulic shock absorbers
- Move the steering rack above the hood level
- Use tires with a pressure of only 0.8 bar to reduce the load on the suspension
Result? The maximum speed of such a monster is 40 km/h, and fuel consumption exceeds 100 liters per 100 km. But at the show SEMA this pickup won the prize for "The most extreme project of the year."
The future of giant wheels: what awaits us?
Engineers are already working on new solutions:
- 🔋 Airless tires: Michelin tests the model Tweel for quarry equipment - instead of air, a polyurethane “web” is used, which is not afraid of punctures.
- 🤖 Self-cleaning protectors: Ultrasonic sensors are built into the tires, which vibrate and remove stuck dirt.
- ♻️ Recycling: company Bridgestone has developed a technology for processing used giant tires into fuel for cement kilns (one tire provides energy to produce 5 tons of cement!).
It is expected that by 2030 wheels with a diameter of 5 meters for new models of dump trucks with a carrying capacity of 500+ tons. And in the project NASA for the colonization of the Moon, wheels made of a titanium and aluminum alloy with a diameter of 3 meters are already being considered - for lunar rovers that will transport cargo between bases.
If you ever find yourself near a mining dump truck, pay attention to the sound: when moving, such wheels emit a characteristic low-frequency hum at a frequency of 20-30 Hz, which can be felt more in the body than heard.
FAQ: Frequently asked questions about the largest wheels
How much does one record wheel cost?
The price depends on the model and manufacturer. Tire for BelAZ-75710 costs about $60,000, and for Caterpillar 797F - up to $80,000. At the same time, the disk costs another $15,000–$20,000. Installation cost (using a crane) - from $5,000.
How often are these wheels changed?
In quarries, tires last 12–18 months when used around the clock. The criterion for replacement is not mileage, but tread depth: When it is reduced to 20% of the original, the tire is written off. For comparison: in a passenger car the wear limit is 1.6 mm, but here we are talking about centimeters!
Is it possible to buy a used record tire?
Yes, but it's a difficult process. Companies usually sell scrap tires through auctions (e.g. Ritchie Bros.). The cost of a used tire with a diameter of 3–4 meters is $10,000–$20,000. Buyers are often farm owners (for tractors), construction companies or machinery museums.
What is the maximum pressure this tire can withstand?
The operating pressure in the giant tires is 7–9 bar, but they can withstand short-term increase to 15 bar without destruction. For comparison: a standard passenger car tire bursts at 8–10 bars. Quarries use automatic pumping systems that maintain pressure with an accuracy of ±0.1 bar.
Why aren't such wheels used in the army?
Main reasons - low maneuverability and vulnerability. Military vehicles need tires that can withstand bullet holes and can be quickly repaired in the field. Giant wheels, despite their strength, require specialized equipment for repair. Exception: armored bulldozers Caterpillar D9, but they also use wheels with a diameter of no more than 2 meters.
