Top Fuel dragsters are powerful machines that require a robust set of tires to match. With 11,000 horsepower, these vehicles can accelerate from 0 to 100 mph in under a second. Such performance demands specialized tires, and Goodyear is the sole manufacturer of these tires, which retail at $917 per tire. Given the extreme forces exerted on the tires, they are only expected to last for eight runs or approximately 1.5 miles. This raises the question: is the performance advantage worth the high cost and limited durability of these tires?
| Characteristics | Values |

| Cost of a single tire | $917 |
| Tire lifespan | 8 runs or 1.5 miles |
| Tire manufacturer | Goodyear |
| Tire size | 36 inches tall, 17.5 inches wide, 48 pounds |

What You'll Learn
Goodyear Tire manufactures Top Fuel dragster tires
Top Fuel dragsters are some of the most powerful vehicles in the world, and they require specialised tyres to match. Goodyear Tire is one of the largest tyre manufacturers in the world, and they produce tyres for these dragsters.
Goodyear Tire manufactures the Eagle Drag Slick, a proven winner in many NHRA Drag Racing classes. The Eagle Drag Slick is available in two varieties: a drag slick and a DOT Drag Radial. The Eagle Drag Slick is designed to provide the traction necessary for dragsters to accelerate in a straight line.
Goodyear also manufactures the Frontrunner Dragster Tires, which are identical to the tyres used by pro nitro teams. These tyres are offered in two width sizes and can be used on a variety of dragsters, including Top Fuel, A/Fuel, and blown alcohol dragsters.
Goodyear has a long history in tyre manufacturing, dating back to its first factory in Akron, Ohio, in 1898. The company has since grown into one of the largest tyre makers in the world, supplying tyres for a range of vehicles, from bicycles to Top Fuel dragsters.
The Goodyear Top Fuel dragster tyres are 36 inches tall, 17.5 inches wide, and weigh 48 pounds each. They cost around $917 per tyre and are expected to last for eight runs or approximately 1.5 miles.

Each tire costs $917
These tires are put under immense stress and force, and it's fascinating to see how they work. When the car launches, the tires expand to up to 38 inches in diameter, and the contact patch lengthens and narrows. This adjustment in the tire's shape lets the final-drive ratio grow taller, allowing for higher speeds and reduced rolling resistance.
The tires are so important that they are often the focus of racing engineers, who study how to get the best performance out of them. For example, before a race, the tires are heated up during a burnout to prepare them for the full-power run.
Despite the high cost of $917 per tire, these tires are not expected to last very long. Each tire is predicted to endure only eight runs or a little more than 1.5 miles before needing to be replaced.

Tires last 1.5 miles
Top Fuel drag tires are expected to last only 1.5 miles. These tires are priced at $917 each, and they are manufactured in Akron, Ohio. They are 36 inches tall, 17.5 inches wide, and weigh 48 pounds apiece. They are an essential component of a dragster, converting 11,000 horsepower into a 3.7-second, 335-mph run.
The lifespan of these tires is a mere 1.5 miles due to the intense forces and stress they endure during a drag race. The tires spin at incredible speeds, generating a friction coefficient above 1. This means that the friction between the tires and the track is extremely high, resulting in rapid wear and tear. Additionally, the tires undergo significant distortion during the race, with sidewalls wrinkling and the tread balling up, further contributing to their limited lifespan.
The compression of the tires during the race is a critical factor in their performance. As the tires compress, the contact patch expands to almost 250 square inches, providing a larger surface area for traction. This compression also shortens the final drive ratio, resulting in a harder launch and more acceleration. However, this compression comes at a cost, as it contributes to the rapid wear and tear of the tires, limiting their lifespan to just a few runs or 1.5 miles.
After a race, the rear tires may develop flat spots and distortions, rendering them unusable for future races. These used tires are often repurposed for slower classes or turned into "draggers," which are used to coat the track with rubber to improve grip for other vehicles.
The technology behind these tires is impressive, but the cost and limited lifespan of just 1.5 miles highlight the intense nature of drag racing and the demands it places on the equipment.

Tires are 36 inches tall
Top Fuel drag tires are an essential component of dragsters, and their performance directly impacts the vehicle's acceleration and speed. These tires are specifically engineered to handle the extreme forces and conditions of drag racing.
The tires used in Top Fuel drag racing are massive, measuring 36 inches tall and 17.5 inches wide, and weighing in at 48 pounds each. Their sheer size contributes to their impressive performance capabilities. These tires are so powerful that they can propel a dragster to speeds of over 335 mph in just 3.7 seconds over a 1000-foot run.
The cost of these tires is significant, with each one priced at around $917. However, their lifespan is relatively short, as they are designed to last for only eight runs or approximately 1.5 miles. This means that the tires need to be replaced frequently, adding to the overall expense of drag racing.
The process of using these tires in a drag race is fascinating. Before the race, the tires are heated up during a burnout to prepare the rubber for the full-power run. Once the race begins, the tires experience extreme forces, with the sidewalls wrinkling and the tread balling up, causing the contact patch to expand to around 250 square inches. This increased contact area provides the necessary traction to propel the dragster forward with incredible acceleration.
The massive torque generated by Top Fuel dragsters allows them to effectively use and abuse these huge rear tires. The tires play a critical role in the performance of the vehicle, and their unique characteristics contribute to the thrill and excitement of drag racing.

Rear tires distort and develop flat spots
Top Fuel dragster tires cost around $917 per tire, with each tire weighing 48 pounds and expected to last only eight runs or about 1.5 miles. These tires are an integral part of the vehicle's drivetrain, converting 11,000 horsepower into a 3.7-second, 335-mph run. This extreme performance comes at a cost, with the tires experiencing significant distortion and abuse.
The rear tires of these powerful vehicles are subjected to intense forces, especially during deceleration. As the car slows down, the rear tires distort and can develop flat spots at their trailing edges. This distortion occurs due to the massive torque applied to the tires, which exceeds the friction coefficient, resulting in a unique phenomenon where the friction coefficient raises above 1. This distortion is so significant that it can be observed in slow-motion footage, showcasing the abuse the tires endure during braking.
The process by which these tires function is often described as "black magic." Technically, different parts of the tread move at varying speeds, causing the leading edge to bunch up, or "squat." This change in momentum creates a force that acts along the ground contact angle, significantly increasing the downward load on the tires. This vertical force enables the conversion of torque into remarkable acceleration rather than wasteful burnout.
Additionally, the sidewalls of the tires wrinkle as the tire compresses, shrinking in radius by over six inches. This compression expands the contact patch to approximately 250 square inches, which is larger than two side-by-side sheets of 8.5-by-11-inch paper. This expanded contact patch contributes to a more effective launch by shortening the final drive ratio. By the time the tire releases the stored torque, the vehicle is already experiencing high acceleration forces.
After the initial launch, the tire's inertia causes it to expand in diameter, reaching up to 38 inches. This expansion simultaneously lengthens and narrows the contact patch, allowing for higher speeds and reduced rolling resistance as the vehicle approaches terminal velocity. The abuse that these tires endure is evident, and it's a testament to tire technology that they can withstand such extreme conditions.
