- Excellent traction, self-cleaning and driving comfort
- Long tyre life and uniform tread wear
Reduced soil compaction
Firestone re-engineered tyre-casing with better flexing-properties result in a bigger footprint, reducing the pressure in the contact-area with the soil. Low soil-compaction results in more and bigger crops and yield, directly contributing to more profit.
Improved fuel economy
Superior traction achieved through excellent self-cleaning of the lug-pattern allows you to cover more ground faster, saving you time and fuel.
Save time in the field
Firestone agricultural products are developed to make farming more efficient. Excellent traction and self-cleaning in combination with the possibility to carry heavier implements or more load result in a significant gain of time. The interesting D/E-speed rated tyres allow you to drive on the road at high speeds, contributing to even more time-savings.
Outstanding road handling and comfort
Due to optimised lug- and tread designs, Firestone tyres produce maximum traction in the field and better handling on the road. You can be sure of very accurate steering- and braking response. Renewed tyre-carcasses offer improved damping-characteristics, contributing to a more comfortable drive without vibrations and road noise. We care about your well-being.
Long and reliable wear
Optimised compounds and a unique tyre-construction in function to the task to be performed make Firestone tyres extremely durable so they last longer. Flatter and wider threads in combination with an optimised lug design lead to even pressure distribution on the road, resulting in a uniform wear and extended tyre-life. Firestone products keep on performing, even when half-worn out.
Tyre Development Features
Increased load capacity
Strong and well engineered tyre-casings make it possible to deal with the heaviest loads without compromising your operation-speed. This product is developed to fulfill the high load requirements of special farming-applications.
Dual Angle Lug
Firestone's unique Dual Angle Lug technology, as applied in the majority of our products features a special lug design with a distinctive ridge in the lugs. The special lug design increases traction tremendously while keeping soil-disturbance at an acceptable low level. Firestone products with Dual Angle lugs deliver 4% more traction than standard tyres. The lug-design features excellent self-cleaning, further increasing the traction properties.
Good self-cleaning of the tyre-pattern improves traction and reduces tyre-slip. Firestone's unique Dual Angle Lug technology contributes to better self-cleaning of the lug-pattern. Mud does not cling between the lugs, further improving the traction-properties, saving your time, fuel and top-soil.
High Speed Index
A large number of our tyre-patterns features D/E rated speed-indexes, allowing you to transport heavy loads at high speeds, up to 70 Km/h. Re-engineered tyre-casing with better damping characteristics result in high-speed operation with optimum driving-comfort.

Load and Pressure Table
|Speed (km/h)||Max. Load per Tyre (KG) - Pressure per Tyre (bar)|
|(*):||Cyclic Application (see note)|
|Note:||* Cyclic tyre bonus loads are permitted for traction wheels in cyclic loading operations involving minimal torque and wide fluctuation in weight carried.
* Vehicles must be unloaded before transport outside the field.
* Maximum load may not be carried for more than 1.5 km before unloading operation begins.
* Maximum load per tyre includes all possible field and vehicle/usage variations.
* For hillside operations over 11° (20%) slope, no cyclic bonus load is allowed.
* Basic inflation pressure must be increased as per tables.
