The abbreviation used in the index of the commercial tyre Barum BU51 (Barum Universal) indicates its belonging to the brand's line of universal models, which are entirely designed for trucks operating in mixed conditions, both on roads and on pre-compacted gravel surfaces. It stands out for its combination of high load-carrying capacity, resistance to damage, and increased tread life.
Combined tread pattern design
The tread pattern features closed shoulder zones, each consisting of a massive continuous longitudinal rib. These elements enhance directional stability when driving with a full load and improve handling accuracy, while also reducing rolling resistance and wear. The central part, on the other hand, consists of massive blocks with edges that maintain their effectiveness on gravel surfaces.
Reliability under high load conditions
The reinforced carcass design is borrowed from quarry tyres. The multi-layer cord uses a steel wire with an increased cross-section, allowing the tyre to withstand operation in conditions of constant impact and dynamic loads characteristic of construction equipment. In combination with the combined tread pattern design, this makes the tyre a practical solution for dump trucks and specialized trucks that operate without a clear separation of road conditions.
Durability as a factor of economy
The robust and deformation-resistant carcass, combined with the practically flat profile of the tread, promotes slower and more even wear, increasing the efficiency of the rubber compound. Its composition is also largely taken from the brand's quarry tyres, giving the model the ability to effectively withstand cuts, punctures, and cracking.
Key features of the Barum BU51:
- The combined tread pattern supports stable traction on both asphalt and gravel;
- The reinforced carcass from quarry tyres is designed for intensive operation of dump trucks and other construction equipment in difficult road conditions;
- The thickened sidewalls increase the reliability and efficiency of the tyre's operation on technological roads with gravel surfaces;
- The combination of the profile, tread pattern, and specialized compound increases the tyre's service life, reducing operating costs.
