Dunlop Adds to Mixed Service Truck Tyre Range

Peterborough’s TruckFest show – an event co-sponsored by Dunlop Tyres UK – was chosen as the launch venue for new additions to two of the tyremaker’s new product lines. The SP382 and SP482 tyre ranges, designed specifically for vehicles operating in on and off-road conditions, have both received new additions.

The SP482 range has welcomed the introduction of tyre that Dunlop claims now ensures all popular sizes are catered for, a 12R22.5 drive tyre. This tyre range is most commonly used on tippers, concrete mixers, cranes and other construction plant equipment that operate on-road most of the time but also find employment in locations such as construction sites and quarries. Therefore the tyre offers high road mileage while delivering the necessary off-road traction and resistance to stone cuts.

As a mixed service drive axle tyre SP482 with road performance as its prime objective, the range offers high mileage, carcass durability and retreadability. Its construction and tread design ensure a balance of on and off-road traction with the added benefit of good self-cleaning. The tread design of the SP482 has deep radial shoulder grooves combined with a centreline rib for enhanced traction and steering precision. The groove geometry minimises stone holding and provides the self-cleaning properties.

The Dunlop SP382 is a mixed service steer tyre that can also be used as an all position tyre if required. The tread is wide and deep and features solid ribs. As stone penetration is a risk factor in the conditions in which this tyre is designed to perform, the tyre’s carcass features a special top belt along with stone protectors to minimise any ill effects. This enhanced carcass integrity in turn improves the tyre’s retreadability. Two designs of the SP382 are available; a 4-rib version for standard aspect ratio sizes and a 5-rib version for low aspect ratio sizes when they become available.

Both ranges feature a top breaker construction known as TPL (Top Protective Layer) technology. This is a corrosion-resistance barrier built into the tyre between the tread and the high-strength steel belts. TPL technology protects against damage due to penetration as well as preventing moisture from causing corrosion damage.
