TRI-S tankers are available in capacities from 4000 to 5000 gallons (18,184 to 22,500 litres) TRI-S tankers use three large commercial high speed axles to carry the weight. To aid manoeuvrability with the TRI-S range, both the front and the rear axle provide passive steering as standard. A large Jurop 11000 litre pump is fitted as standard for powerful filling.

TRI-S tankers have a large barrel diameter to keep the overall length as short as possible. A sprung drawbar, a complete folded chassis, tridem commercial axle with front and rear steering along with six flotation tyres provides a high end specification as standard.

TRI-S tankers have a large carrying capacity, and this capacity is distributed over three axles and six tyres. TRI-S have front and rear steering as standard and tyre choice will help to travel over land. Fitted as standard with 600/50-22.5 BKT flotation tyres allows the tanker to float over the ground without damage. The special thread design allows for carrying very high loads at low pressure, guaranteeing at the same time reduced soil compaction and preventing damage to soil. For more roadwork we can recommend 600/50 R22.5 BKT FL693M Ridemax tyres.
