Application Type
Underground Coal Mine – Southeast US

Machine Type
Shuttle Car

Tire Size & Type
14.00-20 Bias Tire

Site Conditions
Harsh underground mining condition with rough floors, steep grades, big ribs and wet conditions.

Tire Problem
Tires are up to 25% overloaded. Tires with polyurethane would start to break down and spin on the wheel, especially when on the grades. This would result in tires usually being changed with 50% tread remaining. Tires would also rib prematurely, destroying the tire and polyurethane fill.

Trojan Solution
Installed Trojan HD Soft Core in the bias tire

Success / Outcome
In most cases, the mine is now wearing out their tires. Trojan has increased the mines tire life by as much as 300-400%. Trojan has also eliminated spinning on wheels. Also, when they do rib a tire, the mine is now able to reuse the Trojan Soft Core – saving huge money!
