Maintenance Reserves: Planning for Tires, Brakes, and the Unexpected

A truck that runs 2,500 miles a week wears parts. Smart owners set the money aside before they need it.

Maintenance is the line item that catches new truck owners off guard. The first six months are usually quiet — new tires, fresh brakes, recent service. Then, somewhere around the one-year mark, the bills arrive. Smart owners plan for that cycle from day one.

Typical hot-shot maintenance intervals

• Oil and filter service every 5,000–7,500 miles.
• Tire rotation and inspection every 5,000–8,000 miles.
• New steer tires every 60,000–80,000 miles; drives may last longer.
• Brake service every 80,000–150,000 miles depending on lane terrain.
• DOT annual inspection — required.

Why a reserve, not a credit card

Maintenance is predictable in aggregate even when it's unpredictable in timing. Setting aside a per-mile reserve — collected weekly out of gross revenue — turns a $4,000 tire bill into a non-event. Without a reserve, the same bill becomes a cash crunch that interrupts driver pay or fuel.

How it shows up on a weekly statement

Under the Grand Line model, a small per-mile maintenance reserve is funded each week before net is calculated. When the truck needs tires, brakes, or scheduled service, the reserve pays the bill. When the reserve grows beyond what the truck reasonably needs, the surplus can be distributed. The point is to make the unexpected expected.
