Longacre Racing Products Tire Marking Crayon

Longacre Racing Products Tire Marking Crayons: Precision Starts at the Tire

When every lap counts, the details that seem small — like knowing which tires you ran, at what pressure, and under what conditions — can make a real difference in your setup decisions. That's where Longacre Racing Products brings the same philosophy of trackside precision it's applied to scales, gauges, and alignment tools all the way down to tire marking. Tire marking crayons and pens are a staple in any serious racer's pit box, and Longacre's version is purpose-built to meet the demands of competitive motorsports environments.

Why Tire Marking Matters on Race Day

Tires are one of the most expensive and data-rich consumables in racing. Keeping track of which tire came off which corner, how many heat cycles it has seen, what cold and hot pressures were recorded, and what size or compound it is — all of this information lives on the sidewall if you mark it correctly. Without a reliable marking tool, that data disappears the moment tires are swapped off the car and stacked in the trailer.

For oval racers, tire stagger management is critical. Marking tire circumference measurements and stagger readings directly on the sidewall allows crew chiefs and drivers to quickly sort tires during a race weekend without relying on memory or paperwork alone. The same principle applies to road racers and drag racers tracking heat cycles and compound rotation.

What Sets Longacre's Tire Marking Pen Apart

Finer line for easier readability: Longacre engineered their tire marking pen to produce a finer line than a traditional thick crayon, making written numbers and notations much easier to read quickly in a busy pit environment.

• Heat-resistant silver ink: The silver marking formula is specifically designed to stay on the tire sidewall even when exposed to the heat generated during racing — a common failure point for standard markers or crayons that can smear or fade under thermal stress.
• Versatile pit-box utility: Beyond tire identification, the pen is equally useful for logging tire pressures, compound types, sizes, and condition notes directly on the sidewall for quick reference between sessions.
• Trusted across racing disciplines: Whether you're competing in stock car, modified, drag, sprint car, go-kart, or off-road racing, Longacre's tire marking solution fits the workflow of any pit crew that values organization and data.
