SELEAD Jumbo Tire Marker Paint Pens 8-Pack — White, Red, Yellow, Blue | Waterproof, Quick-Dry Oil Ink

If you need bold, durable lettering or bright accents on rubber tires, these jumbo markers deliver saturated color and an adjustable tip for varied line widths. The set includes eight pens loaded with 20 g of professional oil-based ink each, a pump-action feed to maintain steady flow, and a 3-in-1 nib that offers fine, medium and jumbo strokes just by turning the pen. The formula is non-toxic, acid-free and conforms to ASTM D-4236, and it’s engineered to resist washout, UV fading and temperature changes so markings last longer on outdoor applications.

How do these markers handle different tire surfaces and weather?

SELEAD markers are formulated for rubber and other common materials; their oil-based ink adheres well to the textured sidewall of tires and resists rain and car washes once cured. While not a chemical bond like industrial adhesives, the ink provides long-lasting visual results under typical outdoor conditions.

• Waterproof and quick-dry oil-based ink for outdoor durability
• Resistant to UV, temperature and humidity for reduced fading
• Carwash-safe after proper drying
• Works on motorcycle, bicycle, car, truck and ATV tires

What tip sizes can I get from one SELEAD jumbo pen?

Each marker features a 3-in-1 nib that lets you switch line widths from approximately 3 mm to 15 mm simply by changing the way you hold the pen. That makes a single pen useful for fine outlining, medium fills and large, high-visibility lettering or color blocks without swapping tools.

• Fine (about 3 mm) for outlining and small details
• Medium for lettering and mid-size fills
• Jumbo (up to 15 mm) for bold stripes and wide fills
• Durable felt tips designed for consistent, even ink flow

Are these markers safe and easy to use for DIY and professional work?

The ink is non-toxic, acid-free and labeled to ASTM D-4236 standards, making it suitable for hobbyists and professionals who need reliable, odor-moderate paint pens. The upgraded pump-action reservoir helps keep ink separated from air to avoid drying and ensures dependable output without leakage when used correctly.

• Non-toxic, acid-free formulation with ASTM D-4236 conformity
• Pump-action design reduces air exposure and helps consistent flow
• 20 g ink capacity per pen for extended use on projects
• Suitable on tires and many surfaces: metal, wood, fabric, glass, canvas, stone

How should I store and maintain these markers for best results?

To keep tips fresh and maintain reliable flow, always replace the cap after use and store pens horizontally or tip-down for the pump mechanism to stay primed. Avoid leaving the nib exposed to air for long periods and test on scrap material before working on final pieces.

• Recap immediately after use to prevent tip drying
• Store horizontally or tip-down to keep pump primed
• Purge gently on scrap if ink flow slows, then recap
• Allow full drying time before subjecting markings to heavy wear
