ARTISTRO 5 Marcadores de Tinta Permanente à Base de Óleo - Ponta Média para Pneus, Madeira, Pedra, Tecido, Vidro, Cerâmica, Metal, Plástico e Mais -

I’ve used these on three different surfaces already—metal, glass, and a rubber tire—and the ink stays put after drying without any cracking. The fine tip never clogged once, even after I left the cap off for a few minutes.

The medium tip glides over rubber without any skipping, which made my tire lettering look almost factory-done. I've hit them with a pressure washer twice and not a single chip or fade so far. Drying time is genuinely quick, too, so I wasn't stuck waiting around between coats.

I was nervous about painting on my car tires, but these markers glided on smooth and the quick-dry formula meant I didn't smudge a single letter even when I got impatient. The medium tip is perfect for getting clean, precise lines without any bleeding into the rubber grooves.
