The edding 8050 tyre marker was developed to make permanent markings on new or used tyres and other rubber surfaces. This tyre marker comes in handy when changing between winter and summer tyres, when storing large numbers of tyres, touching up whitewall tyres or when restoring writing on motorbike tyres. The edding 8050 tyre marker is both quick drying and waterproof with a lacquer finish. Before using the pen for the first time, shake it briefly, and pump the bullet nib several times on a piece of cardboard after removing the cap until ink flows into the nib– then the tyre marker is ready to go.
