When new tires leave the factory, they are coated in a blue protective film to protect the white lettering and white walls during shipping storage. Most tires shops remove this from the tires before fitting them to your vehicle. An interview with Ron Parish, an automotive technician with Gwynn Tire Service in Fairmont, West Virginia, reveals that you can remove the blue coloring yourself with a little work.
Fill a spray bottle with a 50/50 mixture of bleach and water. Shake the bottle to mix the ingredients.
Park your car in a shaded area. Spray the white areas of your tires and use scrub away the blue film with a scrub brush Only work on one tire at a time, to prevent the bleach from drying on the tires.
Hose down the tire to wash away the bleach and all remaining streaks of blue film.
Scrub all remaining tires using the procedure in Steps 1 and 2.
