I used to own the machinery to put any type whitewall or stripe on any tire.....grinding wheel rotated around the tire making a cut in the sidewall to any width, then the material is pressed into the cut and put in a heated press, then ground flush with a finish grinder....kinda cool but time consuming and a PITA....but they came out awesome....did a ton of them back in the day. Picked up the equipment from a tire shop that went out of business.
Some companies are still doing it today 8)
