Currently, kumho, and hankook has dual ownership of sponsoring F1. F1 has history of choosing Asian tire companies due to their superior quality data, and the relationship they have with them. the article about Pirelli having contact term with F1 is a media play all around. you do the tech analysis every weekend? lol the nascar race does not run every weekend u idiot. have you ever been to a F1 racing events? jeff Gordon would laugh at you saying, the relationship between F1 and the tire companies. the size of tires does not matter when choosing the tire company from F1. it is all about the relationship, and the back hand deal that goes on, it is beyond political measure that you can’t even imagine what happens. personally, I for myself have been involved in these dealings because I work for the greatest tire company in the world called the hankook tire.
