I know my opinion probably won't be popular, but that never stopped me before, so here goes... My impression is that tire rules are for promoters and series who want a kickback in their own back pocket. If ART's are truly better, then teams will choose them. If Hoosiers are better, then teams will choose them. Tires are something that the teams should choose, not the sanctioning body or the track. Teams want to go fast and they want to win. Teams will choose what is best for them to meet their goal of winning. If teams were getting a highly-discounted group rate, it would be one thing. I don't know of any series with a mandated tire rule that offered significant discounts, mostly because the tire manufacturer doesn't have any competition. Usually the opposite is true. Nice gig if you can get it!

It's interesting to note that the new BOSS series wingless sprints does not have a tire rule. I applaud their efforts in this regard.
