Maybe we should eliminate $5 trophies too so we can drop everyone's entry fees by $.50?
Personally, I race a lot and use a lot of tires for two reasons...1) it's necessary to compete at the top 2) there's a correlation between going faster and consuming more tires. Fortunately for me, I'm able to place high enough to benefit from the contingencies and it absolutely makes a significant difference in my annual spend. In fact, it's one of the factors I consider when contemplating what/where to run. It's also (and maybe primarily, especially in a spec series) an incentive to perform well...for everyone.
Steve - you've made you're point and expressed your opinion. Others, like me and maybe (probably?) those who buy the majority of SM tires, have different opinions.
