The problem with onroad racing isn't foam tires and rubber tires being the end all be all. The problem is people feeling they have to come up with a new class every time someone whines. There are plenty of classes for someone new to get into. But when you go to an event and they have 4 tc classes and the only difference is motor size all you do is limit the field in each class. Then the new guy has to decide what they feel will be the biggest of the classes in the near future.
If people are complaining about having to buy a truer for foam tires why don't the companies offer tires trued. JFt does that with there spec tires and it works great for people without a truer.
I'm all for progress and adapting but the question is about 1/12 and rubber tires. If you don't like foam tires don't run 1/12. I don't like rubber tires so I choose not to run those classes. But I'm not goin around trying to change a class to suit my desires.
