I have no dog in this fight. I have my own opinion on the tire companies but I will not bring that out to turn this thread into a pissing match. I do have a question that owners/drivers will be able to answer.

With so many tracks/sanctioning bodies mandating DT-3's as the required RR I was wondering what the cost of these tires have done over the last few years compared to other compounds of tires? Have all tires increased in price the same percentage or have the DT-3's gone up more since it is the only tire most places run?
