I think we should look at the question as this.
What constitues a Street Tyre.
I reckon a street tyre is your normal everyday road tyre, not a semi-comp tyre.
I understand that some people drive around with semi-comps on all the time, but I think that's the exception to the rule.
But at the end of the day, its a traction thing, and you can go and buy pineapples and special dampers to set you up for launch, so why are tyres any different.
Also, if you want to be competitive, you will just have to go buy a set if you want to win.
Two schools of thought I guess.
