Firstly, I would like to point you in the direction of the AUP, you agree'd to it when you signed up therefore I feel that you should abide by it. You do not need a capital letter for every new word. Your English seems good enough to me for you to already know this.

Secondly, I'm sure the percentage of comfort tire drifters is a lot higher than 85%. Sport tires have far too much grip to be able to pull off such moves as the Tandem or to even keep a drift stable enough for an extended period of time.
I would also like to add that these kinds of threads are in abundance around this sub-forum so I would like to advise you on searching to find relevant threads rather than creating your own.
Threads about tires create a lot of controversy and are best avoided in this sub-forum.
