Lol.. I guess you guys don't seem to like my sports soft tires idea.
I haven't practiced with them yet, but in a few runs in the online B-spec seasonal, the sports softs work quite well in the wet. They last longer than the intermediates and rain tires as well.
The sports tires have grooves on them that channel the water away. The intermediates have some, but are of a bit softer rubber and wear out faster than the sports softs. The rain tires seem to be racing softs with grooves, they seem to wear out the fastest.
All of this is just my observation with B-spec. I figured it would probably be similar.
As far as which tires should be used for a race car.. I am sure the race teams would use whatever they were allowed that gave them the best performance. If it were sports softs, I'm sure they would have no problem using them if they fit regulations.
But of course I am fine just using the racing hards, intermediates, and rain tires. I just wanted a clarification before practicing.
