front tires are 175/80-14 at the moment, cheap street tires. You ask because the "dont mix radials and bias ply" thing? I think this is not a problem if you use these tires track only.
Guys, thanks so far for the good information! I learned the majority prefers real slicks, seems that the Drag radials don´t bite as good.
And i learned the DOT Cheater Slicks are still bias ply / wrinkle wall tires as a drag slick, maybe another compound.
Now i´m waiting for some offers, then i´ll make a decision.
