Hey, I am getting the bike all set up for race season this year and have decided to slap some tires on that are a little better for drag racing. I still ride on the street a decent amount, not really agressive but as often as I can. I know a drag tire will wear much faster the more it is used on the street. Does anyone have any recomendations on which tires to go with? I like Shinkos because they are cheap, and seem to still be round enough to ride on the street and I have seen their performance at the track. The second question is I have an 06 10r with a rear tire size of 190/55. This seems to be a wierd size, I know that Shinko makes a 190/50 and a 200/55. What options do I have as far as sizes that will fit on the rim I have. Do I have to do the exact same size or will others work? Thanks for all the feedback!
