I recently bought an ITB Scirocco with 13"x6" wheels (only 4). I have found that they are difficult to come by. I have been running 14" Hoosiers since the 14" wheels are easily accessible; but I have been told that the 13's will be faster.

Does anyone know where to find some reasonable 13x6?

Also --
Recommendation for tires would be appreciated.

Any insight would be appreciated
