My rear tire has a slow leak that i cant find. Its very annoying! I need to replace it asap. I want to replace my current Bridgestone 020's with Pirelli Diablos but cant afford both front and rear right now. I know tires have diffrent profiles for diffrent applications, but would a Bridgestone 020 (fr) and a Pirelli Diablo (re) work? Or would it upset the bikes stability. :here: :help:
