You're absolutely hopeless, and don't really know what you really want because you don't know what you really need.
If you're going to race on pavement you're going to want soft compound street tires, not hard compound dirt tires, and if you knew anything about tires, you'd know you gotta get temperature into them to make them work to their full potential on pavement. If you go too wide or use too hard of a compound, you'll never get the magical grip out of them you're expecting. If you're going to go racing, you'll want to reduce the rotational inertia of your unsprung masses, IE wheels and tires, not spec out tires meant for jumping a 300 lb dirtbike 50 meters with a 200+ lb rider.
The chopper has pedals, and the street moped has pegs, because where I live mopeds can have pegs no problem.
Please don't weld your frame up with a gas torch, especially if you're expecting to crash into potholes at 50 mph and expect the frame to take the shock loading without suspension. Use an inert gas shielded MIG or TIG welder if you are so deathly concerned about your safety that you're selecting wheels and tires that can handle the load of Fat Bastard riding a CR500 off a motocross jump.
Like I said, less talk, more action, and get over yourself to read how tires and two wheeled vehicles work before you make something you regret.
I'm done with you, get to work and post real updates in your thread.
