Thanks for the info!

I choose the tires so i can meander throughout most terrain, i bash at a contruction site so its provide a wide horizon of types of stuff i can do. Sometime i'd do mud bogging, some times i want to hit a jump at full throttle, sometimes i just run around on plain, flat gravel.
So basically i do some stuff where i need lots of speed, and some stuff where i need lots of power...but mostly speed.

Hows 18-51 sound?
