I"ll take that chance, monster trucks are meant to have big ass tires. I refuse to believe that 2200kv will have a hard time powering 40 series wheels with the torque that thing puts out...
I like big wheels as well, hence why I've still got them on my Muggy, but you have to gear down to keep your temps down and keep from over drawing.
All I ever wanted was an honest weeks pay for an honest days work.
