you wont be needing my rivit gun again then Chris? :P lol,

Yeah it might not be worth it seing as you have wide wheels and 4 off them..Bike tyres are good and if done correctly can look cool...But vulkan can have advantages.
I think storm 2 has always had vulkon but originally it was way to hard to grip the floor...he had a softer vershion put onto the metal wheels...Is there an even softer vershion you could get put on?..
