RE: The Official Traxxas Slash short-course race truck
I must have been thinking of something else. Those Badlands are 5" tires, so they'll rub the body like woah unless you cut a bunch of it off and raise it up as high as it'll go.
Badlands aren't exactly what I'd call "pin" tires. They're more for serious offroad, mud, and occasional rock crawling.
Check out the ProLine Gladiator 2.2 tires. And any 2.2 truck wheel with 12mm hex hubs (except some beadlocks) will fit the Slash.
