Sure. Ordinary cars can run for miles on just the rims so there's no reason a half-track wouldn't be able to. US half-tracks also had a powered front axle, which would help too.
what about the tires were they more rubber filled than air? I remember they were different than tires at the time.
Found this: http://www.usarmymodels.com/ARTICLES/Tires/tires.html Combat construction was adopted as standard in October 1941 (OCM 17285). They were developed as "run-flat" tires that would allow continued operation for 75 miles (eventually reduced to 40 miles) even after being punctured by bullets or shell fire (OCM 19747). These tires used significantly more rubber (50-60%) in their sidewalls to maintain rigidity, along with beadlocks, a metal band that went inside the tire and pressed the beads outward against the rim, which added to sidewall rigidity. (The beadlocks also prevented slipping on the rim.) Because of the rigid construction and beadlocks normal one-piece wheels where the tire was stretched over and between the flanges could not be used. A two-piece divided rim was concurrently developed that effectively split the wheel in two (much like most model kit wheels) and was assembled from either side of the tire. While it was possible to change a tire without removing the wheel from the vehicle using a divided rim this practice was apparently little used. Divided rims could also be used with standard tires.
They were also able to move without either track being on the rear. Not very fast or very far, but they could move.
Slip probably gets tired of answering this...or else he's done it so much, it is burned into his brain. Linky! http://www.ww2f.com/topic/23566-half-track-question/
I sincerely doubt that. I woke up from a weekend drunk and my "signature" was on the bottom line. I didn't see how I could get out of it.
