Another note for considering a tube, is most have steel stems that are real long. Universal i guess for multiple aplications. That steel stem breaks off real easy in mud or ruts. I even welded a piece of pipe around the stem to protect it like a skidder on a atv trailer i have that had old leaky tires on it. It still didn't last very long before it cracked

 

on my suzuki I have mud lite..worse tire maade..lol..but it split on the side wall..about an inch...I went to NAPA and got a truck innner tube patch..it was 4x4 inches...I ruffed up the inner tire and applied it....then i tubed it...used a liquid rubber to sorta fill the crack so nothing can enter it....its been good for close to 2 years now...I think the liquid rubber was made by Duro or maybe 3M..worked good to seal the crack....
