#1 - I have a game cart with 20 inch pneumatic tires with inner tubes. Try as I may, I cannot get them to hold air even with the puncture resistant tubes. I would like to replace them with new rims/tires that do not require air. I know they won't roll as easy as pneumatic but I am fed up with flats. I am leaning toward sticking with 20 inchers because they will roll easier than the smaller ones plus my cart came from the factory with 20 inchers. Any suggestions on replacements? Also the axle diameter is 5/8" and not 3/4" like most carts so I would need a bushing of some sort too.

#2 - If I decide to replace my cart with a different one, based on the criteria below, what would you recommend?

1) I am a solo hunter with lower back issues (bulging discs)
2) 2-3 mile retrieval distance
3) Quartered or de-boned elk retrieval
4) Early season - snow not an issue
5) Mostly two track dirt/small rock roads - behind closed gates
6. Cactus is present

Thanks for the help.
