jim t....on tube in tires...on the subject of rear tires, only the ones that have fluid in them, are the ones that i have put tubes in...main reason is to protect the rims from rusting, and as was mentioned earlier, so that if you happen to break the bead, all your fluid will not come out.( unlike your auto, it is preffered to keep your pressure low, so that you have a more smoother ride , and so that the tire lays flatter, which gives better traction. 5-15 p.s.i. should be enough), as for the front tires, i have been adding tubes as i replace the tires,because of problems in the past getting the bead to stay sealed, one tire fellow i deal with says it is the small rim size, and i have not had problems since i started to do it. Only other thing i can add here is that i have only seen one set of tires that came with tubes, come on a cub cadet that either myself or my freind have purchased over the past 10 years, that is about 15 cubs. so tubes in a cub cadet tire is not a common site, unless you happen to be at one of the plow days......one last note, i feel that adding fluid to your tires is one of the best ways to add weight to you cub, and be it plowing or pushing snow, or even cutting grass on a gental slope, with fresh morning dew, these cubs can use the extra weight
