Tubed tires (like our KLRs) tend to deflate pretty quickly, while tubeless GENERALLY deflate a bit slower. The tubless tire has an inner liner that is somewhat self sealing (at least for reasonably sized holes). If you puncture a tube, even if it in a tubeless type tire, the air leaks out of the tube and out through spoke holes in the rim, the valve stem hole, etc. Hope that helps a little. Tom
