That's always a tricky question. I think you get a feel for it over time, but I inflate mine until the wrinkles are almost completely out and the tube is firm to the touch, requiring a little pressure to make a dent. From my experience, a tube will contract slightly in all but the warmest water (at least in my area) so I try to keep it on the tight side. But there's a fine line between inflated and overinflated, so be careful.
