26 x 1.95 will work fine. The '26' is the size of the wheel they fit on (you must use 26" tires - other sizes simply won't fit) but the second number is how fat the tire is, which you can choose as you like, within reason (huge tires might result in clearance issues, for example). 1.95" tires will be a little skinnier than your current ones, of course.
