1.5 inch tires are fine, especially if heavy rain occours the trail can get a little too soft for tires that are very narrow, especially with the load you will be carrying. Not much tread is necessary, slicks or semi-slicks roll much better.Make sure you are using kevlar belted tires, not folding tires with a kevlar bead, as many people do not know the difference. I rode the entire trail from west to east last week in four days with this set up on a cyclocross bike with no flats or problems...enjoy the peace and solitude of the Katy....
