I tried my best to follow that principal.

Made repair kit with tube, tools and patch kit. Mounted Road Morph to chain stay. Replaced $12 Nashbar slicks with Schwalbe Marathon Racers......

Less than fifty miles later......rode past a construction zone. Picked up a piece of roof decking in the new rear tire big enough it would flatten the tire on a big truck. Flat within seconds--first one in several years. Local cop stopped to check on me, I told him that I be OK as soon as I got this in and unrolled my pre-talc powered tube. He went on. Tube was for road bike, I was on MTB. Called wife she offered to come get me. ​Told her no, just letting you know that I'll be late. Patched tube and rode on. Missed the machine-gun effect on the rim side and had to pump up three or four times on way home.

Now, I have two, correct sized, tubes and the patch kit. So far, so good.
