my wife replaced the tube while i was at work yesterday( had someone do it) ride home seemed fine.Patch the tube. You can't effectively patch a bike tire. A nail hole won't matter unless it's torn or it's so large you can see the tube through the tire once it's inflated.
the rear tire that was punctured was alot more worn through than the front, so
last night i switched the rear tire to the front with the new innertube, and the then front tire to the back with the old one.
went for a short 20 min ride last night, everything seemed fine.
woke up this morning, and its flat again. wife is picking me up a replacement tire and another tube, and if i get back and check to see if the tube is leaking from the same spot where the hole in the tire is, ill get her to take the tube back and get me another one( cant have enough spare tubes !)
if they wont take it back ill patch it and keep as spare.
