I have a Fuji bicycle that the inner tubes have started leaking. I read stamped on the tire: 37-622 (700 x 35C - 29 x 1 5/8 x 1 3/8)

I have found a tube at Wal-mart labeled: 700cx35/38/45 C A/V 35mm Tube (Schrader Valve) (2 Tubes)

Although I hate Wal-mart, will this work?

If the smallest number listed after the x on the replacement (35 in this case) is the same or slightly smaller than the same number on the original you should have no problems at all.

...but NEVER just throw in new tubes withiout determining why the old ones are leakiing -they don't really "wear out."

Before you start replacing tubes lets determine how much of a problem there is. For both tubes to suddenly start leaking is very unusual. All bike tires lose air and it is not uncommon to lose 10psi is a few days. How much are the tubes deflating and over what time does it occur.

Another consideration is that if you haven't successfully replaced tubes before then please look at one of the Youtube videos and read up on how to do it. Also you will need a set of tire levers...not screwdrivers.
