Past 4 days:
Get nifty new air pump with nice pressure gauge. Fill up tires to try out the pump, works good. Next day going to ride, find the bike has a front flat. Replace tube. Replacement goes flat immediately, similar puncture on rim-side of tube. Put strips of electrical tape on area where punctures occur. Replace tube again (last tube) Go for a ride, park it in the garage.

Next day, rear is flat after sitting in the garage (WTF). No more tubes (10 on order). Puncture on rim-side of tube. Patch tube, replace, patch does not hold. Fail, park bike.

Get other bike (sequoia). Air up tires, go for ride. Come home park bike. 30 minutes after returning, hear a loud noise in the garage. Investigate, not sure of cause.

Go to LBS, buy 1 new tube ($6 vs. $2.95 online). Buy new rim tape to prevent rim-caused punctures. {now lunchtime today} Install new tape on rear wheel. Install tube on new bike rear wheel, puncture in the inner part of the tube (against the rim) somehow. Goes flat immediately. $6 well spent.

Look at other bike (sequoia). See rear is flat. Look closer. Rear is completely exploded… figured out what the loud noise in garage was yesterday.


Plans:
Throw nifty new air pump in garbage. Keep fingers crossed tubes come in the mail TODAY.

You do know they make patches for tubes?

I have had repeated epic failure when it comes to patching tubes, so I usually just rely on a new one.

I have a big box and can drive by your place tomorrow ... fill 'er up! :p

Figured out my problem. I was WAY overinflating. The gauge on my new pump is total crap. It's off by more than 20psi. I got out my trusty tire gauge for the car = 38psi. Used the air pump gauge = 18psi. So, when I was inflating my tires to the 120psi range, I was really more like +140psi in them. Not sure if this completely explains the punctures on the rimside of the tubes, but it definately explains the one that turned into a hand-grenade.

New tubes did come in the mail today, fixed both bikes and inflated without paying attention to the gauge, everything seems good.

FWIW, the gauge is a Sette tripod floor pump from pricepoint.

Care to name names?

It's a Sette Air 2 ST-001 Floor Pump w/ Tri Pod Base. Only bought it because I ordered a fork from pricepoint and it was on sale for $10, originally listed as $45. Now I know why. It does inflate well, just can't rely on the gauge at all. I haven't contacted pricepoint about it, and am not sure I will... it was $10.
