Adding air

[Grog]

Here's the prob...New bikes (only have 60 mi on them) but need air in tires. Bought a pump from ****'s Sporting Goods but when I aftering adding air and removing valve, air escapes before I can get the (*^%% thing off. So I check the pressure and it's back down to 80 or so.

Make sure you're pulling the pump head straight away from the valve, not in a diagonal movement.

You can try with your valve at the highest position on your wheel and pulling straight down.

Please give more details about the pump...
