I get paid $10 an hour to fix flats, mount new tires and perform the odd oil change. Doesn't really seem worth it, does it? Well, I suppose you're right. It's not. So, I insert wee paper bits of interesting ephemera into your tires before remounting them. So long as these tidbits don't affect or harm the integrity of the tire itself, all bets are off.
To you, Godspeed.
And to the next tire monkey down the line, keep the faith, brother.
