A few weeks ago I was checking the air pressure a day before our first trip. The drivers right front kept leaking from the stem and would only stop if the cap was put back on.
The air pressure was too low to drive on and wouldn't take air from the compressor. I figured the tire would have to be removed from the rim to be fixed.
I called a mobile tire service who came by. He looked at the stem, removed the old stem valve, put a new one in and aired up the tire. Now that I think back on it - as a kid how many times did I take out a valve stem on a bike. Totally forgot about it:S
Anyhow he said since he was there he might as well check the other tires - all included in the service call (they charge mileage as well as labour).
Total bill $156 CAD -(just over $100 USD)
I'm not upset about the bill, I should have tried to change the stem valve myself, just didn't occur to me then that I could. Expensive lesson, but they stick.
