Tell me about inner tubes

[officerbill]

Just put a Shinko tire on the front, found out, at the shop it needed and inner tube. It never dawned on me some tires still need tubes. Bought the tube at the shop. Anyway the tube leaks, at the valve stem, it has a metal valve stem that had a nut to hold it in place. How tight should that be? Is something I can fix, or does it have to go back the shop?

The nut has nothing to do with leakage. Air is coming from around the valve stem? Or through the valve itself?

Did the shop install?

Around the stem, thought to tighten the nut but no good

yeppers, the wheel is going back for them to make right, but until I can get it there no bike to ride.

The tube is leaking somewhere inside the tire, the air comes out around the stem. They probably pinched it putting the tire on. Make them replace the tube.

My plan exactly

Yep. They pinched the tube. Don't let them patch it -- make sure they put in a new one.

In most shops, the new guy is the one who has to rassle tires, and Teddy the Teenage Tweaker gets a little impatient at times...

Yet another reason to Do It Yourself.
