New Tubes
Bought some new tubes today, after pumping them up to max pressure I can feel a soft spot on the top of the tire above where the valve stem is. Is this normal, never experienced this before. The tires are 700x 30 Kendras, tire look to be in decent shape, could I have gotten the wrong size tubes..

Are the tire's beads completely seated in the area of the valve stem. Sometimes the tube gets caught between the tire's bead adjacent and the rim adjacent to the valve stem. If this happens you can push the valve into the tire while deflated, this will remove the tube from under the bead(s).
Or maybe you just have a defective tire.

no i didn't leave the lever in and the tires are both seated . I was looking at the box i bought 700x19-25, and the tires are 30;s would that make a differnce. Both tires are soft, meaning i can push the tires above the stem farther into the rim then elsewear. The rest of the tire is hard to the touch but around the stem.

Hmmm. Try this:
1. Partially deflate your tires. For this you'll want them almost flat.
2. Push the valve stem straight downward. 1/4" will be plenty.
3. Now reinflate your tires.
The inner tube immediately adjacent to your valve stem is a little thicker than the rest of the tube. If that thick section gets caught under the tire beads, the beads won't seat against the rim like they do over the rest of the tire.

This step should always be done when installing tubes; of course RG knows!
