New high quality tire doesn't sit evenly on the rim
The tire sidewall is just hung up on the rim a little. It’s a common problem. 

Deflate the tire until you can deform it a little with your hands, rotate the wheel so the problematic section is at the top. Grab the tire from the side and lever it back and forth. You should be able to pop it out so the bead sits on the rim properly. 

BTW, a pressure gauge is a good investment so you know you are inflating your tire to the proper pressure. 

Here's a link to Park Tool's video on tire installation, at the point it addresses the bead being too high or low.
