Building up my daughter's old/new 1972 Motobecane Nomade recently, i was looking for 27 inch tires in town and found what I thought were my only options without going online. They were $9 a tire, and the only option to get her on her new bike for the weekend, so I ventured into a bike shop I've never patronized and took a chance. Check out the bulge on the sidewall. I used my silca track floor pump to partially inflate and seat the tube by feel, then later pumped a bit more to reach about 60, maybe 70lbs and left it at that. The Kendas are rated as 90lbs max. Later that night as the wheel rested against a wall, I started hearing odd sounds...
I've since found one other local option for 27 inch tires and am installing them tonight. i plan to take the Kendas (both) back to that shop. We shall see if they will accept the return and refund the money. I'm posting this mainly for the funky bulge aspect. With the tire off I can now feel the variable thickness of the sidewall at that area and notice the incomplete stamping of the sizing numerals.
