Over the winter I upgraded to a new bike which came with Metron 55 SL clincher wheels (inner rim 19mm, outer rim 27mm) and Conti UltraSport (25-622) tires. These are tubeless ready but I'm sticking with tubes for now.
When I changed my first flat I used a Race 28 (700c) Conti tube which lists compatibility of 20-622 to 25-630 so I think it's the right size, but when I feel the tire after tube inflation it seems like the tube isn't filling up the whole tire. Also, the tire is not seating properly on the rim, so when I spin it, it's clearly not symmetrical.
I'm not sure if I just need a bigger tube which would fill out the tire and seat it properly or if air is getting trapped between the tube and tire. Any thoughts would be appreciated. Thanks!
