>>1821038>wheel has a bump nowsounds kind of familia 2 me
if the bulge is near the valve deflate the tire fully and make sure the valve is not seated too deeply into the rim
the center channel on some rims is too small to make room for where the valve is attached the the inner tube (allow maybe 3 or 5 mm of room)
other basic things to check are the condition of the rim tape, (you dont want any ripplese or creases) and if the spoke heads are protrudeing though / makeing bumps
and that the tire has no cracks or debris
my practice is to slightly inflate the tire before installation, idk less than 10 psi
then carefully pry the wire beads onto the rim makeing sure that the inner tube does not get pinched (big problem when installing kevlar bead tires)
once both wire beads are in place go around the tire and roll it back and forth to help locate the inner tube in between the beads (and not underneath)
if everything looks good I inflate to 30 psi while keeping a carefull eye on the bead to make sure that if the inner tube escapes I can quickly deflate the tire before it pops
the bead only really starts to settle into place at 60 psi, it will make a creeking sound as it moves
my tires are 23 mm wide and rated for 152 psi, but I only put 80 psi in them, running tires closer to their maximum rateing seems to cause problems for me
>>1821054iirc
tire size has the width listed first
23-622
wheel rim size has the bead diameter first, and then the inside width of the rim (normaly about 2 mm less than the outside width)
622-13
and some notes from reading though boreing ERTO books
622x13 rim - optimum tyre 622x23, don't exceed 622x25
622x15 rim - optimum 622x23/25 but don't exceed 622x28(though a lot of people use 622x32 on these)
622x17 rim - 622x25 to 622x37 best is 622x28 or 622x32
622x19 rim - 622x28 up to 622x47 or 622x62 for some, I'm told 622x32 to 622x42 run best on these - to be honest not many frames will allow clearance for much more than 622x37
