New at replacing tube
#1
ok, i never fixed a flat tire before...

so the sizes on my tire say: 700 x 25c (25-622) 28 x 1 5/8 x 1
and the tube i bought says: 700 c x 23-25mm 27 x 1-1 1/8

when i to buy it, i only remembered the 700cx25 size,
i understand that 700x25 is the diameter and width

but what do the other numbers mean? do i need exchange my tube?

it sounds like you have the right tube. A 25c is a skinny tire.not sure what the c means.however
the relation between the 23-25mm and the 27x1-1/8 is inches vs. millimeters
25.4 millimeter = 1 inch
1. take tire off rim and rub knuckle on inside of tire to feel for any glass, thorns or whatever
2. bead one side of tire on wheel the right direction for your use
3. puff your new tube a little with air
4. insert the stem first and put on cap
5. push stem into tire and start beading tire at stem then pull stem back down
6. finish beading tire being careful not to pinch tube
7. inflate 1/2 way, then let out air and pump up again just a little
8. then make sure your tire bead is seated even spin it and look at it
9. pump to correct pressure
good luck
