I replaced the cruiser tires on my wife's Columbia bike a while back using some Cheng Shin tires (26 x 2.125). I just bought some more of that same brand to put on my Brittany bikes (26 x 1 3/8 ).
In both cases after I mounted the tires they seemed to be pretty out of round to the point that they feel funny when you ride the bikes - almost like a bulge in a tire. I turned the bikes over and spun the wheels and I could see how out of round they were.
In the case of the tires on my Brittanys they have a raised center tread section and that raised part even moves around on the tire so that it's not always centered on the tire as the wheel spins around.
So I'm wondering if it's just more Chinese junk that should be recalled - or if there is some trick to mounting the tires to keep this from happening.
I tried letting the air out and then pushing on the tire as I rolled the wheel around, and also using my hands to try to twist them to get the center tread straight on the wheel before I aired it back up. Neither thing seemed to make much difference and the tires were still out of round when I spun them.
I just put them on after they had been all twisted up in the shipping box, so maybe it takes time for them to straighten out once they are mounted.
So if any of you have run into this problem or you have a trick to mounting the tires to keep this from happening - assuming they are actually round and it's just my mounting job that's the problem, let me know.
Thanks.
