My tires are 622 x 38C, and on the rim it says 622 x 21C (m̶i̶n̶i̶m̶u̶m̶ ̶t̶i̶r̶e̶ ̶w̶i̶d̶t̶h̶ ̶t̶h̶e̶ ̶r̶i̶m̶ ̶s̶u̶p̶p̶o̶r̶t̶s̶,̶ ̶I̶ ̶b̶e̶l̶i̶e̶v̶e̶ rim width). These tires cost around 18 dollars each.
I've spent some time on:
- making sure I haven't pinched the tube and there is no foreign object between the tire and the rim;
- deflating, adjusting the bead, trying to straighten the tire, reinflating;
The rim is true, the bead seems fine, yet the tire has a noticeable wobble (~2mm I would say):
This is how the bead looks:
These are the original components of a 170USD bicycle I bought from Decathlon a month ago. They have bicycle mechanics and a repair shop; but I guess they don't spend a lot of time fine tuning the bicycles before selling, especially the cheaper ones.
The front tire (which I haven't touched yet) wobbles a bit more; the rim is also 1-2mm out of true.
Will this tire wobble wear down the bearings faster, or other components? Or is this amount considered normal, and won't do any harm? Is this as true as you can get on such a cheap bicycle? Should I spend more time trying to adjust or leave it as it is?
