Can you convert quick release to bolt on?
Check your bike axle: The primary factor determining if you can convert your quick release wheel to a bolt-on axle is the type of your hub. Bike models such as Shimano have axles that can easily be changed. So, the lock nuts and cone nuts from the quick release wheel cannot be used with the bolt-on axle.
Can you over tighten quick release?
you cant overdo it. You definitely can over do it and it can potentially cause damage to the qr lever if you do. The cheaper open cam skewers can be nearly impossible to over tighten, or even get tight enough unless you lubricate the interface between the lever cam and the concave washer though.
What pressure should my bike tires be at?
Pump it up. Proper tire pressure lets your bike roll quickly, ride smoothly, and avoid flats. Narrow tires need more air pressure than wide ones: Road tires typically require 80 to 130 psi (pounds per square inch); mountain tires, 25 to 35 psi; and hybrid tires, 40 to 70 psi.
