Taking SCARY out of used bikes, one bike at a time.
This is a common issue. (mostly on Schrader Valves) What happens is the tire pressure gets too low air pressure and the tire slips. First it makes it very challenging to air up plus the rim could cut the tube.
It’s a easy fix. Just let all of the air out of the tire. Shift the tube and tire so the Valve is at 90 degree and air back to pressure. There will be a pressure range stamped on the side of the tire. (example: 45-65psi) Fill and check weekly to the pressure range. Too low will have tire shift, and possible pinch flat and/or rim damage. Too high the tire can blow off the rim. (BOOM!!!)
So for tire safety make sure the valve is correct and air up to pressure range.
