A colleague says it is a best-practice to fill air in the car and bike tires once every two weeks. He says not doing so causes tiny wrinkles/cracks in the tubing and reduces the life of the tire faster.
Is this true? I tend to fill air in the tires only when I can feel that the air pressure is low (like when the vehicle moves over a road hump and I feel that the tire does not have enough air pressure).
What is recommended practice?
