  1. What should you do before every ride to check your tires?

    Inflate them to the correct pressure. Underinflated tires can be cut or damaged, so check pressure before riding.

  2. How much lubricant should you use on a bike chain?
    Show the answer

    Less is best, wiping excess. Use a bike-specific lubricant and wipe away excess so grit does not collect.

  3. When should you replace a bike tire?

    When it shows cracks or cuts. Tires with cracks or cuts are suspect and should be replaced for safety.
