Checking the tires of the automatic gas scooters is another important aspect of maintenance. Inspect the tire pressure regularly. Under-inflated tires can reduce the fuel efficiency of the automatic gas scooters and also affect the handling and safety. Use a tire pressure gauge to measure the pressure and inflate the tires to the recommended level specified in the owner's manual of the automatic gas scooters. Also, check the tread depth of the tires. Worn-out tires with insufficient tread can be dangerous, especially on wet or slippery roads. If the tread is too thin, it is time to replace the tires of the automatic gas scooters.
