If you have a tire pressure monitoring system (TPMS) on your vehicle, you still need to manually check your pressure once a month, before you take a long trip, or if you notice any problems with your tires. Your TPMS is designed to let you know when it detects under-inflation at a preset level, but extra wear on your tires and poor fuel efficiency can occur well before your TPMS alerts you. If you do see an alert from your TPMS, you shouldn’t continue to drive more than 50 miles before having your tires checked or exceed speeds of 50 mph. Book an appointment with Ramona Tire as soon as possible.
