Pressure assistance that comes to your vehicle.
Request an on-site pressure check and top-up
Mobile Auto Diagnostics offers tire inflation assistance at supported, accessible locations. Send your ZIP code, vehicle information and a description of the tire concern so we can check the appointment before booking.
Let us know whether the tire still holds air, whether more than one tire is low, and whether a low-pressure or TPMS warning appears on the dashboard. A visible puncture, sidewall problem or tire that is completely flat may call for a different service.
Use the vehicle’s specified pressure
The recommended inflation pressure comes from the vehicle’s Tire and Loading Information label or owner’s manual, not the maximum pressure printed on the tire sidewall. NHTSA also recommends checking pressure with the tires cold for an accurate reference.
The pressure-check and inflation request is separate from a request to diagnose a TPMS fault. Sensor programming, replacement and relearn procedures are not automatically included in a tire top-up.
Inflation is not a tire repair
Adding air will not fix a puncture or structural tire damage. This service does not include tire replacement, tire mounting, wheel repair or a guarantee that the tire will hold pressure.
Share the condition as clearly as you can before booking. If the tire is damaged or unsafe to drive on, arrange appropriate tire service rather than treating inflation as a permanent fix.
Do not drive on a visibly damaged or completely flat tire to reach an appointment. Tire damage or repeated pressure loss needs appropriate professional attention.
