Tire Installation Process
Once the tire has been mounted, the remaining tire installation steps prepare the complete assembly for use on the vehicle. Here is what the broader tire installation procedure can include:
Step 1: Complete the mounting process
The mounting and bead-seating steps are completed first. The tire is now securely fitted to its wheel and ready for additional installation checks.
Step 2: Balance the assembly
The mounted wheel and tire are placed on a balancing machine, which spins the assembly and detects areas where its weight is uneven. The technician then applies or attaches wheel weights in the appropriate locations to correct the imbalance.
Step 3: Replace the valve stem
When appropriate, the existing valve stem is replaced with a new one. This can help reduce the risk of slow air loss associated with aging or deteriorated valve-stem rubber.
Step 4: Check the TPMS
If the vehicle uses a tire pressure monitoring system, the technician checks the sensors and confirms that the system is functioning properly. A reset or relearn procedure may be needed after installation, depending on the vehicle.
Step 5: Reinstall the wheel
The balanced wheel and tire assembly is fitted onto the vehicle's hub. The lug nuts are tightened according to the manufacturer's specifications, typically using a calibrated torque wrench and the correct tightening sequence.
Step 6: Set tire pressure and perform a final check
Each tire is inflated to the pressure specified for the vehicle, which is typically listed on the driver's side door jamb label. The technician then completes a final inspection to confirm proper bead seating, wheel security, tire pressure, and overall fitment.
Following these steps is an important part of proper tire installation and tire installation safety. While the basic process may look straightforward, professional equipment and correct procedures help ensure the tire and wheel assembly is prepared safely before the vehicle returns to the road.
