1.Walk me through how you'd mount and balance a tire from start to finish.
Why they ask
It's the core task. They want to hear the steps in order and catch anyone who skips the checks between them.
How to answer
- Break the bead, dismount the old tire, and inspect the rim for bends, cracks and corrosion at the bead seat
- Check or replace the valve stem, and handle the TPMS sensor gently so you don't snap it on the changer
- Lube the bead, mount the new tire, seat it, and inflate to the placard pressure on the door jamb
- Spin it on the balancer, add weights where it tells you, and re-spin to confirm
- Mention that you'd flag anything odd to the lead before the wheel goes back on
