Walkaround focus
Inspect pressure with an appropriate gauge, tread condition, cuts, bulges, exposed material, rim damage, loose fastener clues and hub leaks.
Compare positions
A temperature, wear or inflation difference can reveal a developing problem even when each tire looks acceptable at a glance.
Driver takeaway
Do not drive on a tire or wheel-end defect that makes the vehicle unsafe; report the exact location and observed condition.
