Wheels and Tires

Maintenance Problems

Check condition of wheels and tires. Remove any embedded objects. 
Report excessive wear, breaks, "chunking out", or bond failure. Check 
lug nuts for proper torque. Watch for loose wheel bearings.

Do not operate a truck that has a maintenance problem. Park the truck 
properly and remove the key, if equipped. Put an "Out of Service" tag 
on the truck. Report the truck problem to the proper authority.
