General Maintenance
Tire Inspection
1.
Inspect tires and remove objects (nails, metal
fragments, etc.) embedded in the tread of the
tire. Be careful not to cause further damage to
tire when removing these objects.
2.
Check tire for damage from chunking or heat
damage. This is a judgement requirement for
replacement. In general, if the damage is greater
than .5 in. (12 mm) deep and involves more than
4 in2 (650 mm2), it will usually affect the tire
performance and the tire should be replaced.
3.
Look for bulges or other evidence of internal
damage. Replace all tires that show evidence of
internal damage.
