Inspection
Refer to Safety Precautions on
Whenever you check the tire pressures, you should also look for:
• Bumps or bulges in the side of the tire or the tread. Replace any tire that has a
bump or bulge.
• Cuts, slits, or cracks in the tires.
Replace the tire if you can see fabric or cord.
• Nails or other foreign objects embedded in the side of the tire or tread.
• Excessive tread wear.

Also, if you hit a pothole or hard object while riding, pull to the side of the road
as soon as you safely can and carefully inspect the tires for damage.
For the best performance, you should replace a tire before the tread depth at the
center reaches the following limits:
front 0.06 in (1.5 mm)
rear 0.08 in (2.0 mm)
If the wear indicators are visible, replace the tire immediately as it is no longer
safe.
