4.You put a penny head-first into your tire tread and can see all of Lincoln's head. What does that tell you?
- AThe tread is low, so grip in bad weather is much reduced
- BThe tire is brand new and has never been driven on
- CThe tire pressure is set too high for normal driving
- DThe tread is still deep enough to be safe in all weather
Show the answer
✓ A. The tread is low, so grip in bad weather is much reduced
If part of Lincoln's head is covered by tread, you have enough. If you can see his whole head, the tread is below about 1/16 inch and grip is greatly reduced.
