9)What is worse?

Part 3-Final Question(Worth 10 points)

1)Does the numbers in the michelin dh tire line up mean anything? Explain. Umm I live in Florida we don't have hills to go down so how the heck sould I know? I'd hazard a guess that it has some thing to do with tread depth or something.

Multiple Choice

1.) l.

2.) d.

3.) b. (?)

4.) c.

5.) e. (guess)

6.) b.

7.) b. (?)

8.) a.

9.) b. If your front tire "washes out" your front wheel will turn and/or your bike will fall over. If your front tire slips, your weight will move forward where if your tire turns to the left, your bike will go to the left, but you are not prepared for it so you keep going straight. When your rear tire slips, it is alot easier to control where your direction will not change as rapidly and it is easier to put your foot down to control it.

10.) e.

True or False

1.) False

4) c
5) e
6) b
7) c
8) a
9) b because you have much less control if your front tire slides and you have more of a chance of stacking if your front wheel washes out than your back wheel due to the front being your steering wheel

Explain. i'd have to say front, because i've had my rear wash out on me before riding on off cambre stuff... and i'm always able to regain some sort of balance or brace myself for a fall... having the front wash out, i can only picture myself going over the bars or doing some sort of face-plant, which doesn't sound too appealing to me.

8. True
9. Sure why not, True.
10. False

Part III

1. Well, what number. If I recall correctly there are LOTS of numbers there. The tire width (which is closest to correct on Michelins). There is also compound, tire pressure. What numbers might you be talking about. :) YEAH!

They probably do. Numbers probably represent, in an order the code for the compound, air pressure, size, width and height or something.

a)Wide on front, narrow on back

9)What is worse?
b)Front washing out due to loss of traction.
Tail washes tend to be a more gentle crash than a front wash. Tail washes I found your side gets hit, front washes tend to more often be the face getting it. From a pure traction point...the front tire is what does most of your steering, and if it goes, you lose steering input entirely,and are left to hope it bites before you crash.

Oh btw, this will be cumulative.

Will you be grading on a curve? ;)

I'm not sure what number your talking about, but Michelins have, size, width, Durometer rating and I think they have a batch number.

Ok, quiz is over.

In general, the scores were pretty good. Next quiz will be in November.
