While on a cross country flight, you perform a bad landing at an unfamiliar airport....the result is that you apply the brakes too hard and skid one of the tires until the bias cords are showing where there had, in the past, been tire tread. You decide, correctly, that the tire has become unairworthy. For the record, the airplane is a Cessna 172N. Cessna Airplane Company is currently owned by Textron Aviation should you wish to look up something that would require knowledge of the manufacturer.

Since your flight was on a Saturday, there are no mechanics available, but there are other pilots. One offers to loan you tools and jacks and has a tire that he says will fit your airplane.

1. Can you install the tire yourself (why or why not)?

2. How would you determine that the offered tire is the right one for the airplane (caution....don't assume that the last person actually installed the correct tire, so maybe looking at the old tire isn't a good response. For the record....since you couldn't resist, you looked at the old tire. The damaged tire on your airplane is a 600-6, 4-ply tire....and the offered tire is a 600-6, 6-ply rated tire.
