Darkside Part 2

Here are some of the questions I can answer about putting a car tire on a motorcycle.
1]  Are you CRAZY?
     Debatable, not that I can tell. I installed this tire after research.
2]  Did you modify your bike to accept a car tire?
     No. the OEM tire is 200/60-16. I installed a 215/55-16. The last number indicates wheel size in inches. It fit the stock wheel.
3]  Who installed it?
      I did with the help of a friend. You have to do this yourself, or find a mechanic who will do it in their off time. A shop typically will not install something not designed for its intended use. no body wants to get sued.
4]  What kind of tire is it?
      General Altimax HP (V rated)

I also want to clarify the economics. I mentioned in an earlier post that the motorcycle tire was $290 and the car tire was $120. The prices are correct but do not reflect the true "value" of the car tire. A tire that is designed for a motorcycle is made of several rubber compounds. typically, a hard compound in the middle and softer on the sides. Because there is only two points of contact between bike and pavement, the motorcycle tire is designed for grip. They grip very well but don't last. Motorcycle tires usually last on average 10,000 miles. I had to replace mine after 6,000 miles. Back to economics, $290 tire for 6000 miles is 4.8333 cents per mile versus a $120 tire rated for 40,000 is 0.3 cents per mile.
