Fix a Motorcycle Flat Tire

Step 5Second And Third Irons

Second And Third Irons
Repeat with your other two tire irons. You might want to put your knee on the first one to keep it from getting levered up and hitting you in the face. If that happens you've got other problems as well. Most likely the tire has re-seated itself on the rim and isn't loose enough. Push it down away from the rim all the way around and things should get easier.
This tire is pretty badly cracked from SUV pollution in the air. It was stored in the shade but wasn't covered. It cracked badly anyway. I'll need to replace it soon so I'm not being careful with it.

If you care about your tire you can lubricate the edges with soap like they do at a tire shop before prying it on or off. If you ask a mechanic at a tire shop for some of that grease-looking rim soap they'll be happy to give you some. They'll be glad that someone knows about it and interpret that as a sign of respect for their profession.

What was I saying about SUV pollution?
Pollution from cars turns into nitric acid and other crap in the air. (NO2 + UV + fog -> SMOG)
It dissolves and erodes marble sculptures, makes acid rain that kills fish in lakes in Canada, and makes a lot of stuff deteriorate faster than you'd expect. Why is there so much of it?
While Karl Rove and his little playmates had America hypnotized, congress voted in some really bad laws. Sport Utility Vehicles (SUV) which are giant station wagons, were classified as "trucks" because they weighed so much. "Trucks" were exempted from emissions controls. A tax break allowed people to "expense" the purchase of a "truck" on their taxes rather than "depreciating" it. That means anyone with business income could take money they'd ordinarily use to pay taxes and buy giant cars (SUVs) with it instead. General Motors made a fortune selling these tax-subsidized over-polluting gas-guzzlers. The situation was even worse than it seemed at the time. Our tailpipe emissions standards are measured in "parts per million". These huge engines pump out a whole lot more parts and millions. Children living near freeways developed athsma and other medical problems more than they would have in France or other more frugal countries. We invaded Iraq, which happens to have a lot of oil. When the crash came, GM was making gas-guzzlers that no one wanted. GM failed. We tax payers now own GM. And a lot of SUVs that no one wants. When we get "cash for clunkers" from the government we buy small foreign cars. Does anyone remember the 1970s? If you'd like to know what it was like, look around.
