We invaded Iraq, which happens to have a lot of oil. Children living near freeways developed athsma and other medical problems more than they would have in France or other more frugal countries. These huge engines pump out a whole lot more parts and millions. Our tailpipe emissions standards are measured in "parts per million". The situation was even worse than it seemed at the time. General Motors made a fortune selling these tax-subsidized over-polluting gas-guzzlers. That means anyone with business income could take money they'd ordinarily use to pay taxes and buy giant cars (SUVs) with it instead. A tax break allowed people to "expense" the purchase of a "truck" on their taxes rather than "depreciating" it. "Trucks" were exempted from emissions controls. Sport Utility Vehicles (SUV) which are giant station wagons, were classified as "trucks" because they weighed so much. Why is there so much of it? While Karl Rove and his little playmates had America hypnotized, congress voted in some really bad laws. (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. What was I saying about SUV pollution? Pollution from cars turns into nitric acid and other crap in the air. They'll be glad that someone knows about it and interpret that as a sign of respect for their profession. 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. 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. I'll need to replace it soon so I'm not being careful with it. It was stored in the shade but wasn't covered. This tire is pretty badly cracked from SUV pollution in the air. Push it down away from the rim all the way around and things should get easier. Most likely the tire has re-seated itself on the rim and isn't loose enough. If that happens you've got other problems as well. You might want to put your knee on the first one to keep it from getting levered up and hitting you in the face.
