The first time I changed a tire I was also at home, which was a good thing because it took forever and I couldn't get the tire seated right on the wheel so I gave up, let it sit overnight and re-did it the next day.
I'm still not very fast at it but have been able to help a few folks deal with flat tires on various rides. This weekend I'll be ride marshall at a ride for the National Law Enforcement Memorial, so I'll expect to be putting my skills (or lack thereof) to work again.
A couple of tips I learned recently from an experienced friend --
- After removing the wheel from the bike, turn it around slowly to look for signs of a puncture. While turning it, pinch the tire to help unseat it from the rim.
- When putting the tire on the wheel, line up the value stem with a marking on the tire, such as the first letter of the logo. This will make it easier to find the hole in the tire to remove any embedded sharp objects after you've located the puncture on the tube.
