Just a quick update here. At around 10am I figured I should put my old wheels on so that I can drive around today. I went out to the garage and started jacking up the car.
Then I realized that the tire isn't deflated anymore. Here's a recap :
1. Tire goes totally flat a block from my house
2. I spend 20 minutes filling it up and getting it to around 25psi
3. I pull into a supermarket and by the time I'm done buying a pizza of death, it's totally deflated again.
4. I drive to the nearby gas station and fill it up to 30psi
5. I drive home and it looks to be lower than at the gas station and is still making a hissing noise.
7. This morning it is at 30psi and looks fine.
My best guess is that 6 is "Midget ninjas replace tire, fill it up, slay my enemies, and then hide in the woodwork to watch my look of surprise when the tire is fine".
So now I don't know what to do. I kinda want my old tires back because the ride is so much smoother and they never go flat. Also I have 5 of those, but only 4 of my 19" ones. On the rare occasion that something goes wrong with my tires (*cough*), it's nice to have a spare. The 19" wheels are also worth a lot of money, so I could sell them.
On the other hand, the 19" wheels make the ladies swoon [note: this is a totally unverified claim], the tires on them are apparently monitored by ninja midgets, and choosing to keep these wheels means that I don't have to do anything right now. The car really does look better with them, though.
Unfortunately all of the pros for putting the old tires on are legitimate, whereas I made up every single one of the claims for the bigger wheels. I guess that means it's garage time. :( Goodbye big shiny wheels! If my car was clean I would take pictures, but it's not. It's filthy. Ooh! I will wash my car today too. Then I will show you pictures of the old wheels.
