I need two things. One of those cool hand-pump water spray bottles for my tires, and a pyrometer so I can finally dial in tire pressures. Where are these things sold? I checked Walmart for the spray bottle, but didnt find anything that wasnt intended for weeds that was specially built for weed killer. Any advice?

 

That's what I bought. A Walmart 2 gallon garden sprayer

And pyrometer you can get at Radio Shack. THey have infrared ones now. I have a needle type that you stick into the surface of the tire I got for $70.

 

What is a pyrometer? And how does it work. I'm quite interested

 

A pyrometer measures temperature.

You use it most on your tires. You want even temperatures across your tire which means you are using the whole tire effectively. If the shoulders are hot then you need more air, if the middle is hot then you need less air. Then you adjust the rear tire pressures to suit your driving style. More or less rotation.
