I have been using an Infrared Laser Thermometer for about a year now. It works very well on tires, exhaust manifolds, calipers (I diagnosed a stuck caliper when the temp was about 10 F. hotter than the others) and many other things around the house.

Even though the tire surface cools quickly, you can still check the temps across the tread with an infrared thermometer (and on the sidewalls) to get a very clear reading of what is going on. You can also use it to check caliper temps to check your brake system (something you cannot do with a pyrometer with a probe), exhaust temps, A/C temps...
