What is everyone's opinion on using a pyrometer on street stock tires??? We are new to street stocks on dirt. I though that it would be a quick way to see if anything major was wrong with the chassis? I was basically just wanting to know if it will help on street stock tires. Thanks for your replies..

You can learn a lot from your tire temps. Like if your camber is set correct, if you have the proper tire pressure, and where your rear bite is. I would say it is one of the best setup tools for the money.

- When in doubt, hit the gas.

I agree a pyrometer is a vital tool.
First thing i do when i pull into the pit after a race, jump out, grab my gun and clipboard...before i even take off my helmet. Read those temps.
I will add that the infrared gun types out now are much easier to use, very affordable and i would recommend them I have a cord type tool too, just prefer the gun. And oh yes i have compared them, they read within a degree of each other.
Important thing with gauges is use the same one the same way to measure relative changes.

Cross weight is the # 1 reason I use it. Sure I can see tire pressures too low. Camber? My biggest problem there is trying to decide if I want even tire temps across the tread, or as Paul VanValkenburgh suggest to have the RF inside 5 to 10 deg hotter and the LF's outside 5 to 10 deg hotter. His suggestion is for asphalt but I still wonder. Any, way -- I run 'em even. But, as I said before, the biggest area is getting the cross dialed in for the car and even though you should be able to see it -- the pyrometer paints a clear picture of over or understeer vs a balanced car. Also, I use a Longacre memory pyrometer that holds all the temps on the screen. FYI -- I saved well over a $100 by buying it at a Kart shop online vs traditional race shops.
