I purchased an infrared heat sensor gun from harbor freight and occasionally check my tire and wheel temps on stops while on the road. If any are not similar to the others you will know to investigate further.
I have found many uses for it, such as air temps from the AC, heat from the floor registers, and etc. for inside the trailer. I used to use it on my racecar checking exhaust from each header at the head to determine cylinder temps. A misfiring cylinder would always be cooler. A screaming hot pipe could indicate a lean condition.
