It's not useless information. It "can" be helpful if you know how to use it to your advantage.
For instance, a tire that is creating more temperature is working harder, ie getting more of the load/grip.
Ex. If the RR is getting all of the temperature gain and no temp gain in the lr, then it may indicate too low of cross, wrong percentages, too quick of transfer, too much stagger, or something else.
You can also look at temperature gradient from outside to inside of the tire. This, along with pressure gain, can be useful to better determine correct stagger, camber, and air pressure needed in the tires.
Ex. The RF being hot on the inside edge would indicate that you could be running too much camber, or that the kart is pushing, ie too much left wheel input keeping the weight and footprint on the inside edge of the tire rather than more evenly placing the tire in the track.
With all that said, the parameters we are used to tuning within will vary little from low to high. Unless you've got something way off on your set-up, you won't see big differences in tire temps. A 30*F difference from left to right rear is very typical, even on low bite tracks.
I'm a firm believer that ALL data can be useful -- just that some is obviously more useful than others.
