If you have/use a TPMS, there will be variances between the tires (temp & psi) due to the variances in the monitors on each tire themselves, whether cold or rolling down the road. IF it's a significant different (in your opinion), call the maker and discuss it with them to see what they say. Mine vary by a # or two per the monitor/sensors but all are in a range that I'm satisfied with.
