We re checked our temps with the IR thermometer yesterday on this trip since we realized the readings we had were on the ST missions and we now have LT Coopers. We have the pressure pro monitor system. The readings are variable and dependent on the outside temp, tire pressure and speed.
Yesterday the outside temp was 90/91 speed was 62/65 MPH and the tire presure was a exact 80psi on all tires. The tire pressure monitor saw a high reading of 90/91 psi with the average being 88/89 The tire temps were 120/121/121/120 and the hub temps were all 118. That was with the pressure monitor showing 91PSI. I would have liked to have shot the road temp but coud not do that. The Mission ST tires ran a bit cooler than the LT's. Later in the day the outside temp dropped to 84 and the tire sat at a steady 88 psi.
