My trans temps never went over 185, the engine hit 223 for a few seconds when climbing a continuous grade for about 10 miles in AZ. There were signs along the highway telling people to turn the AC off to avoid overheating, no way! The 220s were short lived, the temps dropped back down around 200 quickly when the terrain leveled out a bit. The TPMS is a great investment, hopefully you installed steel valve stems when you put the new tires on.
