Yep...all normal. When I first put a TPMS on my rig, it was after 2 blowouts 50 days apart with new tires. Turns out it was the tires' fault, and nothing I did....Goodyear made it right and I still run them...... with that said, my TPMS scared the dickens out of me when it started showing numbers like you posted, and I had just had the blowouts. I even pulled off the road and checked the tires to see if what the TPMS was showing was correct. It was, and the tires were perfectly fine. I found that having the TPMS added to my stress when driving, so I try not to look at it all the time.
What you want to watch the TPMS for, is abnormal and sudden changes....like a sudden drop or increase in pressure or a spike in temperature in one tire vs all the others. I've also found that the measurements that it gives are not absolute...mine tends to show a slightly lower pressure than read by an actual tire gauge, and whereas the air temp inside the tire is what the TPMS is reading, the tread temp is the main concern. I bought a laser thermometer and if I stop on the way somewhere I shoot the temp of the treads to see if there are any higher than the others, which might be indicative of problems with that tire.
