Tire Pressure monitor alarm?

Hi Guys, Just wanted to get some input here. I was driving today and hit a nasty bump on the right side (both tires front and rear). Checked the rims and it looked fine (as well as for bubbles). There were none.

Later on that night (about 60 miles of driving later and 8 hours), I drove home all seemed to be fine, but as soon as I pulled into my garage, the TPMS warning came on showing 35 psi on both right tires and 36 psi on both left tires.

Is this something I should be concerned about? All tires have good tread and wear and the rear tires were replaced 3 weeks prior.

I hit the bump at low speed (about 15 mph) pulling into a parking lot. Obviously will check and rebalance air to 36 all around tomorrow morning.

They're the 20" staggered config on a 2013 S550.

Thanks in Advance.
