Pressures will always rise from cold temps to hot temps. 8* rise is quite a bit but if it's hot enough it's not unbelievable.

Pressure increase, especially in hot weather, is normal.

Realize, also, that the TPMS is not accurate to 1 psi.

Look at the tire. What does it say the maximum allowed pressure is? Are you getting a reading over that pressure? If not, everything should be okay.

30psi is the correct cold tire pressure.
Expect 1psi increase in tire pressure for each 10 degree increase in temp.

8 p.s.i. is a big jump. Your air supply should be "dry" with as little moisture as possible.
