New Rims have 2 Holes for TPMS/Valve Stem
So title explains all;
our tpms is inside of the valve stem (as far as i know; my aftermarket ones are for sure) so what about the 2nd hole? Apparently it is normal to have 2, but does the tire shop put something there or something?

Two holes for rims are standard for race applications, especially when you get into good quality rims.
The reason is to have 2 valve stems. You put a digital meter on one stem, and pump in the air, to be extremely accurate in regards to air pressure.

aha i see.
Also heard that the other valve stem is included in mounting price so no worries then. Was wondering if i had to buy something to fill it or anything

Everything is in a new size, so how do I determine new tire pressures I need to run?
30/35 were oem but it can't be the same...
