I have thought about making a hole in the pan to access the valve stem, not sure I want to do that. For now I just take the pans off to check tire pressure. This makes it a hassle to check -so I do it less (still about every 3 weeks). My car is one year older than TPS systems

so I have the plastic valve stem
What are your ideas for a 1 to 1.5" hole for valve stem access?
Looks?
degradation of function?
will a hole mess up the balance of the wheel?
