I think I am finally ready to pull the trigger on a wheel tire combo. I have already ordered new OEM valve stem replacements (AC Delco 15263240) and will use the existing TPMS sensors with them. This is for a 2017 2LT RS with front brembo's square setup, let me know if you see something wrong/missing...

Is 255 the optimal tire size for a 20x9 rim?
