Having a discussion with a co-worker today, about changing tires. I know of the formula for changing the pressure if you use a non OEM tire.
Inflation PSI = Z*X*35%/Y
X= Gross vehicle weight (lbs)
Y= max load per tire - as marked on sidewall (lbs)
Z= max tire pressure - as marked on...
I am looking for advice here. Should I be concerned with a pinhead sized paint chip? It was self-inflicted two nights ago with the end of a tape measure. I have attached a photo. I'm trying to apply just enough touch up paint so that it would blend in and not show from a distance.
