Why does a team sometimes use another teams wheels?

Question

Kevin Harvick rode around with chrome wheels after he got wrecked and his car never runs chrome wheels so why would he use another teams, don't they have their own?

Answer 1

he may have traded wheels with another team  tires have series and lot numbers and things and some teams want a specific lot of tires

Answer 2

I know in the truck series they do this often because they are only allowed to purchase a certain number of tire sets but its completely legal to simply buy tires from teams that have expired from the race.  If Harvick did it Sunday Im guessing they were in test mode at that time or some kind of a deal where they took another teams tires and rims to test things out.

It is true though that chrome rims create and retain more heat.  Thats why black rims are mostly used .
