[TR] Recommendation for an impact wrench

[Bob]

After inspection or tire shop visit on my everyday driver I need an impact
wrench if I need to remove a wheel.
They all use impact wrenches to put the wheels on.
I have the DW290 DeWalt, works just fine every time.
Regards,
Bob

I know that this is a stupid question to many people, but I shall ask it
anyways.
 
What nuts would a person use an Impact Wrench on? 
How often does one use this tool when doing any or each time of repair work?
