Yep definitely a must.....'specially if you had some heavy handed Acadian with the air wrench running off live air from the two stage, put your tires on..........LOL!!
Seriously though...those wimpy wrenches are designed, lengthwise so that the "Average" human can deliver the correct torque to lug nuts/bolts. And remove them as well......but as we all know nobody uses them to put tires on or off except in an emergency....where they may or may not work depending on who put the wheels on. Very frustrating if they don't........what is even worse is when you get all the nuts off but the "wheel center to hub " fit is so close that they rust together and the wheel won't come off even after you've struggled the nuts off.....in the dark.....in the rain.....in a wild fit.......yep... get a really big cross wrench...LOL!!!
