Are you willing to bet your life on the skill level of some mouth-breather with an impact wrench? All my auto mechanics students get the "torque every wheel nut" lesson drilled into their heads from day one in the shop. No, a lot of torque is NOT better. I hope I'm somewhere else on the road when the wheels start coming off the "just crank 'em down" guy's car due to broken lug bolts!

If a spec. isn't available, some rules of thumb should apply:
7/16" lug bolts- - - -65-70 ft./lb.
1/2"/12MM lug bolts- - - -85-100 ft./lb.
9/16" lug bolts- - - -110-125 ft./lb.
5/8"/16MM lug bolts- - - -125-140 ft./lb.

Going noticeably over these numbers risks bolt stretch and breakage. Much below those numbers will risk loose lug nuts after driving a while.
