Wow ............... we sure are getting "nuts" if not overtechnical and overkill on torquing the lug "nuts" ............... ;)


Let me be get to the basics; unless you have a very precise high end calibrated torque wrench, most of the ones on retail (Craftsman from Sears, or the SK from Harbor Freight or Coastal Tool; and both seem to sell a similar one to TireRack as well) have a margin of error of +/- 4%. And yes, I know there are torque wrenches at $300 that have 1% margin of error ....... The reason why asked the question above is to see if the one from Tire Rack has a better margin - I suspect they are made by the same manufacturer but come better packaged at competitive price.


Thus, it is very possible that with a $19 to $89 torque qrench, you will have a variation of up to 8% difference in torque among the 5 lugs nuts on a single wheel. 8% of 80 is 6.4 ........... now for all the experts with this technical talk, does 6.4 make a difference? If it does, how to do you correct it ....  :confused:  ....... and if it does not matter, then what's the big deal ......... :p
