Lug wrench - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Rotated the tires on my truck Saturday . First time since the tire shop put on new tires . I have a 20" 4 way lug wrench and it was all I could do to break the lugs loose . I tork mine to about 100 ft lbs and this was way over that . Just wonder if y'all had run into this before and if you have a cheater bar on your wrench ? By the way I'm 6' and too close to 300 lbs .

Some tire shops put the lug nuts back on with an impact wrench and does not check the torque.

It happened to me once when I was on a trip and had the tires rotated at Sam's Club.

I always use a torque wrench. Depending on the vehicle and the wheels, I usually go between 75 and 85 ft-lbs.

I went to a tire store one time and said to the guy, "Do you use a torque wrench to tighten the lug nuts?" He assured me he did. Then I watched as he cranked down the lugs with the impact wrench and went behind it with the torque wrench. Of course, if your impact wrench puts 150 or 200 pounds of torque on a lug, it's not going to be hard to reach 75 with the torque wrench.

I have this happen a LOT at tire shops. They put the lugs on with an impact wrench and tighten them WAY too much.

I just had new wheels installed today. Torqued to 110 ft lbs. with a torque wrench not a air gun!

THANKS for all the replies . I used to take off my wheels and leave them when I needed new tires . May hafta go back to that . Sure glad I wasn't on the side of the road with the O.E lug wrench when I found out my lugs were way too tight .

I was putting together a little 4WD (insert import name here) for a friend who was overseas. Had some friends pick up the tires I had bought and had mounted and they put them on the vehicle for me before I got to the shop. Later, we had some problems with the brakes and couldn't hardly remove the lugnuts. They tightened the lugnuts so tight (probably with an impact) that it distorted some of the brake parts and goobered the wheels where the lugnuts seated. Been using the impact to run them down to so-so tight and finishing with the torque wrench ever since.

Now I drive home from the tire store, loosen the lugs, and give them the proper torque with a torque wrench.
