At Les Schwab, they used just the impact wrench and said this is how they do it throughout the chain. They felt that the impact wrench was unnecessary.
Who is right?
If that's how Les Schwab does it "throughout the chain" methinks you should avoid Les Schwab.

I recommend that anyone who bought tires from Les Schwab have their wheel lugs checked and tightened with a torque wrench...(which any tire shop that knows what it's doing will have... and use)

My 22.5 inch Monaco wheels are torqued to 450-500 ft lbs.

My 16 inch aluinum trailer wheels are torqued to 120-140 ft lbs.

My 17 inch Saturn Vue wheels are torqued to 100 ft. lbs.

All wheels will have a torque specification no matter who makes them.

Plus all tire shops that install tires will tell you to re-check the torque in the next 50-100 miles. That is a CYA statement in case the lugs loosen up for any reason.

I have never found a loose lug nut after they have been correctly torqued to the specification listed above.

When having the two front tires changed the mechanic at the Loves truck stop the mechanic had me observe his use and measurements with the long torque wrench. That made me feel very good about their expertise.

Jarheads with air guns can stretch lug bolts and nuts. We worry about tire pressures, why should we not get the bolts correct?

When I had tires put on the Dutch Star they used a big, long torque wrench and they guy was pretty large too. I also have a torque multiplier and with it I only need 154#s to get 500 ft lbs on the lugs.

LS did the same thing with my rv, slipped off the jack stands. Only damage was one crushed stainless wheel cover. I went for a walk while the young fellow worked on the tire change, and returned just after it happened. He was quite nervous, but I him calmed him by saying mistakes are made when you work for a living. We were on vacation at the time, but when we returned home there was a new stainless wheel cover on my porch.

Trouble is a lot of the time the torque wrench is just for show because the impact gun already overtorqued the nuts.
Easy to tell - just watch the socket when they use the torque wrench. If it doesn't rotate before it clicks, then the nut was already overtorqued.

The other dead giveaway for ignorance is when they don't even ask what torque you should have and whether that torque is for clean dry threads or lubricated threads. Those that slather some gunk out of a big pail all over the threads and rim with a big brush should be drowned in it as an example to the rest of the crew. If the spec was for clean dry threads then applying the spec torque to lubricated threads has probably way over stretched the studs by a factor of up to 3

And I'd bet your tyre pressures are 100psi all-round. Easy to remember.

The guy at Les Shwab just used an impact gun on mine.
What I was'nt impressed with, was he did'nt tighten them in a criss-cross pattern. Just started at 12:00 and went around the rim !!

Well gang,
As usual, generalities prevail. I've had the pleasure of dealing with two different Les Schwab stores and they not only were courteous and willing to get the job done quickly to get us back on the road but, they were PROFESSIONAL too. I watched as they jacked up the front of our coach, an '04 Itasca Horizon 36GD with the C-7 330HP CAT with two, air powered 20 ton jacks. ZERO issue there.

Then, they did the tire work/balance work and, remounted the 255 80R 22.5" Alloy wheels and tires back on the front with great care. They then spun all 10 lug nuts on each side very lightly 'till they bottomed out. At that point, they brought out the big 3/4" drive torque wrench. At that time, they let down both jacks simultaneously. The did the same exact procedure that I do when I remove and re-install my own wheels. That is, they torqued them to the 1/2 way point of the total torque required for those wheels/lugs. And that was 225 ft.lbs.

The torque wrench was reset to 450 ft. lbs. and, all 20 were retorqued to that setting. They were very conscious and aware of the highly polished wheels and took all precautions to avoid damage.

I'm not too sure I'd qualify that all Les Schwab outlets are operated the same. I was thoroughly happy with the service I received from them.

I never allowed a vehicle to leave my shop without the wheels being torqued. That's a bit different when you have to torque to 450 ft lbs but torque multipliers ot just the correct sized TW will do the job.

I was always skeptical for the torque sticks until last spring when I taught a class at the local Vo-Tech. My assistant owned an alignment and tire shop and he used the torque sticks and said they do work well. He checked them again accurate torque wrenches.

The most critical aspect of torquing is that all the lugs are torqued the same. Un-equal torque will warp a rotor.

Another reason why we torque. Bolts will come loose unless they are stretched but they can't be stretched beyond their elastic limit. That's why they come loose or break. If they are not stretched a certain amount they will come loose. Stretched to much and they will fatigue and break.


All going well with you FIRE UP???

Right, that sounds pretty accurate. Then of course you could use a 5' pipe and feed the kid 7 burgers (singles of course) which should give you about 525 Lb. Ft of torque +_ 72.5% More or less.

I have the torque stick and loaned it to the guy that put my tires on. I bought it for my use if I need it on the road.

I worked for a major OEM supplier of heavy truck hubs, Brake drums and rotors. We were curious about torque stiks and ran some tests. We found them to be very repeatable for one gun. Meaning, you would get pretty much the same torque every time with the same gun. Problem was, it wasn't necessarily the torque marked on the stik. And, with a different impact wrench, the torque would be different. It all stands to reason, since the torque delivered is a factor of the impact wrench's interaction with the radial displacement of the torque stik. Different wrench, different torque.

Bottom line? If somebody uses one of these things on your vehicle, double check with a torque wrench.
