I had a tire develop a bulge on a recent trip out of state. Found a BF Goodrich dealer in a small town that had one in stock and did the warranty then they went to install it. I asked them to use a torque wrench on the wheel lugs. Watching thru the glass I saw the guy hammer the lugs down with the impact and never used a torque wrench. When I said something they said "That impact will get em tighter than any torque wrench". Not much I could do then but wondering if I should anything now? loosen them off and re-torque? Forget about it and get on with life? Are the studs stretched now? I have the factory wheels, alloy I think, and about 1,500 miles since the wheel was put back on.
Well you certainly can't argue with their logic, huh? Ha ha. Re-torque to spec is about all you can do if the concern is there. What is the torque on those? Do you have a torque wrench that goes that high? The shops have to get stuff done quickly, is what it is. Air tools can be torque limited but it's an open question whether they used them, or keep them calibrated for that matter.
Those studs will take a lot on these trucks. 165ft lbs is the spec but most of the impact guns will go more than that. I would loosen and retorque merely for the fact that if you get stuck on the highway, you will be extremely unhappy trying to remove the wheel with the manual lug wrenches.
The only problem we have had is getting them off while on the side of the road with the Ford provided lug wrench. If they are really tight it takes two people. One to hold the wrench straight, the other to jump off the top of the truck onto the wrench. Better performed by the Flying Wallandas......
More concerning to me is the fact that I've had 2 of those BFG Rugged Terrains develop a bubble in the last year along with 3 on a co-workers truck.
Mine are 265/75/16 and my coworker is running a 285/70/17 so it's not even narrowed down to a certain size.
What's the deal with these Rugged Terrains?
I am not sure but mine are about 4 years old but only have about 10K on them. The one that got the bulge was the same one that my granddaughter slammed into a HUGE pothole with a few months back and I attributed the failure to that, although it took a while to develop. I knew something was up just outside Las Cruces when the cups in the cupholder started to jiggle ever so slightly.(the tire was rotated to the rear before we left). When I checked it you could see tiny pieces of rubber starting to come off. Slowed to 55 and by the time we hit Deming it was a romp romp romp when slowing down. I told my wife she is lucky I am in tune with my vehicle, many would not notice anything until it came apart.

On my first set of Mud-Terrain KM2 tires one of mine separated (bubbled) at the end of tread life (about 35K miles). It was noticeable before but I thought I had other issues and didn't figure it out until the tires were pretty much done. Discount Tire replaced it under warranty. I was hesitant to get any more since I was at a 25% failure rate (my first BF Goodrich tires). Wit the new tire I bought 3 more and gave it another try. I'm on my 3rd set now and still only have had that one failure out of 13 tires (I bought a spare the first time around since I oversized compared to stock with 285/75-16). They are the best tires I've owned for what I want (on- and off-road) and will continue to buy them. My dad has been using BFG AT tires on his Chevy 2500HD since he got it 8 years ago and has never had a problem with his tires.
I've seen lug nuts torched off because they were over-tightened and could not be removed. That rim looks awful purdy. Be a shame to have to scorch 'er.
No idea on why the tires bubble, never seen that on any of any of the vehicles around the place. When the E rated tires go to the flatbeds though they all give out eventually.
I wouldn't worry about tightening the tires with an impact, we've used that method on anything with tires for as long as I can remember. Never had a problem.
It is a problem on the small car econoboxes with tinny wheels, all the components are so thin the whole assembly is distorted when they get reefed down to the usual 12-15 yard/tons.
I like to torque wheel nuts "just because" and as mentioned it makes it a whole lot more enjoyable at removal time.
