New tires rounded shoulder

[AGT]

Not sure what could cause it. New tires in back have the square shoulder but the front look like they might be rounding on the shoulder

 

Ball joints?

are they both rounding on the shoulder evenly? inside or outside shoulder? if so it might just be time to rotate them. how many miles on the tires?

Front tires will wear the shoulders simply due to turning. Front tires get pushed on turns, rear tires just follow along. Watch cars in parking lots to see what I mean about tires being pushed on turns.

Its even wear and not drastic. Outside shoulder. Only had em on a couple months. Definitely not cupping.

I have that problem too. The 6.2 just makes me take the curves to darn fast.. LMFAO

[KMGZ400]

its normal. i drive about 60-70,000 miles a year and i go through a lot of tires and its normal for the tires to start to round out on the outside edges. rotate them so they wear evenly

Thanks guys. I am on a few forums from old cars I used to have to bodybuilding and others, but this is my favorite because you can have a good time and laugh it up but still get informative details when needed without getting hailed on with comments of lack of knowledge. Thanks GM-Trucks

Yep, I agree with the others. As long as they're not cupping, I would't worry about it. 4wd trucks are hard on front tires. Keep them rotated.

How much air pressure are you running and are you setting the air pressure with the tire COLD?

 

I always run a bit more tire pressure than factory spec and watch the tires for even wear across the tread and adjust accordingly.

As long as they are wearing evenly, no worries. I never rotate tires (2wd), I let the fronts wear out, and move the rears to the front when replacing. I always follow up with a wheel alignment.

 

By not rotating, I minimize the chance of having the lug nuts cross threaded, or warping the rotors due to improper pattern an over torque when installing the lug nuts.

That's why lug nuts should never be put on with an impact gun. I've been on the wrong end of an overtightened lug on a truck. Last time I ever let that shop work on my vehicle. Should be spun on by hand then tightened with a torque wrench in the proper pattern. I've never crossed threaded a lug and never heard of a rotor warping from improper wheel install. I'm not trying to sound critical just wanted to throw my 2 cents in the game. No insult intended, especially since I used to do the same until I started driving 4wd's as my daily drivers (10 years ago).
