Did bad shocks make these tires bald?

What caused this wear?

    So oem tires at 30k miles, some would say that is all the are really good for? What say you to the cause of this? Two back tires bald in center, 2 front tires still like new. No I didn't rotate, I always planned on getting new tires just didnt care like I should have, but admittedly took too long to do it. Now they are worthless on craigslist, I will keep them for spares or yard art.

    I always thought it was freeway driving with tailgate up putting downforce on them. The book says over inflation, but I never was above 35psi like ever! You have to be at 35psi to clear the TPMS so how could that be it? Could be alignment maybe? Interesting, my tire guy said it was the shocks, mind you the shocks only have 30k miles on them as well. He said he could tell by the way the wear was bumpy, and he has been doing this for 8 years, I think it is possible, but I think the tailgate is to blame, hard to say, convince me your opinion. I put new shocks on front pretty soon after buying the truck, but never did backs, something I will be changing. I think kyb for backs, bills up front.

    That looks like a tire pressure problem, shocks usually cause cupping or irregular wear. I've seen this on trucks that see excessive speeds, tow heavy, and with high tire pressures.
    Not saying you're any of the above but It really does look like over inflation Usually shocks cause nasty cupping.[​IMG]

    In my experience that is over inflation I know you said the tire pressure monitor system won't let you go any less than 35 but with my 2500 they want to see 80 a in the rears even if I'm empty which is ridiculous. I only run about 45 in my rears empty. And my tpms light is allways on.

    I have to agree with that being over inflation. I think you did good getting 30k from those tires. I only got a little over 17k out of mine. I didn’t mind because I couldn’t wait to get rid of those low quality tires. If you’re replacing the struts and shocks I would use the same brand front and rear so the match and work together properly over mixing brands.

    Too much psi. If it was a shock issue
    Your tires would would cup while getting bald.

    The low load rating tires like these say max air should be 35 psi, I think I buy what you guys are selling. I just have a hard time fca forces 35psi to clear psi warning, lol. My new tires can take up to 85psi, but ride nice on the 45psi I am running on them. Maybe a combo of that plus tailgate plus low quality shocks, but I buy the main issue or culprit is psi. I wont be abusing the new skins like I did these. However, if it was only psi, then why would the front tires not look the same, they literally look like zero wear? All were kept right a 35psi for the entire time, it has to be multi issues. Maybe the down force from tailgate really wears when the psi is at max and there is low quality shocks?

    Because there is more weight over the front tires. With no weight in the rear of the truck less psi is needed. Now if you would have been rotating the tires you wouldn’t have noticed it.

    The factory tires are Paper thin It's pathetic! In a 60 mile stretch if dirt road I killed the factory tire with a rock and then killed the factory spare. It was a bit of an ordeal. Running 12ply and never had any issues since.

    I didn't even get to 30,000 miles on my original tires. They wore out very unevenly. Ever since new tires put on about 20,000 miles ago, no issues with uneven wear.

    What's even more amazing to me is that those are the original tires and your truck is 10 years old and only has like 30K on it! I thought I was doing good with 37K on my 2017. Do they have any dry rot on them?
