Tires - wear patterns

[CuzEd]

Looking for help identifying tire wear cause and replacement tires for my truck.
2016 Ram Laramie, mega cab 4x4, 6.7 Diesel with stock Firestone transforce AT LT 285/60R20/125/122E tires.
Hauling Forest River COACHMEN Catalina 283 DDS
Equalizer 4 point sway control system, 10k
Level hitch height verified by Camper Clinic
Front tire pressure 65
Rear tire pressure 75
Already replaced 2 tires due to excessive wear in rear tires, outer edge. Admittedly didn’t rotate enough and had long haul from Texas to California and back.
We load the truck bed with a heavy load when hauling to MTB Races, and boondock slightly off roads so thinking more 4x4 tread than stock tire. We are not light haulers, and often have full tanks when traveling.
Truck has always had drift ( lateral squish for lack of better term) when hauling, new tires, and under all towing but exaggerated in wind.
I have noticed other Ram trucks(same as Mine) with same wear pattern, but fifth wheel. Love to hear what you think I should do/ get.

Excessive tire wear on the edges would indicate either you're exceeding the load capacity on the tires or you're riding with insufficient tire pressure.

What's the load range printed on the tire?
What's the max pressure as indicated on the tire?

[007matman]

Nm.. I found it.

I'd try running them at 80psi (which should be the max psi allowed on those tires.

Is your WDH dialed in properly?

I bet you're exceeding the load capacity of the vehicle with your bikes and the trailer.

If be looking at a 3500 Dually.

Running tires at 80 ps in rear. I will look at total weight and make sure I’m not exceeding it but not going to dually at this time. Already moved up from f150 as they said the 2500 would be more than enough. Funny thing is the fifth wheel having the same wear pattern. Must be where the load is centered. Thanks for the response.

My opinion....

Find a GOOD front end shop and talk to them. I assume you have searched the internet for a "cause"?

I have a 2005(which could be totally different) and I have ZERO tire issues and have 200K with all factory parts.

The camper you have there is probably around 8k, right? Figure 10% of that is on the hitch so there is 800lbs there. How much does your bikes and other equipment weigh? I'm guessing you probably have another 7-800 lbs easily there plus add in your occupants. I'd be really surprised if you weren't way over your payload capacity there. It's actually pretty common with a 3/4 ton truck.

A Dually would really be the only way to get around this issue. whoever told you to go with a SRW either didn't have all the facts or didn't realize how much everything weighs.

If you're not willing to get a new vehicle I'd just expect to eat tires. You could try changing out wheel and tire combos to get something with a stiffer sidewall. I'd talk to your tire shop about that.

A front end alignment isn't going to assist with tire wear in the rear as you've got a solid rear axle there (no alignment needed in the rear).

Good luck! Sorry man you're having issues. I totally know what it's like.

I think one of the key words here is "Stock Tires" I burned thru the "Stock Tires on my 2013 Silverado in 2.5 years. Didn't even make 40k on them. Already replaced the "Stock Tires on my 2014 GMC Duramax at 45k. Currently running with my kids Stock Tires from his 2018 High Country till I decide on a suitable replacement. Stock Tires are Goodyear.

These tires are noted for excessive tire wear and if your lucky you may get 25000 miles on them before replacing. I have those on my new truck and have 5000 miles on them and will be replacing with non off road tires shortly. Even my dealer service manager replaced the same tires on his 2016 with Michelin tires and the truck rides so much better. Later RJD

I too agree think it is the Firestone tires. I have been towing trailers for over 40 years now. In that time I have had Chevy products, AMC Jeeps, Ford Explores and a Dodge pick-up truck. With these products I have had Goodyear, Firestone, Michelin, Toyo and Nitta Dural Grappler tires for my towing needs. Some were sent on the truck as original equipment and some I purchased as a replacement tire. With that been said the worst towing/driving tires, I every have had were Firestone tires. They have never lasted the miles that they were rated for and I could even feel the tires squirming when driving either towing or not. My current towing tires are Nitto Dural Grappler tires and by far these are the best tires I have own for towing. I do adjust my tire air pressure from 70 PSI rear when I tow to 45 PSI not towing. The front air pressure is 55 PSI all of the time.

I now refuse on buying any vehicle with Firestone tires on said vehicle.

P.S. my TPMS is disabled on my truck, the aftermarket tires and rims do not have any sensors in them.

Those AT Firestones are known to wear fast.

I used to run the Firestone Transforce HT tires on all my highway trucks. Would get an avg of 45k miles which was excellent for this price range. Then something happened and the avg went to 25k for a set of them.

Never had any uneven wear patterns. No clue in what is causing that for the OP. Something has to be wrong somewhere I would think.

Now running Cooper Discoverer HT3. Happy so far and a set is even cheaper than the transforce

stock tires - have poor tread life span. if you get 30 to 40 thousand on them you are blessed.
I take mine off every truck I've purchased new and wither put them on a rack and when the time came reinstalled them on the truck for trade in value or sold them for 2/3 of a new replacement set.

Ok,being in this field for over 40 years I don't believe your truck is overloaded.
Outside wear only on both rear tires is leading me to believe the rear end may be out of wack. If you were severely over weight and causing the axle tubes to flex, you would wear the inside edges. I would look for a good alignment shop that will set up for a 4 wheel align and can check rear diff set back. This would tell if the rear end was cocked. Forget the large tire chain stores, they only want to set toe angle on vehicles and really don't do much with caster,camber,and set back. Most don't even know what the angles are. I would
also add rear airbags. You won't believe how they will they will change the ride and add stability to the vehicle. You'll no longer have body sad or front end wander. Good luck.

I have the 20" Firestone Transforce tires on my truck...I have 28K on my 2015 RAM 2500 of which 7K are towing it isn't my daily driver they still have a good 40% tread life left on them.

I see no reason I wouldn't get 40K out of them they and they are wearing fine. I keep 80lbs in the rear and 70lbs in the front at all times...I rotate them every 5K...It's a truck not a Rolls Royce for what and when I use it the ride is fine
