2018 Ram 2500 Rear Tire Wear

[rpowers99]

I purchased a new 2018 Ram 2500 Laramie Crew 4x4 6.7 short bed about 18 months ago. It came with Firestone LT275/70R18 Transforce HT. At the first 5000 mile service the tires were not rotated because the rear tires were worn worse than front. Now I have a little under 12000 miles on the truck, and the rear tires are slick, and I will be replacing later this week. I use it to pull my Flagstaff 528RKS 5th Wheel, but only logged about 2000 miles (5 trips) pulling the RV. The remainder I have accumulated running errands locally, etc.

I run 60 psi front and 80 psi rear per the manufacturer recommendation. Thinking about going with 60 psi on all, except when pulling the camper.

Anyone else experienced a similar situation with tire wear, and determined what the cause may be? Thanks

Do you have the HT's or AT's? It's known the factory supplied Firestone AT's don't last long, the HT's are supposed to be better. 800ft lbs and exhaust brake is typically the cause, but are they worn evenly or only down the center? The 80 PSI in the rear is too much when empty and will cause them to wear down the middle faster. I run about 60 front, 50 rear most the time. That's sufficient as per scale weights, my tire size and load and inflation tables.

12000 miles on tires and they are slick?!

I had trouble with Firestone and Goodyear ATs on my SRW Ram 3500 4x4... early wear all the way around. I was getting something about 20K per set. I was towing quite a bit, though. Of the 100K on my 2014 RAM I had probably 60K+ of towing Windjammer 3001W This time I have Coopers on and (so far) wear is much better. (Offhand I can't give you the specific models on anything, other than all terrain.)

I have a 19 with about 15000 miles, I noticed yesterday that mine are wearing pretty bad. I suspect I'll get another 10k out of them, but, not much more. I have read that these tires are garbage, so, it's not too surprising I guess. Keep us posted on what you switch too.

Tires designed for All Terrain have too much void in the tread for good wear for highway use. Not enough rubber on the road.

Probably great for a muddy forest service road or pasture, even deep snow. Just don't expect them to give as many miles when driven mostly on paved highways.

I run this tire on my truck and replace as t about 50% wear. Last set went over 50k.

More than enough traction in Snow or the kind of dirt roads I drive on. I leave the deep mud for the youngsters.

Those high torque engines eat those cheap tires fast on the rear, try Michelin Defender and rotate at 5000.

I had a 2003 Ram 1500 Hemi did the same thing. Too light of rear and torque. Just curious is it a short or long bed ??


Just a side note the fastest wearing tires I have ever owned are Michelin's. Last 3 sets I owned 20K they were worn smooth evenly though. Never again. Got more miles out of cheap tires.

Just passed 10,000. Rotated at 6K. I don't see any issues with the tires. I run 80/80 and whatever they end up in the winter, maybe 65. 2018, 6.7 crew. I run the EB on full all the time except running on the highway.

I replaced the stocker GoodYear SRAs (20”) on my 2018 Denali HD after 25,000 miles.
Pulled heavy with these Defenders several times now with great results

My truck came with Michelins and are rotated at 5000 miles with oil change. Going on 25000 with hardly any wear showing. Even wear on all 4 tires.

9000 miles on my Ram, rear tires are the same brand and size as the OP, no unusual wear noted yet.

I was told when I first got a diesel Dodge 20+ years ago... the front tires wear excessively because of the "weight of the engine". I learned after owning one a while that the "weight of the accelerator" is what wears the tires... rear tires that is.
I suspect(not accusing) people who only get 10-15K from tires may drive differently that I do... I drive like an old man..heck I guess I am.
My buddy said... you know how it was to ride with your grandfather? I said yeah. He said that's how it is to ride with you. Man your tach never got over 1800. I just laughed and had to agree.

On a lightly loaded truck, empty bed I run 45PSI in my rear tires and 60PSI in the fronts when I have the Michelin tires on, winter. For my summer tires I run 50PSI in the rear and 55PSI in the front. But these are heavier tires and rims than stock with a higher load rating.

My tires are rotated every 5,000 to 6,000 miles and I will get about 60,000 mile wear life on my tires. They usually age out before they wear out.

My truck is a 2008, Mega Cab 6.7L Cummins 4X4.

Good point, your driving habits wear tires out. Might we ask what kind of fuel mileage the OP gets?

My Stock Firestone Transforce AT's lasted 32K...I replaced them with Continental TerrainContact AT I only have 3K on them half of that is towing and I would recommend them

[mwdilday]

I have over 36,000 on my Michelins on a F-350 dually and run 65 psi in the rears and 75 in the fronts as per the sticker. My rears are still good for another 30,000 or so.

80 PSI is too much pressure for a rear tire on an empty truck. you will wear out the centers of the tire.

on my 1998 Ram 2500 diesel, and my 2006 Ram 3500 SRW I used to run as low as 25 psi empty. (to TPS systems)


But on your 2018 2500 you can't run that low because that government mandated tire pressure warning system will turn on the dummy light.

But over 10,000 GVWR trucks, they don't have a warning system, so you can lower the tire pressure on those trucks.


I have read where you can get that TPS feature adjusted (aftermarket only) but around 2018 I think they locked the aftermarket out of the ECM.

Those Firestone tires are the worst I've ever had. Mine were also worn out in less than 6 months. Couldn't wait to get rid of them. Replaced with Coopers. No tire problems since.

All you need is an extra cable.
