Dually rear tire wear

Cummins 12v98 I think you will find your Ram has gear type power transferring limited slip differential. The torque generating from the Cummins I6 is a lot lower rpm than the V8 diesels therefore it will wear rear tires quicker especially if inflated to the max. This of course will be amplified by more aggressive driving styles. Just saying?

I agree. I am not a lead foot off the line. I like to open it up once in a wile after getting rolling. Amazing that 9K can be hitting 80+ entering the freeway.

I am reading that front tires wearing fine at 27,000 miles.

Rear tires almost worn out.

If so this is strange to me. Just changed tires on my dually and all were worn the same (front and back both).

I used to run 10 lug 22" wheels with Nitto Terra Grapplers on my '06 Dodge dually. I never rotated them. Mine would pretty much wear the same way. I'd get close to 40k on them with no rotation whatsoever. The very first set that I had on there, I was surprised too, that the rears were worn more than the fronts. But I had figured out that because they were the drive tires, that would wear faster,...especially since it's a 6 sp manual. Like was mentioned in one of the other posts,...you don't need to use max inflation,...especially on the rear. I would always run 70 fronts, and 55 in the rears. Every time I get my oil changed, I always have to tell those guys to leave my tire pressure alone, because the wanna put more in the rears than in the front.

Diesel's put out a lot of torque to the rear tires don't accelerate so hard it just peals off rubber.

I blame the posi rear and the diesels torque. When I accerate while turning from a parking lot or stop sign the inside tire always skips.

You must be hammering it! I never have that happen under normal conditions.

It does not have a Posi.

Some people lay the hammer down all the time and that is why they rarely see 40K on a set of tires.

I have 27,000 miles on Ram dually and the rear tires are worn down to less than half tread left fronts are fine is this normal with dually's. I always keep tire inflated to the reccomended pressure.

Keep in mind that steer tires don't wear much if the vehicle isn't turning, but the drive tires are applying torque for a long distance and that torque causes tire wear.

So it shouldn't be surprising to see the drive tires on a tow vehicle wear faster then the fronts.

OEM tires are not the best quality and seem to wear faster than replacements. Also hauling a heavy load increased the rear tire wear. My rears wore faster than the front but I tow a heavy 5er.

That's the exact opposite of my experience.

The OEM tires seem to wear a lot better and a lot longer.

I would have agreed with you until my current RAM Dually with POS General tires. 2/3 worn out in 25K.

25K on MS2's now and they still look great.

2nd gen Ram BFG's and Michelin's I would easily get 100K and more on my 98 2500 RAM/Cummins 4x4.

I run 75 in front 65 in back as per the door panel tires are ameritrac tr

Never rotate my tires and always get 45-50k out of my rear tires- and that is all-terrain or mud-terrain tires which wear faster than the stock stuff. Front last about 30k but again- I don't rotate.

I run 50 psi in the rear and for long trips I will fill them to 60 psi. My trailer weighs 23k loaded and has about 5k in pin weight. No way anyone ever needs 80psi in the rear duals.

You are doing way too many burn outs! :)
