Rear tires wearing more than front?

[OldeBob]

2018 2500 4x4 Ram, 11,500 miles, 4,000 towing 10k FW, Firestone Transforce AT 285-60-20
I can definitely see more wear on the rear tires, and no cupping at all on the front. I have never seen this on previous trucks, and is the cause of this running TH with the EB all the time. I also have not rotated them, but will do that soon. Fronts have 13/32, and rears have 9/32. Thanks

Could it have anything to do with how much down pressure you exert on the "GO Pedal"? Just wonderin' ??

...but you do have 4 tires doing the work, instead of two.

YEA but they are SKINNY!!!

i just had a bfg AT RR tire failure

tore up rear bed at less than 24k, did a lot of damage was trying to get a few more weeks out of them

my mistake tread separation cost me a lot of moolah, insurance claim

glad 5ver wasnt on it

was going to replace 2 at end of job before pulling out front were new 4 months old pulling putting nittos all round now

paying a lot more attension to tire maintainance now

11,500 miles. No rotations. Towing and exhaust brake use.

I'd call it normal.

X2 on normal at those miles, rear tires have slip from torque from normal driving much less towing, rotate every oil change, check the pressures regularly, unless the frontend is out, the rear will always wear faster than the front. EB has no more effect on wear than normal braking.

EB has no more effect on wear than normal braking.

It certainly must....especially when towing. To have only one axle slowing you down using only the EB vs 2 or 4 axles (towing) using the service brakes, it definitely affects tire wear.

 

[Dl5treez]

Drivetrain retarders, whether they be engine compression, exhaust, hydraulic, or electromagnetic, will affect drive tire wear. It's simple physics, enhanced by light truck tires not being very long wearing to start with.

Especially with a single rear wheel.

One thing I haven’t seen mentioned here is using throttle while turning. I try to make a conscious effort to “coast” around corners so that the diff isn’t trying to engage the helical gears into trying to lock up due to different tire speeds. By this I mean tight corners in town and parking lots etc.

MOST people overinflated their rear tires and under inflate their fronts.
