Question to you other guys who daily drive big 4x4 trucks. Does your front or rear tires wear faster?

 

even last time i checked (and rotated tires)

 

seems my rears are going faster, I guess I need to check alignment.

 

i dunno if ford explodition qualifies as "big 4x4 truck" though, cause that's what i drive.

I'd have the alignment checked for sure, j00r rear bearings could be going if it's off (and j00 have a solid axle)

 

With the Excursion, tire wear seems quite even. With my previous Suburban, the fronts (outside shoulders actually) seemed to wear a little faster.

 

Ditto on the Excursion (PSD, 4x4) - pretty even all around, even when I chase down ricers on exit ramps.

My '98 Dodge Ram 1500 4x4 wore the outside shoulders of the fronts a bit, but was still pretty even all around.

Rotate tires once or twice a year and you'll be fine.

The front geometry and weight of a lot of trucks and 4x4s really does tend to wear the very outer edges of the front tires, mostly in steering scrub. If you have very aggressive tread block shapes like all terrains or if you allow it to get out ao alignment much at all, this car really quickly create a feathering wear pattern in the outer tread blocks. becasue of this geometry and scrub, it really is more important on these big vehicles to rotate your tires as much as or more so than your normal street cars.

I have an '02 Explorer and my right front outer tread is wearing greatly faster than all the rest simply because I do a nearly 180 degree u-turn in my driveway to get into my garage and that tire gets scrubbed at the slowest possible speeds. I need to rotate again this week just becasue of that.

 

So Lee, is it a caster thing? I've sometimes heard of "fixes" to caster problems with big trucks, especially when I had my C2500 burb.

 

Mine wear even front to rear as well as sectional. Rotate " X " every oil change.

You need to rotate tires left-right between sessions, and dial in some more camber.

Before the smokey-burnout-doughnuts, my tires looked pretty even with 50k on them.

Still lots of tread back there, just not as much as the fronts. I'm trying to kill off the Firestones so I can get a bigger pimpy set of BFG's.

I don't really know as I have limited experience and less interest in putting those vehicles on alignment racks and chasing it down. Could be a number of things including caster, amount of sidewall flex, etc. in my situation, you can actually see many black turning marks on my clean concrete driveway and all of this was done at under speedometer indicating speeds, maybe the speed of a walk. Not enough actual suspension motion for camber to have any effect.
