They are lug centric, but corrosion is corrosion! I remember a truck shop changing an outside rear on my 4500hd, took over an hour, sledge, prybar, driving around the yard with the lugs half tight, and then someone finally got it off.

 

You certain? They sure feel like they were hub centric, could feel the rim sit down onto the center ring when I installed it. Also I just had one rim last week to measure it and it was only slightly wasier to get off than the rest. Hopefully pulling them off every spring/fall will lossen them up.

I know the pains of dually rims. I'm a fleet mechanic and have a bunch of f450 and 550s that spend their life in the mud. We've had two guys pounding away in tandem of each side of tire trying to get a set of duallys off.

 

nope I'm not sure lol. I always thought it was the hub/wheel design together that determined lug vs hub, that hub centric relies on the hub to line up the wheel and the lugs can be of a flat design. whereas the coned lugs line up the wheel in a lug centric.

But I just looked it up and that's not the case, that's what I get for being an internet mechanic lol

 

not sure what "hub centric" means, but I always put a coating of anti-seize on the hub contacting parts of the wheels when I rotate. I've had stuck wheels before, not fun.

 

Hub centric means that the flange(or hub) where the tires mounts on has a round ring protruding out. This ring slides snugly into the inside of the rim to center to rim on the flange. It gives a more accurate fit than tapered lugnuts do.

Because of this snug fit rims often get stuck on the hub and can be a bugger to get off.

 

I'm almost positive that our wheels are hub centric.

 

That would explain the difficulty I had finding rims. I figured it would be easy since the 1500 uses the same bolt pattern and similar back spacing but that was not the case. Selections were limited and usually a week plus wait time to order in.

 

I've been ok with my wheels, 108mm bore with 108mm to 78mm delrin or nylon hub rings.
