Wheels are ROUND
Why is that so many products do have round wheels, not matter how many sub divisions or surface changes i make, the whells still look HEXAGONAL, this so dispointing so frustrating and dam right anoying trying to get a whhel to natulay look ROUND as it shoulod be, i have tried the roundness, smoothnes, radius, and evything to get a round wheel to point i have feel i have to delete the object , it's as though the content creator really dosn't give a flying boot about whells that should be ROUND. Is DAZ not botherd about the content it provides to its customers, that might be a harsh thing to say as most of the products are exceptional, but come on WHEELS ARE ROUND and not Hexagonal, and for me DAZ should be teeling its vendors the same before they sell the product, even if its a free product.

Essentially that is the result of working with 3D mesh, all you have is points in space and straight lines between those points.
I think rectangular wheels would be better as you wouldn't need a handbrake to keep the car in place
I find it odd smoothing groups don't work, I can smooth jagged edges easily in Carrara, iClone and Blender, I am only guessing there is something we are overlooking in D|S as it should do it too.
Convert to SubD, then use edge weights (through the Geometry Editor in edge selection mode) to sharpen the edges you don't want smoothed..
SubD should work, as long as you have the item selected. Whata re roundness and smoothness settings you are using? Those are not SubD properties. in any event I would doubt many items, even quite old items, have only six segments to a tyre.
I using both the subd and the suface editor, but i noted you mention edge weight through the geomerty editor, learn some new evry day, i will give that a try, thank you.
How completley and utterly stupid can I be, I feel like I just ran a race after the race was run 10 years ago, feel absolutley thick ( ok i know most of you will now agree ) but i thought the subd section was alreday part of the prop as theer is a section for the subd in the parameters tab, I was using this untill i just realised that it was grayed out even though i could change the values and take of the limits, only to find you still have to apply the subd for them to become active, so I now have to Hide under the table , eat humble pipe, and appoligize for my rant about vendors and props, ( and now I know most of you will rolling around in laughter . and yes i cannot spell either, or is that ither ). One click and the issue all sorted, guess I will now hide away before coming back to the forum so that people can forget the stupid one(and hoply not rember I posted this).
if wheels werent round , the ride would be bumpy
in poser terminology, think i twas called the crease angle
Now I want a car with square wheels...
I am not sure I see what the problem is?

The problem is vendors are too lazy to add square wheel morphs to their products...hell I will never again buy a car model that only has round wheels
Square wheels aren't a problem, as long as you build your roads properly:
And, seeing how some roads look after a harsh winter, I'm curious if some road planners are trying to get us to switch to square wheels.
It's time for a sing-along, I think.
The wheels at DAZ go round and round,
Round and round,
Round and round
very cool.... as long as your only turning left
ooohhh .... and another thing i realized besides wheels being round is that water is wet.
Would perfectly well if you had a cycloid shaped road surface of the right frequency.
On a serious note, I kinda know how the OP feels, even tho it should be easily fixable with subD (although in some cases subD makes older models look horrible). It's probably the main reason I make my own models higher resolution than they should be - I just can't STAND seeing model faceting, but I DO appreciate a modeler taking the time to keep the resolution as low as possible. Unfortunately it goes both ways - too high res or too low. :P

A good reason to make flying cars.
I guess you need nurbs rather than polygons to get real round shapes. Nothing that DS supports.
Well, at least, you don't need parking brake.
That's a long time ago I heard about nurbs. Nurbs.
That would reduce braking distances considerably.

Hovercrafts, man, them the future. Where we're going we don't need wheels.
The way things are going... boats is the future. Where we're going we can't have wheels.
yeah in Carrara I would just whack in some splines
they either export pretty jagged too as obj or very highpoly
Who knew this song would become the literal truth?
Those of us who live on boats nod and check the bilges.
Venice is a truly futuristic city. Time to get my Gondolas license.
