Hey guys I was wanting to get some feedback on a couple of designs I was working on. I'm rather new to solidworks and cad in general so please be gentle . Would you want these on your z? ALL feedback welcome.

The two designs you have seem somewhat heavy and clunky. The Z33, with its high beltline and overall proportions, would not look good with either of these wheels IMO. But good luck and keep trying!

On a truck or suv and possibly newer domestic, on a z... no.

Yeah I knew they looked heavy. Ugh, it's just so much work cleaning the excess metal out haha. If I thinned it out though, would the design work or am I trying to make a snake into a lizard? I'm not very artsy, so I know they leave a lot to be desired.

To me, the z looks good with 2 kind of design on the wheels. Either a multi spoke or thin split spokes. 5 spokes can work if theyre thin.

I hate to be a Debby downer but from a performance stand point you have it backward. by widening the spokes as you go down you are adding a lot of rotational inertia. polar moment of inertia is a function of mass x distance^2. basically you want to keep them as light as possible towards the rim. additionally each of the spokes will act essentially like a cantilever beam meaning that the highest loads and therefore stresses in the spokes will be towards the hubs. since you have the cross sectional area of the spokes decreasing as you approach the spokes this will cause the stresses to increase even more.

keep trying though

I'm assuming you haven't gotten this far into the smaller details of the design yet, but right now there isn't a lug nut in the world that could hold those in place. A big pan head screw however....

jk. Just counter bore those holes and it'll look a little nicer.

Thinner spokes and more concave and you'll be all set on the first one. The second...uhhhh I'm not really feeling it.

Draw the wheel in profile and then revolve it.

This is an RPF1 I drew from memory while getting to know the software.

Nice rpf1, offsets look to be +40 though.

It's +15, it just looks off because the hub area isn't thick enough and the spokes need a little more curve. It was fairly close in mass though :-) I was just modeling anything I could think of while practicing for the certified associate exam. I only spent about 10 minutes on that one.

Wheels are definitely easiest to draw as a profile, then revolve boss and extrude cut the face with a circular pattern. Nice thing about that method is you can save the blank wheel and just change faces to experiment.
