Ohhh Solidworks, how I love you so much. I have to use Inventor here, but essentially the same thing

Yeah, I'm a huge fan of Solidworks. I used Pro-E in school and hated it.

Sounds good. If there is truly some interest in these I will build one of each design and work out any potential issues that I might not have thought of. That way you guys aren't the guinea pigs.I would also be interested in a 2 or 3 design

I would love to be a guinea pig...hehe

I vote this:
#3 looks really cool but #1 seems like the most practical

Update:
Today I ran an analysis called FEA (Finite Element Analysis) on the first rack that I posted to check and see if it was strong enough to hold 250 lb worth of wheels/tires. For you non-engineers, this is where you break up the different parts into hundreds or thousands of tiny 3D elements. These elements are all connected to one another at points called nodes. Then 10's of thousands of deflection equations are solved simultaneously to output a deformation at each of these nodes. From there you can figure out many other things, stress, strain, factor of safety, etc. to help decide if the parts are strong enough for the given loading. It is really a fantastic piece of software.
Anyway, I wanted to check the deflection on the rack, and I'm happy to say that deflection at it's greatest is barely over 1/8 of an inch. Given the span and the lightness of material, I am quite pleased. Below you'll see an extremely exaggerated deformation, it has been scaled up about 40 times, so that you can see where the greatest deflection is taking place.
I'll be doing this analysis on the other 2 racks to ensure they are robust enough to support the weight of the wheel/tire combinations.

I'm like #2. Functional and beautiful.

I like them all, and I'd buy one at the right price too. #2 is my fav, not sure how #3 stands up.

I have completed another FEA, this time on rack design #2. Again it looks like we are well within the weight of wheels/tires as deflection is very low at .0175" max. Things are looking good.
