17” Wheel and Tire fitment question

Holy Jesus those are pricy!

The 2 piece designs are fairly easy to spot at the seam between the center section and the wheel hoop. Much more size and backspacing availability too. 3 piece designs get even more outragous in price.. but there is nothing "cast" about them as metallurgy and heat treats allow for much superior limits.

I seriously wish there were more makers getting into the carbon fiber wheels. The more companies that invest in the tooling the cheaper they will become. Then there's the 3D printing process using sintered and kilned metals. If Konigsigg can make a varaible rate 3D printed turbo out of stainless and magnesium to stand up to near 1,400 horsepower?.. then a thicker wheel should be a piece of cake. Sky's the limit on more intricate wheel designs there too. Not that these damned things aren't already hard enough to clean every nook and cranny as it is. lol

 

The Circle Racing wheels are 2-piece and are polished. Those machined ones look good too.
Do they offer custom back-spacing?

 

If you're asking me ...US wheel
Magnum - GM/Ford/Mopar (Series 527)
in ford/mopar lug patterns they're

17x8 - 4 1/2 & 17x9 - 5 1/8. So I guess that's just the most common ....
