Ok, so I'm going with 20" diablo delta force rims with a 5x114.3 bolt pattern. I'm going to get metal hubcentric rings, probably from http://www.1010tires.com/hubrings.asp#Note1 but I have NO CLUE WHAT ONES TO GET!?!?! There are so many choices on that site and I'm not sure how to figure out what the inside and outside diameters are. What ones will fit on a CTS? Any help is greatly appreciated! :bouncy:

Different rims need different rings.

Well, not exactly true. The bolt pattern of the Cadillac stays the same. The wheel's pattern of course should match.


Here's how to get the measurement for the rings. Which will vary slightly between wheel manufacturers. The inner diameter should be the same across the board. The outer diameter depends on the wheel itself. Won't be a great difference.

And here's the definition of the bolt pattern measurement.

OMG those rings are TWICE the amount as Discount Tire. $40 vs $20.:eek:

As I recall, our cars are 70.5mm (or very close to that) hub diameter. So the rings will need an outer diameter of whatever the center hole of the wheel is, and an I.D. of 70.5mm. They simply snap into the center hole of the wheel.

I had to rotate my tires today so while they were off I micrometered the hub. After I wiped off a little surface rust, it measured 2.765 inches. If you allow .003 inches for clearance, that means the inner ring diameter should be 2.768 inches or 70.3 mm... seems to me I read that somewhere too but I can't seem to find it.

Oh, and for the record, a stock 16 inch wheel with a nearly new stock tire (Goodyear RSA) weighs a little under 41 lbs. I wonder what an after-market 18 inch wheel with a 225/45 tire on it weighs. I'll bet it's more like 50 lbs. Since I'm in the market, I guess I'll find out.

Ciao

Cool, let us know how it goes Struditor. It would be nice to get type of rim and tire combination. Type of alloy used. Cast, forged or 3 piece.
