Hi, all. I have a 1999 2500 that I am trying to fit 16" aluminum wheels on. The steels are real close to the drum fins and the extra meat of aluminum won't let them clear. I got a sweet deal on a mystery brand wheel (mystery because they're the only ones Ive ever seen and can't identify them) so I have to make them fit.

I understand that 2000 to 2002 had factory aluminum wheels so are they thinner than my 99 or have no fins? Will the newer drums fit my truck?
I sat a wheel up and it almost fits so I thought about adding 1/4" spacers to the back wheels. Yeah, I know about the naysaying but I'm not concerned with 1/4's on the back. I'm also not interested in turning the drums down.

I am more than happy to add any info I missed and thank you in advance.
Here is a pic of the wheels. Anyone know what they are?

they look to be old american racing wheels. I don't quiet understand what you mean by not fitting, will they slide onto the drums? are they not fitting the wheel studs?

 

The inside diameter of the aluminum wheels are smaller than the outside diameter of the drum fins.

 

hmmmm never heard of this problem with 16 wheels, to my knowledge the don't make but one size of the rotor and it would be a heck of a thick wheel not to fit and be a 16" iv got a set of factory 16' aluminum and steelies for my trucks and have no problem fitting either

 

thats cuz those 2500 axles call for 16.5" or above rims i do believe.

 

duh i missed that part yeah you have a bigger drums 16's wont fit to my knowledge prob a dana 60 at minimum so it'll be 16.5

 

There are the letters CPC and the numbers 171 on the backside of the wheel. I called a company called CPC Wheels Corp and they said it could be a prototype or custom order from years age but the guy did not recognize it. I really thought it was an American Eagle or Ultra wheel because of the center cap but I'm not having any luck.

 

Yeah, my 16" factory steel wheels are real close to the fins and I don't have anything to compare to other years. I thought I read somewhere on here that some other years used smooth drums?
