police / cop wheels center disc size ?

[rustytoolss]

Does anyone know what the center disc outside diameter is for the 15" mopar police wheels ? The part that is welded to the ring/barrel

The standard size I’ve read is 2.81” for all B bodies whether drum or disc.

not the wheel center bore hole....The center part of the police wheel (6 slots/lug stud holes and bore hole) part that is welded to the barrel.

Just a guess but I’d be surprised if it is any different than any other 15” Mopar wheel.

The barrel on cop car wheels are made from thicker gauge steel than the regular wheels. I would expect the center disc OD to be slightly smaller than regular wheels.

I can post measurements tonight or tomorrow.

Thanks, that would help me.

The inside diameter of the barrel is 13.25".
(24.25-11.00=13.25)

Measurements taken on outer side of wheel.

15" x 7" Mopar cop car wheel (15x7JJ). I used to own a retired '88 Plymouth Gran Fury Sheriff's Deparment car.

The center piece is welded to the barrel in four locations. Each weld is approximately 3-1/2 inches long.

I cannot obtain a consistent measurement around the wheel lips because of the forming/fabrication of the barrel, but it appears to be 8 gauge.

The thickness of the center piece lip adjacent to the barrel measures 0.21". This measurement is consistent all the around around the barrel.

Note: This is the backside of the wheel.

Wow Wayne nice job, I hope @rustytoolss got what he needed

They are heavy @davek

Exactly 26.5 pounds for one 15" x 7" JJ cop car wheel.

BTW, the backspace is 4.5 inches.

Thank you so much.
