Pic of the correct 15 x 8 truck rally trim ring. Trim ring will have a 3/8'' flat around the outer edge and gentle curve in towards the center.

Might just be my old eyeballs but they don’t look like 8 inch wides.

My rallys have Corvette trim rings on them and I like that look better. They are deeper and cover more of the wheel dish.

While we are on the subject of rim widths my picture shows the correct way to measure rim width. A lot of people say I have 15 x 8 rallys but measure the rims outside measurement. You did say you were looking for education.

If those are Corvette wheels the bolt pattern will be 4 3/4 X5, our trucks (5 Lug) are 5X5 bolt pattern. Unless you have changed over to the car pattern.

Any 15" beauty ring with fit either rallye or steelie, except maybe the 3" on stock width (6") wheels. I know the GM "correct" rings are 3", but I sure do prefer the narrow (2"?) ones that let the wheel be seen, still serve to add the "trim" look desired, and actually fit to the contours of the wheel. I have this picture of a big/little set I did with incorrect rings and later truck centers, which I also think look better, that show the 8" wide... being the wider pair. Everything about this set id incorrect, yet 100% GM truck. Just my own preference for all but 100% factory restoration. "That's the touch I like" :cool: BTW, I know a good song by that name. Going to the "Nudder Music" thread to post it while it's on my mind. Any other unrelated topics you'd like to here about before I go? :lol:

Wider (top) are absolutely 8" and I believe the rings are same as what you have on yours in the pictures:

90's cop cars came with 5x5 rallys. May have been 7 inch wide tho. I just pulled the center caps off one in a junk yard the other day.
