Never factory in that width.
How wide do you believe those rallies are?

@Buicknut 5 lug rally wheels were available first for 2 wheel drive trucks. The 6 lug 4WD rally wheels a few years later 1975 or '76.

Some 1980's 4WD Suburbans had wider rallies, for sure 1985.

I believe most of the 6-lug rallies were 8" wide, with some being 7" wide. I personally don't remember seeing a 7" myself and I don't know what they came on.

6 lug rallies available from GM in 3 different widths. Don't know them all from memory but definitely 3 sizes.

I thought they were an aftermarket 10s. The smooth band after the trim ring looks wide. Here's some 15x8s The ones in his Pic look deeper to me.

Maybe 6", 7" and 8" from the factory? I know the 5 lug ones were available in 15x8 cause we had em on the back of the '84 Burb, with mudgrips on them. The early "star" style OBS alloys we had on the front. Dad liked that wheel and wanted to run them on all 4 corners, but they didn't have the weight rating to do so. And this was our primary swap meet truck, and also this was in the late 80s/early 90s before anyone was repopping those wheels.
I had a set of the 6 lug Rallyes for an older truck, that I'm pretty sure were at least 7" wide, and might have been 8". Don't have them anymore....

There are several different trim rings that will fit these wheels. Dad liked the more square edges with just a little bit of rounding, and he found some for the '79 and '84 Burbs. I wanna say that's what the original style was?? But there are other styles with the wider, more sloped profile. Maybe that's what is more "correct"?

Keith would know better what they came on but I've always been under the impression that trucks usually got x8s, some got the 7s and vans usually got either 6 or 7" wide ones. IIRC, the rally debuted on the Gentleman Jim in '75

Yeah if you are talking 5-lug, they came in many widths and backspacing depending on application. Iirc, even Caprice cop cars got their own dedicated version of the wheel.
