What size are stock rally wheels?

I have an R10 with the stock Rally wheels on it. Are they 15x7's or 15x 8's?

They could be either. Trucks came with both sizes. Probably 15x8's since its an '87. Post a couple pics and I am sure we can identify them.

The Rallys are 15X6.5 which is for a van and the trucks came with either a 15X7 or 15X8.

Re: What size are stock rally wheels?

Huh. I thought all the truck rallys (C/K/R/V) were 15x8, and the van rallies were 15x6 or 15x7.

My '87 R10 came with 15x8's, btw.

My van rallies say 15x6.5 on the back, but I didn't try to see the back of the truck ones.

Re: What size are stock rally wheels?

I thought all vans have 15x6.5, early trucks(73-76?) had 15x7, and later trucks{77-87?) had 15x8. Also I thought the transition from 7 to 8 was the same time the center caps changed from bolted in the back side to bolting in the front.

Re: What size are stock rally wheels?

I'm pretty sure mine are 15x7. I'll pull one of the wheels in the morning and make sure.
The center caps bolt from the front.
77 Silverado.

Those look to be 15x8 since that 235 is stretched pretty good.

I was wrong on mine.
They are stamped 15x8 on the back side.
