I did a search and I see some people are indeed running 15 inch wheels on the rear. I am seeing where some people say the only way for them to fit is to grind on your calipers. The thing is I couldnt find someone who posted the question asking about the same truck as mine so I figure I'll just ask to make sure its clear before I order.

Will a 15 inch wheel fit on the rear of a 04 Silverado RCSB with just the plain jane OEM disk breaks? If not how much rigging is required?

 

As far as know, the smallest rim you can fit on your truck is going to be what ever your spare tire/rim combo is that came factory with the truck....

 

i run a 15 in the rear because im drum

 

must grind for 15's with disk breaks.

 

Dam that sucks, didn't want to have to grind up my caliper.

 

The smallest you can run with disk rear is a 16" rim....I am drum and run a 17" rim.......

 

When you say the smallest you can run, do you mean without grinding?

 

Yes
A 15 will fit your truck, with the right offset, and grinding
