7" wheels vs 8" - The 1947 - Present Chevrolet & GMC Truck Message Board Network

RandyP · 08-27-2010, 12:48 PM

What is the easiest way to visibly tell a 7" rally from an 8" rally? Do they have a different vent pattern or anything? I'm going to look at some stuff tomorrow and he thinks he has some 7" wheels, but they all have tires on them etc, so how in the world do you really know without laying a tape across the rim?

I'll have to take pics, but there is an extra inch of space just to the outside if the center piece. Kinda hard to explain but easy to see once you figure out what I'm talking about

RandyP · 08-27-2010, 01:40 PM

Ok, you talking about either of these areas in white or yellow?

Prerunner1982 · 08-27-2010, 01:40 PM

It is also stamped on the back side of the wheel if you have access to it..

joe231 · 08-27-2010, 01:43 PM

The area in white
Here is a 7"

Go go gadget attach photo!

joe231 · 08-27-2010, 02:40 PM

Dude, give me a break
I'm on my phone having to upload to photobucket then to the forum

RandyP · 08-27-2010, 03:12 PM

Evil phone web! The internet has been acting up at our house, every time it goes down the wife grabs her iphone and "keeps on trucking". I call her addicted, she calls me fat.

Wouldn't it be easier to just use the sites attachment thingy?

Anyways, thank you very much for the photo, I know exactly what to look for now. I think most of his wheels he has for sale are still on the trucks, but I'll try to double check the backside for the stamp if possible.

Good info!

joe231 · 08-27-2010, 03:55 PM

I wish I could attach to the site but my phone won't let me

I agree the area in white is wider on an 8" rim. The blue rim in the picture looks more like a 6.5" rally from a van...but that is just from what I can see...

RandyP · 08-27-2010, 04:59 PM

The more I search, I do see that there are 15x8, 15x7 and 15x6.5 rallies. I think I'd actually have better luck with a set of the 15x6.5's.

*Off to the bat cave!

those look amazing

joe231 · 08-27-2010, 05:21 PM

I thought the 6.5's were just a myth.....I'll have to measure the blue one.

I have a 6.5 and 2 8's at the house. I will try to get a picture of them....I wish I had a 7 also for the shot....

RandyP · 08-27-2010, 05:36 PM

The 6.5's are Gvan only. Trucks had a 15x6 option, but they are a totally different looking steel wheel, not a rally.

About the best I can do for a picture, you can see the different style wheels on car-part.com

My 15x7 truck rallys also have the 2 lips... as mentioned the inner most lip is smaller.
