15x8 DON'T FIT? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

69BUCKET · 11-08-2020, 01:37 PM

Just got some 15x8 rally wheels and they don't clear the caliper on my 72...?

Sorry, pic won't load...is it a van wheel maybe?...

jimijam00 · 11-08-2020, 02:05 PM

not oem brakes?

69BUCKET · 11-08-2020, 03:55 PM

I believe they are oem...

**leddzepp** · 11-08-2020, 04:28 PM

Looks like a 7” or maybe 6.5” wheel. No matter, should still clear calipers. 5 lug vans also had disc brakes. I’m guessing you have dropped spindles?

69BUCKET · 11-08-2020, 05:23 PM

They are 8"...that's why i stumped. Its all stock...no drop spindles, no aftermarket brakes.

03BlkZ · 11-08-2020, 05:51 PM

My 15x8 fit my 70 but I have CPP brake kit from summit with 2.5 drop spindle. Those don't look deep enough to be 8 inch. I guess the picture can be deceiving.

His aren’t 8 inch.
Maybe 8 inches from wheel lip to wheel lip.
Subtract 1 inch from that gives 7 inches.
Rims are measured tire bead to tire bead.

this is what i thought...is there another brake disc option that would not let these wheels fit?...

68Gold/white · 11-08-2020, 07:25 PM

Picture of caliper/spindle assy might help...

69BUCKET · 11-08-2020, 09:29 PM

I'll get SOME PICS of caliper TOMORROW. PROBABLY GOING TO BE selling THESE SINCE THEY DONT fit. Decent TIRES ON too... 235/75...

**Already Gone** · 11-08-2020, 10:35 PM

Maybe at sometime someone when doing a brake job put different/bigger callers on the truckand were okay with the stock rims.

gmc684x4 · 11-08-2020, 11:44 PM

Could those be of something like an astro van with a little too much backspacing ?

Early wheels have this fitment issue as well usually with a wider inner bulge that digs into the caliper from a drum drum truck

I have factory 8" rally's and was planning on drop spindles because i am currently running factory cut springs. The A arm angle is pretty bad and not sure if the alignment shop can get the front end lined up. I don't want to go with a different wheel set up. So with 15" wheels, I cant run drop spindles? Thanks in advance, Carl

**leddzepp** · 11-09-2020, 11:43 AM

You can run dropped spindles, just have to do a little trimming on the lower control arm. Member lowlife99 has a good write up and pictures illustrating how/where to do this. Alignment is not an issue, I’ve run them on several trucks.

The alignment i was referring to was my current set up with cut springs and the extreme A arm angle. i should have clarified that in my post. Sorry about that.
Thanks, I'll see if i can find his write up, Carl

kaycee · 11-09-2020, 03:36 PM

Do you know the back spacing on them ,Dont look like they are as deep as mine 4 1/2" I belive is the BS. Ill have to go check later Soo looks like mine are 4" maybe 4 1/4" hard to tell with tire on

**chevy71super** · 11-09-2020, 07:43 PM

Here is likely a dumb question. Is the lug pattern 5 x 5 or 5 x 4.75? Not sure it matters . . .

jimijam00 · 11-09-2020, 08:20 PM

So the backspacing is the reason they are hitting the calipers?

Thanks for the link! Carl

**special-K** · 11-10-2020, 06:40 AM

This totally baffles me because truck rallyes only came on trucks with disc brakes.

X2, strange.......

**Already Gone** · 11-10-2020, 10:55 AM

i have a 1999 OBS Tahoe 4 x 2 with the Police Package. Now I've seen lots of OBS trucks with the 80's rallys on them and they fit and work great. I tried to put a set on my Tahoe and they wouldnt clear the caliper. I didn't measure the calipers but sure they are bigger than on a stock non-police OBS truck or Tahoe. Thats why I mentioned earlier in this post that maybe the calipers were changed at some time and bigger ones and maybe not from a 71-72 C10 were used.

**chevy71super** · 11-10-2020, 01:55 PM

Here is a similar rim Coker Tire sells. Looks the same from the front. Description states it fits 71 to 87. Maybe a picture of the back side of your rim will yield some clues? Also a picture of the brake caliper?
