Your right, mine are perfect, any less they would rub the lip on the bed side, any more and they might pose a problem with tire rub on the leafsprings.
Here is how i look at the whole situation, these are AMERICAN made wheels, quality is great, and price cant be beat. I bought these knowing i would need a spacer to make them fit on the front, but once you see a set in person, you will want a set.

O.K... i measured the rear wheel track width on the blazer and it is exactly 73.5 " outside sidewall to sidewall... hope this helps a bit

*mrhino* · 01-27-2010, 08:37 AM

LUV2XCLR8, love your build looks great, Im doing mine almost the same, I was wondering what size tires you are running on the front. as you can see in the pic I dont have any. cant nail it down to one size. thanks

**nlped** · 01-27-2010, 08:37 AM

The 22" version is in the primary warehouse, but won't start shipping until Feb.

**lolife99** · 01-27-2010, 03:46 PM

Ok,... a little update from me.
I wanted to post pics of my 338's mounted.

I hammered the dust cap flat, just in case it hit.
(now I don't think I would have had to).
The clips on the plastic Boss wheel center cap still needed a sliight trim.
The picture shows all of them trimmed except one.
(To show how little needs to be removed)

Everything fit fine after that.
I did put a small dab of silcone on each clip, just for the heck of it.
All of this trouble seems worth it (to me) to get cheap wheels,... but it's far from a "bolt on" wheel.

Another issue I recently found,... is the recessed holes for the lug nuts are really small.
They may be fine for a 7/16" lug nut,... but the 1/2" lug nuts required for our trucks,... seem to make it really tight getting a socket inside the hole.
I used a (3/8 drive) 13/16" socket and it was still hard to get the lugs inside the recessed holes.

zammer · 01-27-2010, 11:44 PM

LoLife99... looks pretty sweet.... Man i love these wheels..

Mrhino... My post #526 on the 338 wheels/tires I went with this size tires:

245/40-20 Falken FK 452 HP _ Front
275/35-20 Falken FK 452 HP _ Rear

They have a very close Diameter... The 275 wide tire is pretty sick.

hope this helps

Ronm909 · 01-28-2010, 12:08 AM

love these wheels so worth a little extra work.
Can anyone please measure total outside width of thier rear wheels, I think I got too big of a real tire. 315/35/20...12" wide. worried it will not tuck if laid out??? I got 73" total width. is that cool?

Ronm909,... the width will depend on which rearend you have.
67-70?
71-72?
73-87?

I think those 315's look perfect on there.
I'm running a 295/40-20 on the rear.

Ronm909 · 01-28-2010, 12:22 AM

87 10 bolt from a suburban

I wish i could fit a 315, may be able to get a 305, but will upgrade to a 295 when time comes.

Thanks Kris it looks like your about 27 1/2 inches tall. Im using 18's at 27" inches tall on the rear, the fronts I'm undecided looking at 245/45/18

skoffice · 02-09-2010, 10:42 PM

Looks like I'm in for a real treat trying to get a set of these wheels to work. I had my eye on them for a few months now and someone in another thread led me here. I'd say they are worth the effort but WHY haven't they made a revision to this wheel??? They would certainly sell a LOT more of them. I wonder if all their wheels for 5 on 5 have the same issue? Because I had also considered the 336's...

72BlckButy · 01-28-2010, 09:10 AM

Lookin' good lolife99...

Forgot to tell you thanks for the updated pics you sent this weekend; the tires fit well on the rims.

69gmcshorty · 01-29-2010, 04:09 AM

on my 69' 12 bolt truck rearend using percy's wheelrite tool i am not able to run 295's. i was wanting to put on 295/40/20 with 245/40/20 fronts. i am a leaf spring rear though if that plays much in widths? i will settle for 275/40/20 for now.

fast 95 · 01-29-2010, 10:22 AM

I'm running a 275-40-20" on the rear, it fits the wheel but looks a little stretched to me.

Make sure you post up some pics when you get them on. I was thinking about getting those but went with the Boss 338s because of the BS for the rear.

If you do, please do so in a new thread. Thanks!

k5hart · 02-02-2010, 09:10 PM

Fast95 what's the specs on your wheels? I've got a '91 and I've been looking at this same wheel. Your look like they fit really well.

fast 95 · 02-03-2010, 04:29 PM

20x8.5 fronts with 5.25 bs, 275-40-20" tires and 20x10 rears with 6.225 bs, 275-40-20" tires in rear. I'll upgrade to a 295-40 or a 305-35 tires for the rears just for a better fit.

72BlckButy · 02-06-2010, 12:57 AM

Saw this one on Ebay running the 338's... (not 56k friendly)
