This is pretty much off-topic, but is there a thread anywhere that lists the different rear-end widths for the different years? I've searched the forums and Google with no success. Sure would be nice to have readily available.

Going off the top of my head. I'm running a 71-72 rear. Back plate to plate is 57in if my poor memory serves correct.

Yea 6 lug. I can't win...

Wildstreak · 03-23-2010, 12:59 PM

what tire size is everyone goin to run on their rear rims?

Security guy · 03-23-2010, 01:13 PM

I just had to get in on this thread. I can tell its going to be another 20 page thread. I'm going to try and order a set on thursday. I was trying to hold out until we could see a truck with the new wheels on. Does any one know for sure if there will be another order placed next week?

When I get my set I plan on running 245/40/18's on front and 295/35/18's on the rear. I would probly run about the same with the 20's aswell.

Those will be short. I would recommend a 245-45-18 (26" tall) & 295-40-20 (29" tall).

What do you suggest on a 20x8.5 up front?

Both are about the same height and 295/35/18 is 26 iches tall and 245/40/18 is about 25.75 inches tall. I'm going to run 18's all the way around.

AusTx68 · 03-23-2010, 02:29 PM

I sure hope someone posts some pics once they get their wheels. I'm curious how the 20x10s look with an adapter in place.

Tow Me · 03-23-2010, 03:25 PM

I might be jumping in on this... I will talk to my dad too since he wants a set. I'll get back before the deadline!

Leviticus · 03-23-2010, 03:04 PM

Well...got some bad news boys. The new revised fronts don't fit. Looks like it is the same issue as before, it won't seat all the way down onto the rotor, looks like it is tight at the front of the hub bore like before.

And just to sweeten the deal

the rear 20x10 will require a spacer to fit. I didn't have the tires on but it looks like (judging by sight) about a 1/4 to 1/2" spacer to not rub on the inside of the fender well.

Well, we are dealing with Boss here, what did we expect

You sure you got the -3 revision? Doesn't sound like it. Do you have a caliper (measuring device, not the brake component) to measure the bore? Please post some pics, including one of the label on the box.

Hey, now. You can't blame them for your failure to consider backspacing before ordering. As I've said before, the purpose of the revision was to correct the front hub fitment issue, not to change the backspacing (which is unchanged and which you should have recognized as an issue before making your purchase).

Leviticus · 03-23-2010, 03:27 PM

Hey brossow,

don't get all pissy on me, I'm not blaming them for the BS, I had expected I might need a spacer on the rear, no biggie.

But I am blaming them for a revised wheel that does not fit. Box said right on it 3AA. There is a picture of the label in a thread I posted this morning. I'll take some pics of the figment issue when I get home, at the tire store right now.

I might get away with a little grinding on the tip of the hub.

Sure looked like you were blaming them. You said, "And just to sweeten the deal the rear 20x10 will require a spacer to fit. [...] Well, we are dealing with Boss here, what did we expect." I don't know how else to interpret that statement other than you blaming Boss. But I've been wrong before. *shrug*

Don't want to argue; just surprised by all the people willing to lay out a LOT of money without even knowing what it is they actually need vs. what they'd be getting. Not specifically including you among them -- just making a general observation.

Brent,

Not trying to fight with ya

, I knew the 20x10 was a toss up on fitment, I was the one over in the other Boss thread saying I will see if it fits or not. I'm not just some idiot shelling out cash thinking they will fit, I was willing to take the risk to run the 10"s in the back.

The fronts on the other hand are somewhat frustrating, but I was expecting the old version when I ordered them so I am just truckin on

Anyways, I'll let you guys know what I can work out on them, I have some 1/4" spacers for the rear I am going to try to see if they get me clear.

And we will see how much material I am going to have to take off the front hub.

I'll keep you all posted, on a good note,the tires look sweeet on the wheels!

Here's a direct link to the thread mentioned above if anyone wants to follow along over there. Not a good sign....

Wildstreak · 03-23-2010, 03:37 PM

so does this mean the re-tooled rims dont fit either?

72mistressc10 · 03-23-2010, 03:38 PM

x2 ????

Wildstreak · 03-23-2010, 03:45 PM

@Leviticus
I looked at your thread and the part number on your box is for 20x10 even tho it says its for 20x8.5 on your box. I kinda find that odd....

Wildstreak · 03-23-2010, 03:48 PM

on the boss website I can even see A 20x8.5 with 5 on 5. what is the correct bolt pattern for a 72?

No, that's correct. The part number for a 20x10 in grey is 3387-2050. His box clearly says 3387-2850.

They don't list it there for some reason. The regional manager I've spoken to about these wheels doesn't know why they're not listed in the spec sheet, because they're definitely available and in their system.

I know that, but look at the rim size on his box it says 20x8.5.......

part number 3387-2050 is for the 20x10

Original post shows this also.

72mistressc10 · 03-23-2010, 03:52 PM

I believe the new hub bore was suppose to be 94.62mm=3.725, right?
