So this morning before I started work I tried ti rush and swap my BFG's AT for my new (used) Mudders. I got them from a club member who didn't need tham anymore. 45 minutes later I was finished and tried to take the K5 for a test drive. Grinding and wobbling from the front end, not 20 feet into the test drive. It seems that the mudders are mounted on 15x8 rims. I did not know this. They came off a later model Chevy and we both thought they would bolt on without any issues. Now the calipers are rubbing on the inner rim. You learn some thing new every time I mess with my truck.
 
Not to be a jerk, but have you typed all of your 1,400+ posts like that? Is there a reason you do that? It is akward to read.

As for your post, do you have 3/4 ton, or one ton axles? I am not quite sure what you are saying.

wheels

I like this type better than the default one, never had anyone complain before. Sorry.

I didn't know wheels for 1/2 ton axles came in different sizes. The mudder rims, I'm told are 15x8. The ones with the At mounted didn't rub, so I think they are 15x10.
 
So you do have stock half ton axles yet? There are hundreds of different sizes of wheels available to fit a half ton Chevrolet.

I do not have a problem reading the font you use, looks betta than those who cannot spell . ;)


Anyways. the width of the rim could be 15x10 or 15x8, doesnt matter as much as the offset. If your offset is where there is more rim under the vehicle, you could rub on the calipers. this means you would need spacers. not sure how much, but it all depends. Some say spacers are not safe. Now if your rim sticks more out toward the outside, that would make it less chance to rub the caliper.

I reread his original post, and he did say they were off a later model. Would it be a 2wd rim? I don't think many of the newer pickups used a 15" rim, besides the 2wd's.

I am pretty sure all 2wd's are 5 lug , but not positive.
Possibly the later models have a different offset, which goes back to what I posted :)

Yeah, the 2wd's use to be 5 lug, but I think they are 6 lug now. I doubt they are still using 15" rims though.

The newer pickups do a have a different offset, but I don't think any of the 4x4's ever used a 15" rim.

rims

I don't know what year my buddy's truck is, it's later than my 89 K5, it's IFS so it's later than 1991. I think I have to swap back and buy some 15x10 wheels, I don't want to start messing with spacers. The ones that don't fit are the black daytona style found on LMC right next to the alumninum whhel on the BFGs AT I was replacing.
 
Swap again!

I just spent my lunch time swapping the tire again. It seems like the rims were rubbing the Tie rod ends on both sides. Thankfully I only moved the truck several feet as it was. I shaved off the tire weights and the surface of the tie rods.

It's not the width of the wheel that is causing this. It is the back spacing (the measurement from the mounting surface to the inner edge.) Most of us run wheels between 2.5-4.5 inches of backspacing. Late models have more backspacing around 5.5 if I remember right.

Yup^^

I own both types, and you cannot use your stock IFS-truck rims as rollers to move your 1/2 tons from your K5 into the backyard. They will just bind up if you can even get them on.

IFS trucks use around 5.5" backspacing stock like MTBLAZER said. I have no clue what stock is for the straight-axle trucks, but it's definitely less than 5.5". I don't think the 900-series 4x4s ever came with 15"s (both of mine came with 16"s), but you can definitely put them on there (maybe that's what the seller had done).

That's not completely true. It depends upon the width of the rim. I ran 16" steel wheels from a 1998 K2500 on my 1975 K20, and on my 1988 V10 (with the 1975 K20 axles). Here is a pic. The newer trucks do use more backspacing, and that is the problem the original post is experiencing.

Ah that is true. I have my snow tires on those rims (salt destroys alloy rims). I was referring to my alloy rims, which are always more prone to fitment issues.

As I wrote, if you have too much backspacing no matter what the width is, they will rub somewhere.
 
ant temp fixs?

I have the same issue on my truck. I was gonna order spacers for the back to match the width of the front but I wanna get the rubbin issue solved soon. Ive got the steering box frame weld in kit from ORD and the brace. Ill try to get these on within the next couple weeks. But is there a way to fix the rubbing issue? very thin wheel spacers for the FRONT or anything???? I wish MT had a trade in deal or something. Id like to stick with the same wheels but Im sure its a backspacing issue.
 
IMO you could use washers as temp spacers but wouldn't drive very far. I've seen the guys at the tire shop do this. But ONLY temp.
 
do the rims look like these?? If so backspacing is definately your problem. I hate that the older trucks tierods are so close to the wheels. I've took weights off myself this way
