Are wheel Adapters the answer?

[BluewaterFX]

I got a pretty good deal on a set of wheels/tires from a buddy. He needed some quick cash and I'm ready to get the factory wheels and 31" BFG A/Ts off my 82 k5.
I assumed they would bolt right on (came off of an 1989 chevy, 6x5.5) but it seems the studs on my blazer are a little bit short (seem only an inch or so so stud), only 3-4 threads sticking out once the wheels are fitted on and its an 82, has the 7/16" studs where as the truck they came off of had 14mm studs so I couldn't use/test the lugnuts that came with the wheels.
Would buying 6x5.5 wheel adapter plates with 14mm studs (1.5") allow them to bolt right up (And fit my 6x5.5, 7/16 hubs?)
Besides 1.5" of spacing, is there any downside to this?

If a stud is too short in an aluminum wheel, i'm wiling to bet it would be too short for a spacer. Myself as well as most others will tell you to get longer studs, and while you're at it, upgrade to a 1/2" stud.

I'll give my standard reply....take the wheeks to Discount Tire and tell them what you are puting them on. They can probably sell you a set of lug nuts that will fit. Or at least tell you what you need to make them fit.


How about a pic of the wheels?

Or maybe not use the wheels, stick with your old ones. IIRC, the IFS rigs had more backspacing, i.e. deeper wheels. The tires will stick out more as it is, and adding a spacer will just make it worse. You'll increase your scrub radius and wear out those new tires awful fast ... and that noise you'll hear is your balljoints screaming in agony.

Yeah, longer studs would be a start... but do measure the wheels for offset/backspacing before you throw $$ at it.

putting ifs wheels on a solid axle truck would require spacers, not abhor them, correct? I made the assumption that he was talking about the correct rim. But purely in response to the stud issue, longer studs are the way to go. If there are other fitment problems, that's a whole other bag of cats.

And more backspacing means shallower wheels if you're looking at the front face of the wheels, though you could look at it either way

I always get backspacing and offset confused

it happens to the best of us, too many people interchange the terms too frequently.

Also, we need pictures!

What kind of wheels and what style of lug nuts came with them? Do the lug nuts have washers?

Appreciate the input folks, think they're a 30 offset. Definitely went in a bit too deep for my taste, which is another reason I considered spacers/adapters. They're Platinum Flair wheels, 20x9 (I know, I know, 20s) they came with a new set of 33x12.50r20 nitto mud grapplers with 150 miles or so on'em and I have a set of baja mtzs in 35x12.50r20 sitting in my garage that came off my old duramax. If I didn't have the mtzs for a 20" wheel I wouldn't of bothered, Im not a huge fan of large wheels on smaller tires but, for 350 bucks, I couldn't say no.

The lugs don't have washers and are for 14mm studs.

Need to make a few more posts to post pictures it seems
