Any way to get 4wd rims to fit on 2wd truck?

[lrizzo2001]

I just purchased 4 used 4wd rims to put on my 2wd 2dr blazer base model, only to find that they obviously won't fit. Is there such a thing as an extender that would allow me to mount these rims on my truck? The local tire place said there's some kind of disk that can be bolted on to the existing posts and then it gives you 5 new posts to mount the rim onto, but he said they don't stay on well, anybody heard of anything like this?

Need to know what years we are talking about...I thought all newer were 5 on 4.75...I believe what you are talking about are wheel adapters...depending on how you drive they can be safe...but will make your wheels stick out further...here is a link to summit racing adapters... http://www.summitracing.com/search/b.../?autoview=SKU

I have a 1999 2wd 2dr base model chevy blazer, and I want to put on wheels/rims that came off another 1999 4wd chevy blazer. The spacer shouldn't make the wheel stick out any more than the current wheel does.

I have to agree with friesza - the spacers will cause the wheels to extend out farther than original . It will increase by the thickness of the installed spacer , actually the increased width of the vehicle will be twice the thickness as there is a spacer on each side of the vehicle . You will need to check closely for wheel clearance not only in the straight ahead position but also when the front wheels are turning side to side .

[lrizzo2001]

but my understanding is that the correct spacer will not make the wheel stick out any more than the original wheel. I'm not looking to put on a wider tire, the tire is the same size as the current tire, in fact I want to put those tires on these rims. So in theory this tire should sit exactly as the current tire does, only the spacer would bridge the 2" gap that would exist, so again, in theory, the front tires should have the same exact range of motion.

Anything placed between the original wheel mounting surface and the wheel will cause the wheel to be moved outward an amount equal to the device thickness . The tire would sit on the wheel rim in the same place but the entire unit ( wheel with tire mounted ) would be moved out farther than it would without the spacer being inserted between the wheel mounting surface and the actual wheel .

why would the spacer move the tire out further if it's only making up the difference in the backspacing? the 4wd rims have a 6" space and the 2wd have 4", wouldn't the hub-centric spacer simply bridge that 2" gap?

You never mentioned the difference in backspacing between the wheels ? If there's 2 " difference and the spacer is 2 " thick , then you're probably right about the wheel ending up in the same place ? It's helpful to have all pertinent information . The center of the wheel would still move out but this would be made up for by the difference in backspacing . So I guess you're kinda right , me as well ?

[lrizzo2001]

ok, so we're both right, and on the same page now.
that being said, do you feel the hug-centric is still a safe option?

He did give pertinent informations if you look at prior posts. If you know anything about these vehicles you'd already know that the backspacing of the rims are different.

I have spacers on a skidsteer and no issues. They are cast iron. But I have seen others use the aluminum ones and same end result. Just check torques on the spacers as specified. Like with anything, once you install new, recheck torque after 50-100 miles. You'll be good.
