I just bought some wheels. They are made by Pacer but look identical to the black rockcrawlers. They have the red and blue rings around the wheels and everything. I went up there today and asked the guys what the backspacing was on them and they said 5 inches. Is this too much or dangerous? I'm pretty sure rockcrawler wheels have 4.75. Would another 1/4 inch make that much of a difference?
Thanks!

 

Other than the fact the wheels won't be able to turn, they should work fine.

5 and 4.75 will not work. Count on 4.5" max.

 

I believe you but im curious, why wouldnt it turn?

Im guessing the guy didnt know what he was talking about. Is there any wheel out there with that much backspacing?

 

Certain late model GM models (IIRC) have 5 1/4" of backspacing, but other than that the backspacing that is normally found on IFS rigs is 4 1/2, max 4 3/4". 3 3/4 for solid axle rigs. I think you will find that if those are 5" they won't physically fit your on rig. They will probably hit steering components, and tires would rub on the upper A-arms too... Easy enough to try one on the front and see.

BTW - I ran across this: http://www.usacomp.com/Offset.htm

 

Yeah...thats not good, I've never even heard of a wheel havin that much backspacing.

Well it seems that these did. Darren was right. They got the tires balanced, tried to put them on and they hit my calipers. Im pretty pissed. I told the guy to get me wheels for a 99 4runner, and they dont fit.
