Backspacing ??

In my quest to search for the cause of my vibe(s), I'm looking into the wheels as being a co-conspirator. I'm considering the American racing wheels and they stae that the 15 x 7 has a backspacing of 4". Does this sound right for a zook with 30 X 9.50's? Thanks....
BTW...I have 15 x 7's on it now, but haven't had the chance to measure the backspacing yet.....

All Good Medicine,
Crow

Creator, everything we do leaves a track. May our tracks be ones we would want you to see and others to follow......

Re: Backspacing ??

I was under the impression that 2.5 was the desirable backspacing when using 31 + size tires with the width being about 2" to 3" less than the width of the tire. Jim

Re: Backspacing ??

Stock backspacing is 3.5". A B.S. of 4" would be bad. It would actually pull the tires into the springs more creating a bad tire rubbing situation.

You want to go to 2-2.5" for backspacing if you're looking for a bit more stability and to keep your larger tires off the springs. No "off the shelf" wheels are made with less than a 3.5" B.S. which is why you'll see shops like ours who offer custom backspaced wheels.

Another thing to watch out for is that some wheel suppliers don't realize that the samurai hub is actually larger than many other hubs on the market so the center hole can be important. Too small a center hole, and your new wheels don't fit.

You can check out our selection of custom backspaced wheels at http://www.rocky-road.com/wheels.html

Re: Backspacing ??

Crow,

Most of us NE guys are running Willamette custom wheels. Very reasonable prices, excellent quality, sound construction and he'll make them in whatever BS you want. It's a small shop, so it usually takes a week or two, depending on how busy he is. He's been building them since the early 70's.

Most of us run 2", as this is about as far as you can go. Really widens the stance, and adds stability. Makes flat towing interesting though.

Yo... they 're custom wheels too! You can't go into wheel stores and buy less than 3.5" B.S. without special ordering them.

We feel that its not even worth buying a custom wheel unless its at least 2.5" B.S. Most folks go with 2" B.S. though.

We have a selection of wheels as well. We don't tell people what style wheel they must have to get a custom offset. Prices to below $50 too. We also use USWheel. One of the top wheel manufacturers in the U.S., VERY well respected for their quality and consistency.

Re: Backspacing ??

First off have you tired a set of stock rims and tires to see if your problem goes away? I hate to see you buy a set of rims you don't have to.
