wheel ?

DO YOU HAV ANY IDE WHAT SORT OF BACK SPACING WOULD YOU SAY WOULD CLEAR. CAUSE I READ ON HEAR SOME WHERE I CANT FIND IT NOW BUT SOMEBODY IS RUNNING 15x8 ROCK CRAWLERS I WOULD LIKE TO KNOW SO WHEN I ORDER THEM TOMARROW I DONT GET THE WRONG ONES PLEASE THANK YOU FOR YOUR HELP

O.K., you have to follow along here.

Joe Black is running 15x7 wheels with an offset of +40mm.
About 2mm of the inside edge of the rim contacted the upper control arms. So...
These wheels (15x7) equal an offset of 5.07".
Therefore, we can safely assume (?) that the upper control arm lies 5.00" inboard of the mounting pad for the wheel. (that 2mm of contact = 0.08").
Still following me...?

You need to find the correct backspacing for an 8" wide wheel.
Well, 1/2 of your rim width = 4.0" If you find a wheel with 4.0" of backspacing, it WILL NOT hit your upper control arms BUT , it will cause problems with the rubbing of fenders and such -many members have had troubles with +0 wheels.
So...
You need to split the difference. Not too much rim inside, and not too much rim outside.

Somewhere between a backspacing of 4 and 5 inches will be best. I'd get as close to 5" as possible, without actually hitting 5". This will keep the wheels tucked in, fighting the dreaded rub AND it will keep the wheels out far enough that your small diameter rims won't rub your suspension bits.

Make sense..?
Go for the 4.75" wheels.
This is the same as a 15x8 wheel with a +20mm offset. This has been proven to fit the VX as long as you don't get too crazy with the tire selection.

damn how much offroading can you do in Key West before you need positive bouyancy? :P

Hey mbeach, I've been reading along here since you seem to know what you are talking about and I am also in the market for rims. I know I could machine anything I buy to fit the large bore, so taking that into consideration I was thinking about the American Racing Chamber rims again.

http://www.americanracing.com/wheels...lloy&section=S

But, considering everything you have stated here it looks like none of these rims will work no matter what, since the 16" rims with a 6x5.5 bolt pattern have a 0 offset and only 4 1/2 on the backside. All the offsets on their chart are negative offsets or 0 offset. There is only one listed with a positive offset.

Am I correct? I really want to get these rims or at least know there is no way to make them work so I can stop dreaming about them. Sorry, I absoluted NOT mathmatically inclined and all of these numbers give me a headache.

Thanks - Bart

I really oversimplified my earlier explaination -it's kinda difficult when dealing with offsets/backspacing/suspension bits/fenders. You could go nuts trying to figure it all out.

I learned quite a bit trying to stuff some 17x9 wheels into a car after I had converted it to coilovers. Nothing seemed to fit, because the coils were rubbing the tires. I had all kinds of cardboard templates out in the driveway trying to make things fit. It was a painful learning process, and it actually cost me a set of nice wheels.

Here's a really good site explaining some of the finer points of wheel selection:

As for those Chamber wheels, they really are sweet (especially in black), but it looks like none of them will work. Wait for the Colorado/Canyon pickups to gain popularity -they have a close fitment to us.

Yes, I AM GOING NUTS!!! For now, I will probably just go with Rock Crawlers or the 16x7 Trooper wheels which I am about 99% sure will fit with zero problems according to everything everyone has said on the board.

Thanks for the link - I will check it out. Slowly but surely, the reading and repetition will sink in.
