2007 Ram 1500 4X4

Please recommend me a good set of 1/2" - 1" wheels spacers.
Not one size fits all but proper fit spacers.
Right now my 285/75/17's only clear the upper Control arms by about 1/4"
I am getting ready to get new tires and want to stay same size or slightly bigger.
Can't afford new wheels with better offset right now.

 

Have you already bought wheel spacers?

 

Not yet.
I tried to install a new set of BFG KO2's, (285/75/17) but they hit the UCA.
I need another 1/2" clearance, 1" would be ok.
Also looking at new rims, but most are 9" with -12 off set, this I believe will put my tires
about 2" outside the fender well, don't really want that much sticking out.
Would not mind if they stuck out about 1"

 

The 9 inch rims with -12 offset will have approximately 4" backspacing. What size/backspacing are your stock wheels?

 

9" with -12 offset gives 4.5" back space
My stockers are 8" with +25.4 offset gives 5.5" back space.
So if I calculate correct the a 9" with -12 will put my tires 2" out farther

 

Erm, not according to my math..... Half of 9 is 4.5, 12mm is approximately a half inch.... so, 4" backspacing.

 

Just ran the calc on Custom Offsets web site.
4.53"

 

Real curious how that works..... How can you have a negative offset, yet backspacing is a little over (very little) half the width????? Everything I am reading tells me that can't be right......

Supposedly, Offset is the distance (in mm) of the wheel mounting surface from the wheel centerline. On a 9" wide wheel, the centerline is at 4.5 inches. So if you subtract 12mm (roughly half an inch) from that, how in hades to you get 4.53??????

 

I have no idea, I was just using the Calc's from their sight and a
couple of others and they all say the same numbers.
The Calcs say centerline on a 9" is 5"

Also ran the Calc on my stock 8" wheels that are marked +25.4 offset and calc says 5.5" back space.
I measured them and back space is 5.5"

Wow, am I confused now.

 

You and me both Brother.
