1.25 or 1.5 Wheel Spacers

I know this topic has been covered many times and Iím sorry for the inevitable repost but the search didn't yield the results I was looking for. I am about to get some 305/70/16 (32.8 x12.01x16 according to the conversion) to go on my MOAB wheels in the very near future. I know I am going to need some wheel spacers so I donít have any rubbing issues. My question is, do I need 1.25 or 1.5 inch wheel spacers? Thanks for the help

1.25 is plenty. I ran 32's on my stock wheels without spacers and had no rubbing issues at all.

I'm running 1.25 with 33x12.50's on stock wheels and have very little rubbing.

What width are the tires, and are they on the MOAB wheels?

What is the back spacing on the stock wheels?

I put 1.5" spacers on with my Ravines and still rub my control arms a little at full turn with 35"s.

Also with the 1.5" spacers I had to put on longer wheel studs in the D44 shafts. There wasn't enough engagement of the threads with the stock ones.

Most stock wheels have 5.5" of backspacing with the only exception being Moabs (5") and Gamblers (5.25").

You could run up to 4.75" of backspacing and have enough room for 12" wide tires. You would rub slightly when turning full lock. If your axle is not centered, the rubbing will be worse in one direction.

The size of the side lugs on the tire is a factor in how much it will rub.

What type of lower control arms is another factor (many aftermarket arms give you a little more tire clearance).

If you want full turning radius lock to lock, I think 1" or 1.25" should be plenty for you.

The tires were 32x11.50. My backspacing was 5.5". Yours are 5.0" so you already have an extra .5". Either will work, id stick to the 1.25"s though.
