Wheel Bolt Pattern?

[uncletiffy]

1979 Cherokee Chief.

what is my wheel bolt pattern?

6 x 4 1/2
6 x 5 1/2
6 x 6 1/2 ?

Thanks.

[uncletiffy]

oops, sorry I already asked this question.

Its 6 x 5 1/2.

You should note that some newer style wheels have a center hole that is too small. As I recall we need a 3" center hole. But double check that.

These are what I am looking at.

Not sure how the 3.75 backspace will work?

the center hole is 4.28 "

I like the first one best as it is nice and plain and the fact that its matte black makes it easy to maintain.

OK, the wheels center hole is

Center Bore Diameter (in):4.280 in.

Center Bore Diameter (mm):108.71mm

Will my front axle fit through?

I was off a bit, 3 1/8" looks like the hub diameter. The 4.28" bore is because those wheels must be used on axles with a larger bore (Like a D44HD or D60). They will work, but won't be hub centric. So when tightening the lug nuts, make sure you do them evenly as they are centering the wheel.

How crucial is a snug hub fitting in the center bore?

I'm having these put on by the tire shop as we speak, mounting 33x10.5 KO2s. Same bore size of 4.28

Its not super important. You may get some vibrations, even after balancing and such. If so, there is a place that sells hub centric rings to fill in the gap. Made a huge difference on the steel wheels that I used to have on my JK.

Our old wheels relied on the lug nuts to center on wheel hence the cone shapped. New ones rely on the hub and use flat lug nuts. As long as the new wheels can take the old cone lug nuts it should pull up just fine.

All the D44's in the FSJs are lug centric. Just make sue you snug down the lugs pretty good before you put weight on the tires and you're fine. Torque them to spec after the wheels are on the ground.

Also, I run lug centric wheels on my 2012 JK that came from the factory with hub centric wheels. I do not run a spacer ring. I have no vibration problems at all.

As long as you have either the lugs or the hubs centering the wheel, you should have no problems with vibrations.

What is this place that sells the hub centric rings? I heard that these rings are easily available for aluminum wheels but difficult to source for steel wheels.

Cone lug nuts used and so I'm running "lug centric", new term I learned today.

I have had no problems with vibrations

You just need to know the OD and ID in mm.

I suggest getting plastic ones, not aluminum.
