Anyone know what these holes are for in rear wheel? JD5065e, 2013

[Rmiked]

I took a picture of my very muddy rear wheel on my 2013 5065E. There is a pair of holes near each of the 4 inner disc to rim attachment points. One hole is square and one is round. Additionally, there is a pair of round holes (making 10 holes total) that forms a line that bisects the center of hub. I looked at some newer 5065E tractors and they appear to only have the pair of round holes (2 holes total vs 10). Looking at older tractors like mine (2012, 2013) the hole pattern is same as mine.

For some reason Deere changed this hole pattern in 2014 looks like.

Anyone have a clue as to what they are for? Is it an attachment point for assisting in lifting or mounting tire? And if it had a legitimate function, why was the hole pattern changed on later tractors?

Thanks

Wheel weights?

Could be? I always thought that with fluid in tires as routine option, and the relatively slow rpm of wheels, balancing is not something done on tractors. But I have no clue. Since the newer tractors (2014 to current) don’t have 8 of the 10 holes in my wheels, it’s even more curious.

Goggle "john deere wheel weights", look at the images. These are heavy weight ones, not to balance the tire.

The holes are for mounting the wheel weights.

You have the centers part number SU28371 for what should be the R1 / ag tires and corresponding rims.

Ditto what dodge man stated about holes are for attaching wheel weights

Man, do I feel stupid. “Dodge Man”, you are correct. My apologies. Since I have filled rear tires (and I’m kind of a tractor rookie) I was not thinking of wheel weights.

Now if I see wheels on newer models with only the one pair of holes (bisect the hub center) , is it because they didn’t get the Ag tires? I would hate to get some non-Ag tires and later want to switch to Ag tires, and not be able to put on wheel weights if desired. These wheel assemblies are expensive. Glad I have the option.

Tires, Ag vs Industrial R4 vs lawn, usually need different rims.. can get expensive.. and "wheel weights" can mean different things.. as you found out..

Don't be feeling stupid...

Hey, they say the only stupid questions are the unasked ones. After your post I had this image of wheel weights, like the ones used on cars, sticking out of those holes.
