Default 2017 WRX Limited - clunk from Base wheels

My car is a 2017 WRX Limited. The original wheels (Premium / Limited) have summer tires (first pic), have no issues, as expected.
For winter tires I have a set of 2015+ Base wheels (second pic).

When I mount the Base wheels there is a considerable clunk, from at least both front but it seems all four, when I hit bumps / potholes on the road.

I use the original lug nuts on both wheel sets, torqued to 85 foot pounds.

The only things I can think of are the original lug nuts are not compatible with the Base wheels or the rotors are different in some way, between Base and Limited.
Both of these theories seem unlikely.

Help me out knowledge base.


Thanks to Joe Spitz, for the pics!

So, 57 of y'all read this and no called me or insinuated that I'm an idiot.
I'll assume this is a stumper.

I do the same thing but no clunk. Same lug nuts for both sets. Just mounted the 17 base wheels 2 days ago for the 2nd winter with them. 33 psi front/32 psi rear. Quiet.

Thanks, JR!
Now I'm really stumped.
I rotate them front to rear, when installed each fall, from the previous winter's positions. If it were one whopped wheel, I'd think at least the sound would change. It seems like it's all of them, at least the fronts.
I'll pay closer attention, when I put them on soon.
I was hoping to have some theories before install. I guess I'll look at them really hard, when I take them out of their sleeping bags.

Measure the depth of the threads with the base rim on. measure the depth on the oem lugnut.

Both the Base and Limited wheels left the same amount of thread exposed for the lig nut and the lug nut had enough depth to accept that amount of thread.
That was a great idea!

I'm really stumped at this point.
I'll have to really pay attention to which wheels do the clunking.

I'll have to really pay attention to which wheels do the clunking.

are you sure it is a wheel related noise and not a suspension related one?

ball joints?
tie rod ends?
top hats?
lower strut mounting bolts?

can you repeat the noise over the same bump at the same speed consistently? different speeds?, slower?, faster?

are there any items in the car, back seat or trunk, that could be causing the noise?

is something loose under the hood?

have you had the 17s checked for trueness or out of round?

Have you tried mounting the tires on a different wheel?

Do you thing the noise(s) could be temperature related?

It only occurres with the base wheels /winter tires.
I do not believe it to be suspension related.

I have not had the 17s checked for trueness or out of round.

I have not tried mounting the tires on a different wheel.

Thanks for your ideas!
I will keep them in mind

Is there TPMS hardware rattling around in the wheels, maybe?

Does that happen?
Do TPMS sensors get loose?
It only happens on sharp bumps, potholes.

It can. Sometimes hitting a pothole can break the attachment to the sensor, leaving the sensor to rattle around inside the tire.
