Great job on diy bearing swap. I have to do that same one on wife's car soon. I re-engineered my bearing press to use 1" bolt up from 3/4 after I stripped three sets of 3/4 " bolt swapping the front right bearing on mine and wife's E53.

The 3/4" bolt is good for about 23,000# force the 1" is designed for 62,000#.

The math worked out to about 25,000# to install and 35,000 to remove the front bearing. Brutal, and destroyed the bolt and nut that came with the kit and the stronger replacement bolt as well.

The rear doesn't seem nearly as big and explains why you likely didn't have a problem just be aware if your kit like mine has 3/4" bolt it will likely not have the power to remove and replace the front bearing.

Very astute to realize good thing and the new noises. It's very bad when some constant noise masks the other telltale sounds of slow destruction.

The one negative of my new positively bad ass tires is that from 15mph down to about 5 they make a 500Hz down to about 100Hz hum that will mask some telltale sounds like scraping brake pad etc. it sounds very much like a worn gear in a transmission but it's subtle and only noticeable on deceleration so hopefully if I ever to get a new wearing part sound that will show itself on acceleration also.

The fact I can accelerate and brake with half the rate of dry pavement on slush makes up for it however. (I was able to achieve nearly 0.5g braking on wet slush)

I'm trying to figure out if I can use my bearing press to replace my rear bushings which are shot. They have a specific tool to do that swap but only that job. I'm not sure if the cups are big enough but I digress.

Awesome on the diy bearing swap sharing your post will definitely encourage others to do the same. Also *others*: this swap can be done without special tools, you can hack together a bearing press with some pipe flanges and large sections of galvanized pipe. For $20 or so vs $100 kit designed to do the job.
