I have polyurethane tires installed on my Jet 14” bandsaw, and good suction on the under-table dust port. Nonetheless, when cutting woods like oak or cherry, much of the sawdust is carried on the blade and rains down on the table, and sawdust coats the tires where the blade contacts them. Despite having a brush on the lower wheel, the sawdust seen in the photo built up after ripping an 8-foot long one-inch thick cherry board. I have repeatedly needed to clean the tires with mineral spirits and a wooden scraper. What’s going on?

A guess - what with all the mineral spirits and scraping you have lots of static electricity attracting dust to a too-dry tire. Suggestion - a final cleaning followed by a thin, really skinny coating of wax.
Mind you, I could be way off but you've tried everything else.

If you want to fix this, you have to improve the dust collection.
Dust seems to laugh at the brush on the bottom wheel - If you think about it, this should not be surprising - dust falls down between the blade and bottom wheel and is very firmly pressed against the wheel by the blade. By the time it reaches the brush, it is firmly stuck.
Your best solution to this is to rig up dust collection before it reaches the wheel - possibly under the table (easy if you never tilt the table but harder otherwise)
Personally I find it makes no difference to the cut and stops accumulating after a while so I leave it alone.
I’ve never seen this problem on either of my bandsaws, one has no dust collection, the other I use inconsistently. Both have urethane tires.
My thinking is it’s the tires, not dust collection.
I would given it a try but I would think Boeshield, wax, etc you risk the blade slipping, but it can always be removed.
Is it actually impairing the performance of the saw?
No, but it hadn’t happened in the past. The sawdust falling on the table is a real inconvenience if I am doing a lot of sawing.
I get the same thing on my laguna band saw, maybe more so since I removed an angle plate from under the throat plate that directed debris to the dust port, I will put a new one tomorrow.
I have the same problem, I use a brass brush with light pressure and turn the wheels by hand with the saw unplugged.
My tools are stored right now but, I could sort of get to my 17" bandsaw. This machine has been used since 2007 with no special attention to the tires. Sorry about the pic quality I had to reach out with my phone and zoom since the saw is stored and walled in with other items. This is the upper wheel but, the lower looks similar. There is a bit of glazing on the lower wheel. I do have a brush.
You can see the line where the 1/2" blade has been run on it for the last several months before shutdown. There is dust and so forth present but, nothing really pressed into the wheel like you show. This makes me want to lean toward dust collection as the culprit.
I did do the DC modifications that are often discussed on the forums;
- Built a collection point directly under the table.
- Closed the factory collection point at the top of the lower cabinet.
- Sealed off the lower cabinet collection point.
Pictures of these things have been posted prior but, I could re-post if they will help.
