Did you try cleaning the tires, scraping them with a blunt chisel gently and carefully?
Look up Bill Carter blunt chisel technique.
Make sure your belt is not knackered, you can buy belts cheaply in lawnmower places and such for a fraction of a tool brand one, bring the belt with you.
If they're cleaned allready, I would guess they need dressing.
Do not try this untill you have ruled the underneath guidelines first.
Here is what I've had to do a few times, not got my machine quite right yet as the lower tire had a huge lump taken out from it, which I tried to smooth off by crowning, which wasn't a good idea.
I had nothing to lose though ( I thought), and your machine sounds like it works somewhat....
Thats probably the difference!
I took it back to flatish but its still not right...
If I had filled the missing lump, and dressed it flat it would have been sorted.
I ended up buying a new tire but yet to fit it.
You can get good results doing this method, but know first what profile the tires are meant to have.
From this
To this, still not there yet but you get the point, my tires are flat.
Doing this method made my saw a lot better, as the blade was all over the place before.
A few things I will mention first though
Presuming you've tried all other adjustments, as this ones a permanent one.
I would not do this if I hadn't done an awful amount of adjustments, but the twisting comment made me write this post.
Presuming, you've watched all the videos first, and tried differing methods like the Snodgrass one aswell as the coplanar way of going about things, and tried the same adjustments with both settings.
You've looked at the Rikon bandsaw adjustment PDF for the counter procedures of various problems etc and tried them aswell.
If you have tried all else then the way I go about it is as follows, not advising you to do so though!
Attempt this at your own peril
First thing is cut a sheet of plywood to cover the base of your machine...
Yes, you will drop something and chip a huge lump of paint off the machine base.
Get a square block of hardwood and lap the side of a plane iron to make a tough scraper.
You need to be very careful about inserting the scraper into the rubber, as you will cause a split on your tire if you do this wrong!
The scraper needs to be facing away like a scraper plane angle
The f-clamp is just right tightwise and I can twist the block with the clamped plane iron...
Too much and you will damage the tire with a split.
You might need to block up around the back of the machine to get the large f-clamp to fit, and play around with the angle of timber facing into the saw cabinet, before clamping up the blade onto the block.
Then get blisters on your fingers spinning the wheel for ages.
Did I mention cut a sheet of ply for the base because you will chip it, first thing you should do
before anything else tire dressing wise, because all that awkwardness will make you forget about the paint job.
Tired now, so I may not be making sense
Do all else first before going at tires.
Take a picture of the jacking bolts before going at them also, as you may want to know
exactly where they were originally.
I may be forgetting something regarding tire dressing , so don't rush out and try that.
As simple as a bandsaw is, they can be very troublesome.
