The Delta wheels have a crown built into the rim, so you should be good to go after gluing them down. However, crowning them after installation is still a good idea IMO, as it will diminish any run-out that may have been present allowing the blade to run smoother.

How does one “crown” them after installation?

LOL – there are probably as many ways as there are bandsaws :)

This Vintage Machinery Wiki article should get you started though: Tire Crowning

I’ve only changed a bandsaw tire once. It’s a grizzly 17” saw. I did not crown the tire. It seems like a lot of bother – especially since the wheel is crowned. I think that should be enough to cause the blade to self-center.

Also, my tires were not glued.

The new one, installed in the winter, however, was a very tight fit. I soaked it in a pan of hot water, to warm and soften it a bit, then quickly dried it (with a cloth followed by a blow dryer), then stretched it on using two round-shafted screwdrivers (only the round shafts pulled the tire). I only replaced it because the original tire on the upper wheel had become loose. The lower wheel still has the original tire. I didn’t see any point in replacing it, even though I bought a pair of tires.

The Delta 14” cast saws and the clones along with a lot of Asian saws have crowned wheels so it is not necessary but most old iron REQUIRES you to crown the tires. The same thing with gluing, most Asian saws tires do not require gluing but you usually can’t get away with not gluing tires that should be glued.

You are beginning to find urethane tires made for older saws that include the crown in the mold an example are the tires for the older Delta 20” saws with the T shaped tire.

My new tires were urethane as well. A very pretty orange.
I just heated them up in a pan of water on the stove (per instructions) and stretched them on. No adhesive.
The wheel has the crown not the tire. I let it cool and set overnight and off I went. It’s been almost a year without issue.
