A Sawsall does NOT work.

A Dremel Works but it goes there a LOT of disks.

A Hacksaw won't work either.

You cut the bead (thick wire bundle) with a bolt cutter and then the rest of the tire can be cut easily with most any power tool with a hardened blade for cutting metal. You can use a circular saw, a jig saw, a sawzall. The slower the blade moves, the less smoke / burning the rubber occurs

A dremel is definitely not the answer. 4.5" Angle grinder with a 1mm or 2mm thick metal cutting disc. Any 'el cheapo' angle grinder will do, I personally use Smith & Arrow brand cutting discs and find them very good but any decent brand will do. Cutting through the layer of wires in the bead generates a lot of heat so you will get a lot of rubber smoke.

Absolutely! A water cooled Carborundum saw blade. We have cut automotive spark plugs *lengthwise using a Carborundum Blade with a Pistorius Saw Frame spinning the Carborundum Blades.

HI, if a saw's all does not cut it then its operator error.. with the right blade a saw's all well cut all most anything

I have been around when tires are grooved and they used a hot iron. Are you trying to cut a tire into pieces? A tire is extremely difficult to cut because they have a band of steel in them.

Sears tire cutter

An ice pick or a knife would certainly do the trick.

Angle cutter if you want to quarter them - goes through the bead like butter.
