   I wonder if it could be strain on the bearings that isn't there without the blade. Try running it with light tension and gradually tighten it, see where it starts.

   Turning the wheels , bottom with the motor or by hand and top by hand , I doubt visually that you could tell if one or the other has a slight wobble. Have you tried another blade? Small things can translate to a big wobble, for example, a little tweak in the blade or a bad weld. A dial indicator would give you a more accurate idea if one of your wheels is the problem. If a wheel is off kilter that could be a bearing problem or a bent axel or simply something loose and needs tightened down. Try cleaning your tires, a bit of gunk stuck on there could cause the problem. Back your guides off so they cant touch the blade as it turns and eliminate that as a possible problem. But tires do wear out eventually.

   decreasing the tension did seem to help. Different blades all act the same. I will buy new tires. Anyone have experience with the $15-$25 tires in comparison with the $50-$60 ones? Those seem to be the two price range choices.

   If new tires don't do the trick, your upper and lower wheels may be out of alignment. I've only experience fixing that on a Rikon 14" and I imagine it's different on every saw. But basically, you need to get the two wheels coplanar. The bottom wheels usually has a bearing that has four screws at right angles to each other. Loosening the bottom and tightening the top (or vice versa) will change the tilt of the wheel front to back and the two side bolts left to right. I had to make a gauge out of a long thin piece of wood with two blocks attached at each end to I could contact both wheels and see how if they were vertically aligned. I bring this up as a last resort -- it's a bit of a rabbit hole, but in my case, actually fixed the problem I had chased for quite a while. So try the tires, a different blade and play with the tension. And if your saw still feels like a jet engine at take off, then you may need to go this route.

   What kind of saw is it, and how old?

   Clean the tires, clean everything, and put on a brand new good quality blade. Eliminate the simple first.
