   Check the obvious first. Is one of the wheels mounted improperly, etc?

   Assuming all that's good, do the new tires make the wheels eccentric (larger diameter in some parts than others)? If so, you may be able to turn them down a bit using one of various metods.

   Hi Pete,

   I only took off the upper wheel which i've done before. It went back on fine. How would I check for eccentricity? I'm assuming that just measuring across the wheel at different places wouldn't tell me much. Any suggestions?

   Thanks!

   Put something so it just ticks the wheel at the highest point, then measure the farthest the wheel gets away from that point.  Also, spin the wheel by hand and see if there's a visible wobble or change in behavior.

   Thanks Pete. I'll give that a try. Before that, I'll try running the screwdriver around again and see if that doesn't even out the stretch some more as suggested by *desertmaster*. I'm not out any $$ on this, so may go to some aftermarket tires if I don't get this squared away.

   Thanks for all the input.

   One of the new tires was definitely out-of-line in that it was wider by 1/16" and didn't really fit the groove between the edges of the rim. This caused an apparent bunching/high spot.  Only one of the older tires was grooved, so I re-mounted the better one of the old tires on the bottom wheel and have a new one the upper wheel. When I fire this puppy up, I'll let you know the outcome.

   I'll be back to ya in a bit.

   Thanks.

   Roy,

       You might try this, if you didn't already:    insert a round shank screwdriver between the rim and the tire and run it around the rim a couple of times. Sometimes the rubber can kind of bunch up in one place.

   All this hoopla about changing bandsaw tires is just that in many cases.  I have used bandsaws on a daily basis for 50 years and have only had to replace one set.  This was on a Delta 14".  In this case, the tire stretched and caused the saw to vibrate. Tires should not be excessively worn, torn or cracked or loose enough to slip or get out of balance.  Keep them clean.  If you observe excessive wear, then something is causing this and you should locate the cause and fix it.  Tires should last many years if a saw is used as it was intended.  If your saw is not running smoothly, it probably is something besides your tires.

   Good point. I thought all other parts were running as best as I could make them. I'm in no hurry, so I can fiddle some more. Just looking to get the best I can.

   Thanks for all the input.

   Wdrite had better luck than I had. The rubber tire on my 12" Jet drive wheel went limp in about four years. Rubber parts do have a limited shelf life. Climate even has an effect on length of life for rubber parts. They tell me that ozone plays a part. Replacing the tire made it work as new. My Delta 14" has what looks like polyurethane tires with little or no crown. It seems to work better, too.Cadiddlehopper

   Yes, I've seen ozone destroy rubber fairly rapidly (like the gasket around my car windshield when I lived in So. Calif.).

   My problem in this instance seems to be that the replacement tires were dimensionally worse than the factory tires already on. Put the factory tires back on and will seek other replacement(s).

   Thanks again for the feedback and input; it has really helped this bandsaw newbie

   If the factory tires work I wouldn't bother.Pete

   I'm back to the status quo and happier for it. Not tire related, but I swapped the factory tensioning device for the Quick-Crank. Now I'm psyched and have the whole weekend to saw out some freebie walnut!

   Thanks, Pete.
