Hey all, I got my rear tire changed on Thursday, and since then when I hit 65 to 70, I got really wobbly. In my mind, it's something to do with the rear wheel since that's the only thing that changed since then. I didn't do the change. Is there anything I can do or check beforemail talking with the shop about it? Thanks for yalls time

 

Use a floor jack to lift the rear off the ground. Start it and run it through the gears and check for an out of round or out of balance tire.

 

Also make sure your belt is the appropriate tightness, and that both ends of the axle center are equal distance from the 'check holes' ( small hole, about 1/16 diameter about 3" towards the front, in the swingarm)... and that your axle nut is snug.

 

You're right that it's almost definitely your rear tire since that was recently replaced but it wouldn't hurt to check the front tire, visually. If the front is worn on the sides (into a V shape instead of rounded like a U) that will cause a wobble.

 

Yup. Make sure your rear wheel is aligned correctly.

 

Check tire pressure. Cured my buddies.

 

If the new rear tire was not balanced it would wobble.
Some don't worry about balancing the rear tire,

 

This is the first thing I would check too, but check both.

 

Ditto on checking the tire pressure,
Could be balanced incorrectly or the weight came off.
Also could be the front motor mount, possibly didn't notice before because it was a gradual but after the tire you were more aware of things, "looking for issues."

 

I had the exact same issue, and I chased every possibility posted here. Tire was balanced, alignment was spot on, motor mounts fine, spokes, etc., everything checked out. I ended up replacing the tire and the wobble is gone. Good luck!
