new tires scary at speed

[RichDesmond]

You guys do realize that road racers almost never balance a tire and it doesn't bother them aside from some vibration?...

Huh?? I roadraced for many years, all the trackside vendors balanced tires before handing the wheels back. Can't say that I ever saw an unbalanced tire go on a bike.

... Balance will not cause wobbles...

Agreed.

I'm just saying, it was "dead solid" before, new tires and not solid after, and the install was incomplete/incorrect, I would look at that first. That said, your suspension is probs shot too. And others here are def. better experts than me, particularly richdesmond.

I suggested balancing the tires just to be sure they are right to begin with (helps to eliminate vibrations and oscillations from the equation). It can also help the balancer operator to identity if there are any obvious irregularities in the tire/rim while its on the machine.

Now on cars Ive had on a couple of occasions had tires that "felt funny" or pulled to one side after I had them replaced. On one car I took it to a shop and they spent a bunch of time aligning the front end and checking worn parts and eventually diagnosed the problem by putting the tire on the rear of the car and the pulling went away. It was some type of "tread separation" issue that I couldn't see no matter how much inspecting I did. The Goodyear dealer didn't seem too surprised though and replaced it.
The other was actually just the opposite, it always pulled a little and I assumed it was just out of alignment, and when I replaced the front tires the pulling went away.

What I'm getting at is, I suppose one could get a "bad tire" that would have a problem that would be invisible to the eye and still cause some odd problems, and on a bike Im sure it would be more pronounced than on a car or truck.

Check and see the tire bead is set in proper. Mine wasn't one time when I had new tire installed, could feel a wobble right off the bat. Or you could have an out of round tire.
