Front wheel wobble at low speed

Since I replaced my front wheel several months ago (Pirelli), I have noticed it difficult to keep straight at slow speed. This is not the normal difficult due to balance at slow speed and there are no problems at higher speeds. I thought at one point it may be road groves or the surface, but ruled that out. Could my front wheel simply need the balance checked or could it be a problem with the tire itself? Actual tread? Any other ideas?
I've been riding about 14 years and this is a first.

Thanks

Take a look at the tire, typically there is a yellow dot on the sidewall, meaning this is the "Light" spot on the tire and this should be closest to the valvestem. If there is no yellow dot, it means the spinout was zero balance. Next check your air pressure and be sure its within the specs mention on a lable somewhere on your frame or owners manual. Next thing f you strike out on the last 2, check your suspension settings and be sure your not running too soft. I doubt you made any changes from your last tire, but check anyway.
If all three do not cure the problem or no problems found, I would lean towards a rebalancing.
Hope this helps.

If you can, suspend the front wheel off the ground, give it a spin, and see if the rim itself is either bent or out-of-true.

If it seems out of true, how would I adjust that? Also, should all the spokes sound the same as I turn the wheel and let something hit them? What if I checked the torque of each spoke, would that help?

Also check that the tire bead to rim alignment is even on both sides all the way around.

I wouldent go as far as setting torques for each one but if you
can roughly get them all to sound the same as the majority,
think of a tuning a guitar more you tighten the higher pitched it will get.

is there any side to side play in the wheel if you waggle it while it's
suspended?

No sideplay in the wheel, in fact nothing feels loose.

is this new front tire different in profile than the old tire was?

being rounder or squarer could be what your feeling.

This is the same brand/model tire as my previous one.

There are a few articles on truing spoked motorcycle wheels...I think this one does a fine job of explaining the basics. About the bottom 3rd of the article.

Good luck
Sean
