Front end front to back movement

[79XS11F]

Well, tonight I decided to remove the front wheel and take it to the shop tomorrow, to have it balanced. I looked and there is no weight. I may have thrown it in my travels last season.

2 things I noticed...

1... the wheel spins extremely free when calipers are removed... I may not have installed these components correctly when I had the tires changed last year. Need to follow proper procedure along with new pads.

2... With calipers off and wheel spinning free, I held my finger perpendicular to the fender leading edge lip and observed what I believe to be the root of my problem. With tire spinning and finger almost touching the tire, I see a gap, flat spot, smaller gap, no gap, small gap, large gap, flat spot... repeat. Almost like a slight "bubbling effect".

MY TIRE IS OUT OF ROUND!!!

Would taking it to the shop and having it balanced eliminate or reduce my problem??

Are tires typically not perfectly round??

Or do I have a bad tire and need to shell out big bucks for a new set of shoes?

I also see slight cupping starting. Could the cupping be a result of an out of balance tire?

I also had a similar issue the first year I put my bike on the road with new tires. Because the tires were new I didn't even think to check them. after a week of trying to find my wobble I decided to stand up on th pegs and look over the front fender to see just what was going on. I did this at low speed and to my surprise I noticed the tread pattern on the tire moving back and forth at the center of the fender. Turned out the tire was defective.
