Default Cupped Tires?

Can someone tell me exactly how to tell if my tires are cupped. Heard the term several times, but was never really sure how to spot it. I have about 9100 miles on the original tires. Tread depth measures just about 3/32 and I've been getting a bit of a wobbly feeling lately. This just started. I was trying to make it to 10K on these tires.

Thanks

Look at the edges of the tire and you'll be able to see it. I'll try to find a picture of mine, it was pretty bad

cupped tires will howl or hum when turning.u can see it or feel it, the leading edge of the tread will be worn more than the trailing edge.

2/32 is usually considered the end of life for a motorcycle tire. Improper inflation can cause cupping, but in your case I'd say it's just part of normal wear resulting a tire that's reached the end of its useful life.

Look and feel. Run your hand along the tread area and if you feel anything other than a smooth surface, time for new shoes ��.

For what it's worth, I dug into it last year when I had noticed mine was cupped. Original tire with 16k on it. I found my tire gage was off by 2 psi, so it was running a little over inflated, which I think was the cause. I was still happy with 16k.

Cupped tires look like "hi-low" carpet. And believe me/us, you can see it and feel it.

Thanks! I just checked the tires and don't see any of those issues.

If you have a flat spot on the rear (tire no longer has an arc) it will wobble in turns as you transition off the edge onto the arc.

Stock HD worked OK until the cold wet weather arrived, they are a chunky tire and they just don't get heat into them.
I did a couple of posts about them on FB and got all the "learn to ride" comments.
I wanted to keep my EG all Harley but i am reserching alternatives.
