New tire

[Guest]

My new back tire is not round and I know my rim is fine . I wrench everything else but I've always had my tires mounted and balanced. Is there an easy way to tell if the tire was poorly installed or is defective?

That sux ! Why do you think this ? Get the bike on the center stand, running in gear, wheel spinning. Can you get an eyeball on whats the matter / or a short video for the know-ologists..

It's off the bike right now. My friend caught it. We had it up on the center stand and I put the bike in gear and he saw the wobble when it started spinning. If you spin it by hand, it stops at the same "low" spot every time. The Yammie shop is going to take a look at it Monday for me (they're idiots at the Suzuki shop).

There are concentric circles around the bead, near the rim. Small fine lines, about 1mm apart. They should be parallel to the rim, with the same line showing all the way around. This is an indicator to ensure the bead has set evenly all the way around the tire. It is easy to get the rim only part way seated, or seated unevenly.
You tire could also be damaged, like a kink in the steel cable inside the bead, or some form of delamination starting up. Having a second shop look at it is a good idea.

I have seen a few tires with "concentric circles", but most of them that I have seen only have one.
Regardless, the principle is the same: it should remain a constant distance from the rim all the way around.

The correct pronounciation of this would be "know all of this".

Sounds like the tire isn't seated properly.

Thanks. I'll look for the circles. It'll suck if I have to buy another tire. This one is barely used.

You want to take a jaunt down in the rain? We also have a partially disassembled 1100 tranny that needs fixing .

Just went out and looked. Sure enough, the concentric circle is not equidistant from the rim all the way around. When I take it to Yammie, I'll have them look and see if they concur.

Maybe it just needs to be reseated. It happens sometimes, not enough lube or whatever. A competent shop would have seen it and fixed it before they gave it back to you.

The local Suzuki shop were the incompetent louts. The Yammie shop did my front tire and that has been perfect.

There ya go.

I would expect that all they will need to do is let the air out, break the bead loose, spray a bit of lube on the bead and inflate the tire. It should not be a big deal.
