pic: Spotted at IRI: New AM wheel (2)

[IndySam]

Whoooo, just got my wheels from AM!

Sometimes it's cool to live in Indiana.

One thing I like about these wheels is how clean they should be regarding chains. It appears that a 33-tooth #25 sprocket can be mounted flush against the wheel without chain interference (side to side against the tread as well as hitting the wheel around the sprocket), can anyone confirm?

I just got our wheels yesterday and they look great! We'll hafta wait and see how they hold up, but I'm not very worried about that. The wheels seem pretty robust. I really like that we aren't going to have to make up spacers to mount sprockets. I'll give some more information as soon as these end up on our bot.

Any update on these? How are they holding up? Does the tread stay on without rivets? Also will the 4" version come out before next season?

We just heard some preliminary results from the Mission Mayhem competition: the treads are staying on without rivets if the width of the tread is right at 1"

More data is needed to make a conclusive decision, though.

As for the 4" version of this wheel, we will not be making these until next summer.

Better call up Wayne Szalinski or invent a shrink ray yourself.

thats good to hear that the tread retention is working. Although it is a monstrous bummer that the 4" version won't be ready. That's the size that we would most likely be shooting for. I guess custom wheels it is.

The tread stayed on, but is there any way of testing whether it spun separately/slipped on the wheel itself under high loads?

Just curious.

Make a mark across the tread and wheel with a Sharpie? This is obviously not the most precise of methods as it will not be able to determine how much slipping occurs if it is greater than 360 degrees, but it would be a start at least.

EDIT: I just realized that this question may not be asking how to actually perform the test but rather if someone has or could perform the test. If it is the latter, ignore my comment.

Looks nice, I hope they will work just as well as the IFI high traction, which i really liked

This is the first feedback we have heard. Can you provide more details? (pictures, how it happened, etc.)

Terribly worded on my part....

What I meant is can someone who has these wheels perform such a test.

We will put these wheels to the test Saturday morning but having these wheels in my hand I can tell you there is no way the tread will spin on the wheel. The tread is gripped tightly on the sides.

If a failure is going to happen it will be the tread coming off not spinning.

We have one tread cut just a couple mm's short and my guess is that that wheel will more than likely fail. The others that have no gaps between the ends seam very secure.

We will see.

I hope they don't fail as well, but there could be a couple hundred pounds of force (depending on gearing, wheel diameter and tread CoF) trying to get them to slip.
