Is there any significant size difference between your new wheel, and the AKA evo wheel?

I'd like to continue using my JC tires on the AKA rims until yours are released, if that's possible.

Also, is it needed to trim the insert as well? (CC)

Just trimmed the bead off of an old tire, and man you have to be careful, cut a bit too deep some places.

Did I do it wrong, or is the mounting area, or "new bead" really small?

I was talking to mark pavidis of AKA when they came to FL, and the reason AKA's new evo rims are not roar legal is because the glue bead is slightly to wide. So that would be the reason why the JC wheels new bead you made seem "small".

I have not seen the new JC wheels in person yet, I was practicing with JR Mitch yesterday at NRH, but I was not scoping his equipment out to see if he was testing them, or not.

Hi - A couple questions:

1. I noticed sometimes people sand the center section of the tire almost removing the center lugs. In what condition would you do this?

2. Is it ok to run CC in rear and stock 3/4 rear foams in front or should I go CC all around?

Thanks JC!

1. I do not know this answer, as I have never seen this done.

2. I only run 3/4 rear foams in the front of my buggies, as I do not like CC on a rm car. I also run CC rear foams, and personally like this combination.

Hmm...I thought that the AKA wheel wasn't legal because they made the bead dia larger than the current standard wheel. Where are details on the new JC wheel?

Larger/wider, if you look at the bead it is not flat horizontally instead of vertically. Thats what I meant by wider.

Um...what?

When I think wider I go to wheel width inside to outside. Larger dia is the wheel or bead dia.

I'd do WAY better if there were some cross sectional images to look at.

Edit: Ok so my understanding of what AKA did is correct (just watched a video with Mark P). They brought the wheel main OD (not including center ribs) up to the OD of the outside ribs on a standard wheel. Mark talks about it making for a lighter wheel/tire/insert combo (IMO would be great for stock racing) and the ease of gluing. Bringing this home for the JConcepts thread is this was JCon has done as well or did they go a different route? I'd love to hear that they did the same thing as that would help pave the way for ROAR approval IMO.

I hacked up an old tire just to see how it'd mount up to the EVO wheel, and I have some doubts.

The red part is the new "bead", and it only measures 2.33mm +-, I don't think that's going to hold up to mod motors very well IMO.

The bead on the AKA Evo rim measures 4.70mm +-. Huge difference.

I think I'll wait until dedicated tires come out, don't want to mount up some nice tires only to have them ruined.

Hopefully they'll be out sooner rather than later, but till then I'll stick with the U shaped bead.

back the chuckwagon up. 2.33mm is plenty. Kinwald glued tires together only using the thickness of the base of the tire(ie not including tread lugs). You drive on these now called BK Bars, Barcodes, etc. CA is some powerful stuff.

We decided to keep our new Bullet wheel the same size as the evo wheel; which is 60mm or 2.4" O.D. This will more than likely become the new industry standard even though it's still illegal for ROAR/IFMAR events.

Check out this vid from the Cactus where Jason explains the new wheel starting around the 2:30 mark

+ YouTube Video
ERROR: If you can see this, then YouTube is down or you don't have Flash installed.


Give me some time and I will try to explain things a little better.

Generally this would be used in a higher bite situation and the outside patterns would be left to keep the edges from grabbing real hard. I think the bro codes resemble this a bit. Many indoor places do this where the track changes between treaded and slicks.

Hope this helps.

What is the red compound for 2wd buggy front dirtweb? Is this a clay tire or for outdoors?

Red is designed for blue groove/hot weather conditions and falls between Blue and Orange. No relationship to Gold/Clay compound.
