I don't think those honey-comb looking tires will help gas mileage, and they'd clog during mudding. What a mess that would be to clean dried mud from honey-comb holes.

No offense intended, but what do airless honey-comb tires have to do with a gas mileage thread? Seems off topic to me.

I'm more interested in reading about you heating gasoline to (hopefully) make combustion more efficient.

Old people in old large Cadillacs scare me in my relativley puny little Jeep. I could have nightmares about this.

Those are just pictures of a prototype tire that's been floating around the Internet for a few years. I would speculate its a cut away tire to show how the honey comb design works, the production tire if there is one would have a full carcass.

I just ordered a Dynomax cat back system for $150 from Quadratec. Free shipping of course.

I want a new down-pipe without the stock dent.

Can I get a generic down-pipe from any local muffler shop, or do I need to order a name brand down-pipe from online?

Possibly a stupid question, but I'm a newbie at this topic.

OK, but how does it relate to gas mileage topic?

Well it could eliminate improper tire pressure mileage issues.
Seems like it could also eliminate the ability to adjust inflation pressure to match varying load needs.

Get one made. That's probably the best option for you with the set-up you are running.

These are a little beyond prototype. They are in production now for equipment. We have several sets on site. The guy I talked to had an *** of pictures and had laid hands on the automotive versions. He too built Jeeps in his spare time and told me how they would affect us. I'm still trying to get wrapped around them. He's telling me that they will improve road and MPG performance without sacrificing too much performance offroad. The rubber tread is effectively harder and deforms less when traveling. The "spokes" of the wheel deflect when offroad. I'll see him again in the next week or so and I'll try to get his videos. I've seen the generic stuff out there, but when a guy shows me a video that he is in....I tend to lend some credibility to his story. Considering his company is selling the equipment versions now, he might know something.

Honeycomb tires are not anything new...
What happens when snow, mud, rocks..... Gets trapped in them.
It really does sound great, but I don't see them taking off anytime soon.

From what I've read online about these honeycomb tires is they are extremely difficult to balance, therefore no street tires. Also, if they do become available to the public, then there will be a "skin" on the outside to keep snow, rocks, mud, and whatever else out.

OK. I'll get a new down pipe made.

Is the stock headers/manifold good enough performing to keep using, or replace?

Hmm. OK.

But... Harder rubber has traction problems in a Northern (colder) climate, especially when cold and wet.

Harder rubber on any type tire increases gas mileage at the expense of wet traction and especially Winter traction.

Harder rubber has less rolling resistance than softer rubber, but harder rubber also has less traction on wet surfaces, cold surfaces, and especially cold wet surfaces.

Hard rubber is incredibly slick on wet snow or wet ice (near 32F). Like so slick it can't even be adequately described in words. I experienced it in the past when I had hard rubber treads on a Wrangler and another vehicle.

For example, traditional highway touring tires have harder rubber than all season or all terrain tires. Some commercial traction tires have really hard rubber too.

===

The only exception to that rule (TIKO) is tires with silica in the tread. The rolling resistance is LESS and traction is MORE. Thus achieving what was previously impossible. You have cake and eat it too. At least that's Cooper's description of the benefits of silica in the Cooper AT3, and so far I believe based on wet pavement. Next Winter will be an interesting test of the tires and Cooper's claims.

If Cooper's claims are true (and I tend to believe they are likely true), then I would assume that silica would have similar benefits in other brands of tires. However, as you asked, how much silica is in a given tire, and how much is best? Good questions. I don't know.

===

Wouldn't honey comb tires be expensive? You'd be replacing the tire and wheel every time.

I did not read every post so im not sure if this has been mentioned.. Indexing your spark plugs.... cheap and worth a try.
I like this thread im going back to read more of it now.
Keep trying..

Indexing spark plugs has not been mentioned before, AFAIK.

Please explain.
