Yokohama Tire Technology Cuts Petroleum Use in Tire by 80%
www.greencarcongress.com ^ | 13 Feb 2007 | Staff

Posted on 02/15/2007 10:40:16 AM PST by Red Badger

Yokohama Rubber Co., Ltd. (YRC)—the seventh-largest tire manufacturer in the world—has developed a process that combines citrus oil with natural rubber to form a new compound it calls Super Nanopower Rubber (SNR). The major component of citrus oil is d-limonene.

The process reduces the use of petroleum products in tires by 80% and is part of YRC’s global EcoMotion environmental program. The first SNR product is the Decibel Super E-Spec, an all-new consumer passenger tire.

The fuel-saving E-Spec tire features an air permeation suppression film, a polymer lining designed to reduce air leakage from the tire, therby helping to maintain appropriate inflation levels.

Underinflated tires consume more power, thus using more fuel. The E-Spec is also a lot lighter and conserves gasoline by reducing rolling resistance by 18 percent. Low rolling resistance tires improve fuel efficiency by minimizing the energy wasted (as heat) as the tire rolls down the road. —Jim MacMaster, executive vice president, Business Division, of Yokohama Tire Corporation

The E-Spec tire featuring the SNR compound will be available in Japan later in the year, but no date has been determined for release in the US market.

Good article! I've heard more about underinflated tires lately, yet I've not checked mine. Shame on me.

I am involved in the rubber industry, reducing the amount of petroleum in rubber has seen an industry push for several years now.

Molding the stuff is another story though, most of the stuff I have seen tears way too easily when hot, de-molding it can be a real problem, I wonder how they overcame that, will have to check that out.

Yes, a very interesting concept but I haven't heard anything about it for a while. I build rubber molds, but tire molds are a science all their own. It's a very specific niche that has so may trade secrets its darn near impossible to attempt to build one without hiring (stealing) a team to do it from someone else.

Just a couple thoughts:

1) Does "reduced rolling resistance" equate to lowered braking ability?
2) Citrus Oil? Is my morning OJ now gonna cost more so someone feels better about the fact they aren't using as much petroleum in their tires?

I don't know about that application, but Yokohama was the tire to have for autocross in the 90s. Lotus also contracted specialized tires from Yokohama for its racing-oriented cars, like the Exige and 340R.

So, we are going to go from needs of less petroleum, back to the needs for more real rubber....

Didn't we invent artificial rubber strictly to get away from the strategic need for it?

Can replace oil in a tire tommorrow with real rubber, hell, that's what all tires were made from prior to WWII if memory serves.

Not discounting the technology, just more curious about it than this little excerpt portrays.

If all they are doing is moving from the artificial rubber from petroleum based products, back to natural rubber as primary ingredient, really haven't accomplished much of anything....

We have been tweeking rubber compounds for a hundred years, I would be very leery trusting my family to something until it has been on the road for quite a few years. Hundreds of millions of dollars have been spent engineering rubber compounds that you can guarantee will not fail under certain conditions, I just wonder if all those conditions have been tested with this compound yet.

Not necessarily. A cylindrical or spherical body rolling on a surface is slightly flattened at the contact points, because of the load carried by the rolling body. This flattening is not fixed at one point with respect to the rolling body, but moves in a direction opposite to the direction of spin of the body. This frequent distortion, which causes internal friction within the material of the body, is the reason for the resistance.


Now a body without rolling resistance would ideally be perfectly round in its cross section, when rolling, or would have zero internal friction within the material of the body, as it deforms. So if the case is the former, then yes, there will be less area of contact with the surface, possibly increasing the rolling body's tendency to skid. In the latter case, this is not neccessarily so.

I was watching wheels TV on spike a few months back where they test rode some.

I guess the biggest problem currently is they are very very very noisy.

Add rocks and mud to the equation, as you pointed out, I'd say they still have some work to do.

But I must say, I thought they were pretty cool looking especially when the car was in motion, it looked like it was floating.

This is something extracted from citrus fruit. Lock in your citrus futures now.

Right now its used primarily in cleaners and health food products. (Weight loss! Works on cars and people!)

Doesn't that mostly come from the peel though? I thought it was the waste that they used to get orange oil from, not the fruit.

They do extract it from the peel which is the byproduct of citrus juicing operations. I'm not an industry expert but I would expect that D-limonene would probably not replace a lot of petroleum or latex based tires. Sounds like a boutique product.

If it did become widely used I expect it would have the upside of a much nicer smell when the mobs start to burn tires on the barricades...

Would it impair a tire's ability to stop a moving vehicle if a tire were able to remain "perfectly round"?

I've heard more about underinflated tires lately,

Yes, you should check and adjust your tire pressure often. Check tire pressure first thing in the morning when the tires are cold; preferably before driven more than three miles. Adjust the pressure to the car manufacturers recommendations. However, it is more important that the both front tires are the same pressure and that both rear tires are the same pressure than they be the correct pressures.

Some tire sellers are using nitrogen instead of air to inflate tires, which decreases the rate of loss in air pressure. You can later mix air to the nitrogen.

I am not an expert here, but my guess would be that the tyres may be stopped by the brakes, but the reduced region of "flatness" at the surface of the road would imply less contact area of the tyre with the road, thereby leading to higher contact pressure there. This pressure could possibly exceed the pressure needed for catastrophic wearing of the tyre, which then might lead to the pulverised tyre material that forms between the stopped tyre and the road surface acting like tiny ball-bearings, leading to the vehicle to begin skidding.

I am involved in the rubber industry, reducing the amount of petroleum in rubber has seen an industry push for several years now.

My Dad has been either the buyer or the receiving clerk at a Goodyear plant for the last 30 years or so. He tells me that a typical tire is 65-70% petroleum products. I know he was working 14-hour days every day for weeks after Katrina, between the petroleum plants going down, and various other suppliers out of business. If we ever have a serious petroleum shortage, the price of tires will skyrocket.

Hopefully these new tires will actually amount to something and be useful. Too many times you read blurbs like this and nothing ever comes of the technology.
