ALUMINUM EXPLAINED: PRODUCTION METHODS WILL NOT AFFECT STIFFNESS
How can we increase the stiffness of wheels? As long as wheels are made of aluminum alloy, using a different production method does not affect the stiffness of the wheel. That’s because all aluminum alloys used for forging and casting create same material property with identical stiffness.

You may think forging process creates stronger materials. However, when forged and cast aluminum alloys are measured by the Young’s modulus, it shows almost no difference between two methods. Forged and casted aluminum alloys are nearly identical in specific gravity as well. Therefore, if you make an exact same shape of wheels using forging and casting method, the weight of those wheels should be the same. What is the advantage of the forging process, then? It is an ability to produce higher material strength.

Generally speaking, compared with casting, forged material is superior in yield strength and tensile strength. However, no matter how great the material strength, it cannot justify an extreme reduction in weight.

Even with adequate material strength, if wheels lack stiffness, they cannot perform properly even with high-performance tires.

Durville Die Casting & MAT Process
Enkei has adopted two technologies – the Durville die casting and MAT process that ensure cast aluminum wheels have strength comparable to forged ones. In the Durville process, molten aluminum alloy is poured into the mold from its inner rim side, with the disc side facing downward. The alloy is rapidly quenched and solidifies, starting at the disc side, creating a finer metallic structure, significantly enhancing tensile strength, yield strength and elongation.

In the MAT process, the wheel rim placed on a mandrel is spun and rolled. This spinning process creates “metal flow” in the metal structure of the aluminum alloy, which is similar to the metal property seen in the forging process.

This hybrid process of casting and forging gives wheel high material strength while keep manufacturing cost more affordable than forged wheels. Additionally, it gives greater freedom of design on the wheel face.

Design Capability behind the best wheels

How does Enkei ensure its wheels have high stiffness? The answer is Enkei’s “Design Capability”.

To maintain high stiffness under great force, the wheel’s cross sectional area in the direction against the force applied needs to be enlarged. Unfortunately, the larger this area is, the heavier the wheel will get. However, if the layout, cross sectional shape of the spokes and the rim profile are designed properly, the wheel can maintain high stiffness without
adding weight.

The layout is made possible by Enkei’s vast accumulation of wheel design data and the computer aided engineering 3D simulation. In addition, Enkei strives for the largest possible weight reduction by identifying the wheel portions where stress concentration is least likely to occur and shaving down areas that do not affect stiffness.

Enkei’s processing techniques ensure the “strength” of its wheels, and its excellent design capability ensures “stiffness” and “lightness.” Enkei’s design capability is the most-treasured asset and essential for developing the highest performance wheels.

Best I've Tried
Color: Blue Shark, Size: Medium
With my pitty pup, there's no such thing as an indestructible toy, but this has been the most impressive so far. It's lasted days vs the typical minutes his new toys survive. It has a squeaker, but no fluff, and this has been great. He's been trying to get at if for a long time with no success! He has tore thru the rubber portion, but there's still plenty of play left in this toy. The 3 different textures keep him interested vs the hard material toys he rejects or chews on them too long and I worry about tooth wear. Definitely buying more.

Great product! Durable, chewable, awesomeness!
Color: Grilled color, Color: Grilled color
Very well made and durable. My dog hasn't left them alone since i opened them. Hes been at it for about 45 minutes straight now! Lol. He's an avid chewer. He will chew thru and fabric or cloth toys in less then a day. But these are what he really likes because they take time to chew apart. The shapes, are great, because one he props up with his paws and chews and it seems like it's easy to grip for him. Thru are hard so if you have hard floors it can get a bit noisy when he drops them. Over all this is a great product. Safe, chewable, long lasting, fun shape looks real to him (i think lol), Me and my dog Lucky are both happy with his new toys!

Recommend for very heavy chewers
Color: Grilled color
My aggressive chewers love these! It’s been a few weeks and still in one piece and man they chew them for hours on end.

Amazingly great product!
Color: Grilled color
I’m not just saying this, ok, this is not hyperbole: this is THE best nylon bone for chewing that I have ever purchased. And you get TWO of them for relatively less expensive than most chew toys give you one! I have 2 golden retrievers, and if you know goldens, you know that they are some of the most relentless and powerful chewers around. So I can’t give them almost any toy other than rubber stuff or it will be destroyed in a period of time that doesn’t make it worth it. One of them even figured out how to destroy a supposedly indestructible toy made out of kevlar! She was able to get into it through the seam, which is not kevlar ha ha. Anyway, I digress; I never even considered nylon chews because they suck! Usually. Usually my dogs in the past have lost interest with them in less than a day. I took a chance on these mainly because of the novel shapes, the fact that they give you two, and the low price. Both my goldens LOVE these! Not just for one day, but going on weeks now! I don’t know if it’s the flavor or what, but I will see them gnawing on one of them at some point every day. And they CAN’T destroy them (I knew nylon was good for that, but it was the “who cares” attitude of my previous dogs toward nylon that kept me away). Both the “ribs” and “steak” (quite clever) are a bit worn on the edges now, but they look like they will be around for years. You can’t go wrong with this product (unless for some reason your dog does not like the flavor, but the flavor seems to be what draws my dogs to them). I highly recommend this (these) as the most cost-effective chew toy I’ve ever purchased.

Great for larger dogs
Color: Grilled color
I think they were heavy duty and durable, but they were too heavy for my dog. The seller was excellent though!
