On this article, I cowl Goodyear’s bulletins from the CES 2024 present and get some solutions on why we are able to’t but purchase retreads for our vehicles.

Goodyear show at CES 2024

ElectricDrive 2

ElectricDrive 2. Picture from Goodyear press launch.

Goodyear’s ElectricDrive 2 tire is an all-season tire particularly designed for electrical autos (EVs). It options an uneven tread sample for dependable dealing with in each moist and dry situations, in addition to SoundComfort Know-how to make sure a quieter experience. The tire is made with no less than 50% sustainable supplies, together with soybean oil and rice husk ash silica.

In comparison with the earlier ElectricDrive tire, the ElectricDrive 2 presents improved rolling resistance, which reinforces effectivity and vary. It is usually designed to supply a longer-lasting tread life to maximise drivers’ EV efficiency. The tire is out there within the US beginning in Could and is available in 17 sizes to suit in style EV fashions such because the Tesla Mannequin 3, Tesla Mannequin Y, Tesla Mannequin S, the Ford Mustang Mach-E, and the Chevy Bolt.

Richard Kramer is on the correct.

Within the interview, I requested the pointed query of what do you quit in going with this tire? Richard described that the tire industry long thought of a triangle of sturdiness, traction, and rolling resistance. It’s troublesome to enhance a kind of with out impacting the opposite two attributes. For instance, in order for you most traction for a racing tire, you have to quit some sturdiness and/or rolling resistance. If you’d like excessive sturdiness, you have to have a tough tire and it must quit some traction, particularly in winter situations. For the ElectricDrive 2, Goodyear balanced all 3 rather well to provide wonderful sturdiness and rolling resistance and all-season braking and dealing with. He did admit that this isn’t a high-performance tire, so in order for you the absolute best summer time traction, they produce other tires for that, and for the most effective winter traction, they’ve winter tires that stay mushy in chilly climate.

In abstract, the Goodyear ElectricDrive 2 tire is an eco-friendly, high-performance tire tailor-made for electrical autos, providing improved effectivity, vary, and sturdiness. For extra particulars, see the full announcement here.

Creating Superior Tire Intelligence Applied sciences With Goodyear Sightline

I used to be initially fairly skeptical about integrating ZF tire monitoring sensors with Goodyear Sightline and working with TNO to cut back hydroplaning on moist surfaces when driving on worn tires. First, I’ll summarize the bulletins. Then, I’ll describe the simulation that impressed me.

The important thing quote from the ZF announcement is under:

By analysis, digital simulation and real-world testing, Goodyear and ZF have recognized the potential of an built-in answer in enhancing automobile efficiency and security. Lowering the danger of hydroplaning, the Goodyear SightLine answer is able to detecting partial hydroplaning early and presents suggestions for optimum velocity to reinforce automobile management. Furthermore, when heightened hydroplaning severity is detected, outfitted with tire intelligence information, the cubiX software program is designed to instruct the chassis actuators to use corrective measures, stabilizing the automobile.

The important thing quote from the TNO announcement:

The ABS is a vital security part in trendy autos designed to assist the driving force preserve steering management whereas braking. By collaborative analysis and testing on a bodily take a look at automobile, Goodyear and TNO successfully showcased that an improved ABS, outfitted with details about the tire kind and traits resembling put on state, can doubtlessly improve total system effectivity and cut back braking distance by as a lot as 5.75 toes.

I get a while on the Goodyear simulator. Right here I’m poorly navigating a slalom course.
I needed to cease immediately when a deer appeared.
Brake distinction with and with out the improved ABS software program was dramatic.

The Final In Reuse & Value Saving — Retread Tires

I’ve been listening to about retreaded tires since I used to be an toddler, since my father purchased me some Bandag inventory (I now not personal any). Three years ago, I wrote about reducing tire costs, and once I bought an e-mail final week providing me the possibility to interview the CEO of Goodyear tire, I jumped on the probability. Though I believe that was the very last thing he anticipated to be speaking about that morning, he didn’t miss a beat and answered all my inquiries to my satisfaction. Earlier than I get my questions and his solutions, let me offer you a little bit of context.

After I requested Grok to provide me a abstract of the market, it did an excellent job:

Retread tires, often known as remolded or recap tires, are a cheap and environmentally pleasant various to buying new tires. The method entails taking a worn-out tire and changing the worn tread with new tread, permitting the tire for use once more.

Retread tires have an a variety of benefits, together with:

Value-effective: Retread tires can prevent as much as 50% of the price of a brand new tire, making them a extra economical selection for a lot of drivers.
Environmentally pleasant: Retreading tires reduces the quantity of waste that goes into landfills, in addition to the quantity of vitality and assets wanted to provide new tires.
Excessive-quality: Fashionable retread tires are made utilizing superior manufacturing strategies and high-quality supplies, leading to a product that’s simply as protected and dependable as a brand new tire.

Regardless of these advantages, there are some myths and misconceptions about retread tires. Some folks imagine that retread tires usually are not as protected or dependable as new tires, however that is merely not true. Retread tires are topic to the identical security and efficiency requirements as new tires and are simply as protected and dependable when correctly maintained.

In conclusion, retread tires are a cheap and environmentally pleasant various to new tires. They provide the identical security and efficiency as new tires and are an incredible selection for drivers wanting to save cash and cut back their environmental affect.

Subsequent, I requested Grok why they’re used on vehicles however not vehicles and I bought some good causes:

Retreaded tires are generally used on vehicles and different business autos for a number of causes.

Value-effective: Retreading is a cheap approach to prolong the lifetime of a tire, which is particularly essential for big business fleets that use a excessive variety of tires.
Environmentally pleasant: Retreading reduces the variety of tires that find yourself in landfills, serving to to preserve assets and cut back waste.
Efficiency: Fashionable retread tires are made utilizing superior manufacturing strategies and high-quality supplies, leading to a product that’s simply as protected and dependable as a brand new tire.

Nonetheless, retreaded tires usually are not generally used on passenger autos for a couple of causes.

Security issues: Some folks imagine that retreaded tires usually are not as protected as new tires, though this isn’t supported by the proof.
Lack of understanding: Many individuals are merely not conscious of the advantages of retread tires and should not take into account them as an possibility.
Availability: Retread tires usually are not as broadly out there for passenger autos as they’re for business autos.

In conclusion, retreaded tires are generally used on vehicles and different business autos as a result of they’re cost-effective, environmentally pleasant, and carry out simply in addition to new tires. Nonetheless, they aren’t as generally used on passenger autos because of security issues, lack of knowledge, and availability.

With that as background, I requested him about retreads from a producer’s standpoint. I paraphrased his reply under:

  • They’ve a really profitable retread program for semi vehicles and a considerably much less profitable one for vehicles.
  • They’ve studied it in depth for the price range shopper market (assume 10-year-old Honda Civic) and the problems are:
    • Buyer notion of high quality. Though high quality retreads are as protected as new tires and don’t fall off, folks have seen poor high quality retreads up to now fall off a semi truck and lay on the aspect of the highway. Nonetheless, this may very well be countered with guarantee, training, and promoting.
    • The semi vehicles all use the identical dimension tires, so it’s straightforward to make just some sizes to cowl your entire market. Shopper vehicles and vehicles use lots of of tire sizes, so the quantity of every of these sizes is just too low to handle the method economically.
    • Sellers have discovered patrons for used and worn tires at the moment, so that they must compete for the previous tires and never simply get them without cost.
    • Due to that, they might solely be a bit cheaper than new tires, and with the notion of poor high quality (not correct), they wouldn’t promote effectively at a small low cost to new.
    • That being stated, a big fleet that had an ordinary dimension (like Hertz or Uber that has many Teslas, even after the latest information they’re slicing again) might save some huge cash by placing retreads on their autos.
    • If Tesla (like with the Mannequin Y or Mannequin 2 or robotaxi) or others, like BYD, promote hundreds of thousands of autos with the identical tire dimension, that may permit them to supply retreads in sizes which have hundreds of thousands of gross sales.
    • If there have been much less proliferation of sizes and kinds of tires, the entire trade would develop a market for the worn tires to assist retreading and enormously enhance the sustainability and price of alternative tires.

Conclusion

It was nice to listen to in regards to the new ElectricDrive 2 tire. I discussed that at the moment, it’s adequate to have a common EV tire, however sooner or later, they’ll want an EV excessive efficiency, EV price range, EV lengthy life, and EV winter tire. He agreed. Because the market develops, they’ll proceed to launch merchandise to satisfy rising wants. The simulator actually confirmed me the worth of the sensors and software program that Goodyear introduced on the present. Will probably be attention-grabbing to see the place they’re adopted. I realized so much about retreads and I shall be seeking to see if this develops first for the fleet market and later for the buyer market if Tesla and others are profitable at promoting extra autos with the identical dimension and sort of tires than the market does at the moment.
