Goodyear is greening its newest ElectricDrive GT tire that’s accessible as aftermarket alternative rubber for the Tesla Mannequin 3—with carbon black that doesn’t rely upon the combustion of fossil fuels.
The brand new tires as an alternative use carbon black from Monolith, made by way of methane pyrolysis and never requiring combustion, Goodyear says. Monolith’s methane pyrolysis course of as an alternative splits the methane molecule into carbon and hydrogen, utilizing renewable electrical energy.
Carbon black is a vital ingredient in tires for its tear and abrasion resistance. Due to their added weight and better torque output, EVs want totally different tires, too. The ElectricDrive GT line, particularly, has a built-in sound barrier for highway noise, which is usually additionally a difficulty in EVs, and it claims a quiet trip—although in keeping with Goodyear it’s an “ultra-high-performance” all-season tire.

Goodyear didn’t say the place it procures the methane for the carbon black on this course of, or state whether or not this course of truly reduces the carbon footprint of the ensuing product. Nevertheless it did notice that it’s investigating with Monolith the potential expanded use of carbon black made out of methane derived from waste sources.
In 2019, Bridgestone claimed to be the primary tire firm to make tires with recovered carbon black from different industrial processes, and final 12 months it stated it’s taking a look at bringing pure rubber again into tires. Goodyear in a 2022 confirmed an indication tire manufactured from 70% sustainable supplies, then only a 12 months later, this January it upped the ante to 90%. The newest tire thought of carbon black from 4 totally different sources. Each manufacturers plan to go 100% renewable or sustainable, however these previous few p.c would be the most difficult.

To this point these are solely the alternatives of firms concerned about greening their pictures and lowering their carbon footprints, however rules may feasibly cowl tire compounds sooner or later. California is contemplating effectivity requirements for alternative tires, although it’s basically a matter of assuring sure fuel-saving rolling-resistance numbers.
