Goodyear offers an aluminum core bead for use in aviation tires. The patented light weight alloy bead core using aluminum results in weight savings. The traditional construction of the bead has a steel center wrapped by strands of high tensile wire. Goodyear has found a way to replace the steel core with aluminum. The tire with this innovation, H37.5x12.0R19, will be fitted on the Gulfstream G650. The weight savings on this tire equates to 3 pounds per tire. Goodyear introduced the first airplane tire in 1909, and since then, has continued to innovate in aviation tires. For more information visit www.goodyearaviation.com.
