Goodyear 450-21 All-Weather Balloon Tire – Blackwall (BLK)

The Goodyear 450-21 All-Weather Balloon Tire – Blackwall is a meticulously reproduced tire that captures the look and feel of Goodyear’s groundbreaking balloon tire technology from the 1920s. Featuring the original diamond-block tread pattern and classic black sidewall, this bias-ply tire delivers authentic styling and performance for early vintage vehicles.

Originally designed to provide a softer, smoother ride on rough roads, balloon tires like the 450-21 became a popular upgrade in the late 1920s for improved comfort and handling. This size was commonly used on early Fords and other automobiles from the era, and remains a staple for accurate restorations and antique vehicle displays.

Key Features:

  • Size: 4.50-21

  • Construction: Bias-ply balloon tire with vintage ride characteristics

  • Sidewall: Blackwall (BLK) for authentic prewar styling

  • Design: Classic Goodyear diamond-block All-Weather pattern. Manufactured using the Goodyear original molds, ensuring a period-correct sidewall and tread

  • Application: Factory fitment for 1927–1931 Ford Model T and Model A, as well as other early 20th-century makes

  • Proudly made in the USA

Perfect for concours restorations, museum displays, or driving-era authenticity, the Goodyear 450-21 All-Weather Balloon Tire – Blackwall offers a true-to-period appearance with the ride quality and charm of America’s earliest motoring days.

Tire Cleaning & Maintenance
For tire cleaning, we recommend using an SOS pad along with soap and water. This method works for routine cleaning and effectively removes the protective blue layer from white walls and raised white letters on your new tires.

DO NOT use any chemicals to clean your tires; this can cause the tire’s white walls and raised white letters to turn brown. If you use chemicals to clean your tires and your white walls turn brown, you can not make a warranty claim.

Note for the 1st Generation Camaro only – Read Carefully

14” Goodyear Tire Fitments
Goodyear Polyglas tires were first used and going forward in April of 1969. For Goodyear RWL fitments for vehicle build dates beginning in April 1969 through October 1969, use Goodyear Polyglas SKU# CB5KL. November through December of 1969, a running change was in place with Goodyear Polyglas installations. Thus either the CB5KL or CB5KJ may be used. As you can see, this encompasses the first half of the 1970 build year. Prior usage from 1967 through March of 1969 was the Goodyear Speedway Wide Tread series.

15” Goodyear Tire Fitments
The Z28 cars of this generation are well-defined. 1967 735/15 Red Line SKU# CBBMV. 1968 & 1969 Goodyear Speedway Wide Tread GT E70/15 RWL STK# CB3EX. 1970 – see running change note above. F60/15 RWL STK# CB4GF or CB4GG, depending on the vehicle build date. The F60/15 RWL STK# CB4GG was used from January 1970 through the end of first-generation O. E. bias fitments.
