The wheels pictured are absolutely the Firestone RH-5° widow makers.

What stopped the RH-5° was threat of government recall. The NHTSA and IIHS were well along with the recall effort when in 1972 the wheel companies agreed to stop selling them. Sales materials for Budd, Motor Wheel, and Accuride ceased their listings in 1972. It took K-H until 1976 to comply. Stu
