I bought a 4 door 68 Coronet for parts ( traded the running 318 for a paint job I never got) 300 in change! Had original bias Ply tires... not sure about the air though...I am sure,.after I put 4:56 gears in my 68 383 4spd 'Net, and terrorized the neighborhood for a week, those tires were completely ruined, and I went back to 3:55s and 2.5" pipes w/ Flowmaster 40s. They were 35 bucks then... hey, it was a fun youthful experience, I guess... those poor tires tho
