Well originally it most likely had bias tire's and about 1'' whitewall with impala full wheel cover.Just saying!!!!! ?
I wont disagree that the radials drive better but if the front end is rebuilt and in good shape the bias will be ok. And in my opinion the cars just look better with the bias tires. 50 years ago we drove these cars over a hundred mile an hour on bias ply tires and thought nothing of it. Actually most of the time I was on recaps!!
x2Wait till you see the cost of those obsolete bias ply things.
