Personal taste gets it the way of recommending a tire.
The best thing to do is, do your own research.
Determine what rim you have.
Select which tire that will safely fit.
Search the Internet for a picture of the tire & rim combination and see if it is to your liking.

About 1969 started radials in the USA then 1982 cars and some trucks were standardized with radials.
Also modern rims do not have the clips needed to hold original hubcaps.
