What is meant by a "correct" width?
Whitewall tires were not an option on Chevrolet trucks in 1953.
That is why some people above are saying that if you want whitewalls, choose any width that appeals to you. However, no matter what you choose, it will not be "period correct" for a truck - it still might look good - to your tastes.
Maybe "correct" (in the original posting) refers to the size of the white wall on a '53 automobile. Coker could help you with that. In addition, it might also be "period correct" to have other-colored side walls (they were available in the '50s and I think someone posted that they are still available).
