TC, "period correct" WOULD be the more correct statement for sure. Going on the fact that replacement tires were inevitable we can all assume that some truck owners would in fact decide to replace worn out factory tires with "period correct" whitewalls. My point was, that 60's era 1 inch whitewalls were not available in 53. My 59 currently wears four year old 1 1/4" Firestones which are definitely not period correct but fit in the budget during that stage of the resto.
