I have had a few early jeeps over years, 3b, CJ6, and early CJ5. Unless you have huge forearms or plan to upgrade to power steering you want to find a narrow tire. We call them "Pizza Cutters"
My CJ6 had no power steering and at the time BFG made a 32 or 33 in by 9.5" wide all terrain and they worked pretty good on the stock rims with a lift.
