What is the intent for the car ?? stocker ?? street bruiser ?? street/strip car?? drag car ?? pro-touring/Resto-Mod ??... we need more information... The 2nd gen 1968-70 Chargers, they have very large wheel wells, they can handle allot more tire than what they come with... IMHFO the tiny winney stock 14" diameter wheels look like little roller skate wheels... If your not worried about 100% OEM or Factory correct crap, then I suggest put 15's or up-to maybe 17" diameter wheels on it, you will like the look of the wheel wells, much better tire selections & looking "filled up" & size approriate, somewhat much better than with the tiny winney OEM original 14"er's do... You can get the stock looking wheels even in the Magnum 500 or Ralleys, in larger diameter if that's the somewhat stock appearing type look you want... Wheels are such a personal touch on a car, "it's like jewery everyone likes what they like" & to each their own opinions... You can easily go with 8"-11" wide & 13" of girth & 29" tall in the rear of most 2nd gen B-Bodies, with the proper offset/back-spacing & 7"-8" wide wheels in the front with out to many issues... It really depends on what you like... BFG's are good tires, I use them allot...
