Backspacing and Rim Width

[Lifted95X]

Does anyone know what the stock rims are....i'm trying to get an idea of how much more some eagle 15X8 would stand out. The guy at the tire place said that my truck...being a 4X4 explorer.....that with my tires....and the eagle 589's....it will rub....does anyone have these???

i've got the 589s 15x8 with 35x12.5 on them with 3.25" backspacing. i don't rub even at full lock. i still have the stock radius arm also. i know a couple guys hav 15x8 with 12.5 wide tires with 3.75" backspacing and they're fine too. my truck has a little wider stance also.
