Black steel wheels and back spacing
 
Hey guys
I see allot of TJs with black steel wheels and I love um. my question is, what is the back spacing you use to order them ?
I have also heard that the steel wheels are much heavier then Alum wheels and hurt gas milage. is that true ?

thanks

Most of us run between 4.5" and 3.75" bs on our wheels, regardless of the material they're made from. This allows for a wider than 10.5" tire.

Steel is heavier, as well as a larger tire will add considerable weight. Factor in added rolling resistance for a larger tire and it does increase fuel consumption. Personally, I lost about 1.25 mpg's when I went from my stock Canyons with 31's to soft 8's with 33's. Everyones experience will differ according to their tire choice, since some are much heavier than others, and tread depth also affects things. Wheel size will also affect the weight gain, and gearing and driving style/habits/terrain are variables to consider as well.

i lost about 1 mpg when i went from the stock gamblers with 31's to 15" steelies with 32's. i noticed a slight drop in power due to the larger tire size/weight as well. the jeep had 3.73's and a 5 speed.

Do u prefer the 32s over the 31s? I want bigger tires but not sure what size to go I know I don't want 33s thought.. I'm debating on the 32s or 31s I want bigger but not too big. Can I get some advice? Please
