I'm currently window shopping for some new wheels for my Ranger. I want to stick with a 15" (currently running 31x10.5R15 tires). My stock wheels are 15x7 aluminum. I'm thinking about going with a 15x8 or sticking with a 15x7. What advantages/disadvantages are there in steel vs. aluminum. Steel are cheaper, and if dented can be hammered out. Aluminum reduces the un-sprung weight, but can break. What would work out better and give the best ride/performance. Thanks, Brian PS - Anyone know what the backspacing is on a stock 15x7 Ford Ranger wheel?
