I recently got a 3 inch sky jacker lift, 31 x 10.5 15 BFG All terrains (on my 15 ecco stock rims). Want to make it tougher looking (didn't have money for 33's and MT's don't make sense for me for mpg) Thinkin about black rock D type rim (15x8 probably) or les schwab D type rim but I am not totally sold on the black rims...kinda like the silver on silver and not steel...Also on a budget. Will spydertrax spacers work to pop my existing rims out to either 3.75 or 4" backspacing (if so what size would I need). Or do I need knew rims to get tires out so it makes a difference? Thoughts...
