I just bought some 16x10 -38 with 4" backspacing all the way round and just wanting to know if anyone was running these???? With pictures????I have seen some pics of 15x10..... And I'm running 205/50/16 tires

 

I also have a set of MRR HR3 in 20x8.5 35mm and 20x9.5 40 mm

 

I'd think they fit but they will be in contact with your fenders and bed side if your dropped enough 10 inches can be done on these trucks just depends on offset and drop before contact becomes a issue

 

crazy, 10" width with -38mm offset or +38mm offset?

-38mm offset means that'll stick out of your fender a good 2", roughly.

 

I want to run 4x4 fender and 4x4 fender flares but I hope it sits hellaflush(praying)

 

I give up.

 

What the Max back spacing with no rub when full turn 5" or "4.5
