47-55.1 s10 ZR2 axle - what wheels/tires are you guys using?

[73kay]

Hey guys,

I have a 53 and scored a ZR2 axle with drum brakes 3.73 post etc. It's 63 inches wms. I am piecing together threads to find out what tire/wheel specs I need. Today I have some smoothies 15x7 with 3.25 bs and rubbing. The rear suspension is TCI leaf spring kit that is 4in drop + 3in drop blocks. I am rubbing as it stands. What wheels/tires are you guys using with a ZR2 axle and have a lot of drop? I am looking to stay 15in wheels.

My thought so far is that I need new wheels with at least 4 or more backspacing and some positive offset. Otherwise I will have to start trimming the fender lip and/or switch to a narrower tire like a 225x75.15 (8.85 in width vs 9.25 of the 235x75x15).

Hope I am missing something simple here, below is some nerd math if that helps.




bed box is 50in wide
backspacing for wheels needed is 4 inches (4 x 2 for both sides = 8 inches)
ZR2 is 63
63-8 = 55 inches (2.5 in of the axle sticking out each side of the box)
need clearance to be ~1 in on both sides of the fender, so need to bring the wheels in towards the bed another 1in at least?
