Sand tire rims

[Moose Master]

Bought some system 3 - 360 tires 32x 10 x15 and 32x12x15 for the rears. getting bead-lock rims but where I'm buying them there asking about offset and bolt pattern. So to get this right any suggestions? Front tires are 10 wide and rears are 12 trying to avoid rubbing The rims are also system 3 They are having Memorial Weekend sale and I want to pull the plug and get them.

Bolt pattern is 5 on 4.5
OEM offset is 6/1 but especially for running sand tires I’d go 5/2 or 4/3
