Can someone help me out PLEASE?!?! Wheel offset question

My buddy works at a discount tire, and can get me pretty good deals, plus there is a promotion going on right now making the rims and tires pretty cheap. The tires I’m looking at are the Kenda Executioners. I have seen one person with 8inch wide execs in the front and they said they would have gone 10 in the front if they could do it over again, so I’m looking at 10inch in the front. What I’m wanting to put on is 25x10x12 in the front, and 26x12x12 in the rear. I am REALLY wanting the Vision Lock Out rims, which are 12 inch(tall) rims, and come in 7 inch and 8 inch wide. The 7 inch has an offset of 4+3, and the 8 inch is 4+4. I was told by someone else that I need an 8 inch wide rim for a 10 and 12 inch tire. First, is that correct? And second, would 4+3 or 4+4 work? I really do NOT want spacers at all. Any help is EXTREMELY appreciated!

Thanks guys!
