Need 22/24 tires help

[The Big Green]

I have a bodied 95 Chevy and I had two 22's and did a 6 lug swap so wheels are on the front. They are 22x9.5 with a 255/30/22 and I made the mistake and got a wrong width tire for it. The rim lip hangs out so far I can't tell there's a tire from the right angle and when I lay the camber this thing has the lip about touches the pavement, may even touch lol. I think it'll break the bead at any moment. I can't get two more 22's because they stopped making them so I'm going to the 24 and doing 22/24 combo. Here's the part I can't decide. If I do say a 275/30/24 then I can't really do a 285/30/22 like some guy told me because the tire heights will leave me taller up front in tires sidewall height. Basically I have 22x9.5, and I'll have 24x10 on back. I touch firewall hard on the 255/30/22 but if I relocate the wires on the firewall I'll be ok. I have 28in dia worth of room in the front and the rear I have no clue but I need my tires to match and not have the front wider and taller and keep the staggered look. The rear I have a stepside so with the rallies and 235/60/15 I'm already eating my fenders but I'm bodying a fleetside bed so I have no idea how tall I can go there. I have a 10in wheel with +40 or 7.1in bs.
