89' GMC Suburban, 20's in the front 22's in the back?

My truck is dropped 5" in the front and 6" in the rear, with air shocks on the back. It was like this when I bought it, and even with the max psi in the rear air shocks it still appears to be a little lower in the back. It has 20's all the way around now, but I'm thinking of either doing 22's all the way around (with possibly a taller tire in the back), or 20's up front and 22's in the rear. I'm hoping this will bring it up some in the back or give it a better stance overall. I've been trying to find a Suburban like mine with this setup or someone that has done this before to give me some advice before I pull the trigger on a set of wheels and tires. By the way, the 20" vision and tires are for sale in the pics...less than 900 miles on them. Thanks in advance!

If you've got the air shocks maxed out they may not be long enough...I had air shocks on my 85 when I lowered it and they would lift the back about 5-6in...

Did you have to switch out the shocks to raise it up some or buy longer air shocks (if that's possible)? I would like to bring it back up a couple of inches/a few inches to make it look less like it's lower in the back than the front. I'm hoping 22's all the way around, or 20's up front and 22's in the back would help.

Rim size won't affect the stance...it the rubber around them that will raise or lower it.....on the shocks I just got stock replacement air shocks for mine...
