22" wheels and don't really like

[mig1980]

Hi there everyone. I purchased a set of 22" Asanti wheels. They are 22 x 10.5 all around with 285/35/22 tires. I mounted them today and the rear don't fill up the wheel well as much as I would like. I don't understand how the 20" wheels that I had on filled up the wheel well so much more. They were 265/40/20 in front and 315/35/20 in rear. I realize that the tire is wider on the rear from my 20" wheels than it is from my 22" wheels but they are both 10.5 in rear so I don't understand why so much different. I guess my question here is, would I be able to get a wider tire in the rear fill up the wheel well or is there a difference in the wheel width of the 20" (4.8is style) wheels than the Asanti wheels?

Thanks in advance to anyone who chimes in.
