kinroad 150 tire upgrade?
 

I'm wanting to go a bit bigger on my tire sizes and run 22 inch tall on all 4 corners. Right now it has 19 front and 18 rear. I'm looking for some advice on rim sizes in order to do this. Last I read I think I have 4-110mm bolt pattern on this thing. My plan is to run ITP delta steel rims 12x7 with a 2+5 offset on the front with 22x7 tires. On the rear the same delta steel style rims 12x7 with a 5+2 offset and 22x10 tires.

Any of you gurus that have tinkers with tires sizes see anything I'm figuring wrong? I do understand it'll loose some bottom end but I think I can tinker with it to make up for it and be happy with the extra ground clearance to ride around the trails on my property.
