yes first is width 2nd is sidewall height
so lets start off with tires.
225 65 17 is 28.52 inches tall
for a 22 inch tire if you did
265 35 22 front it is 29.3 inches tall
285 35 22 would be 29.85 inches tall
Your at 29 inches in front now with that 28.5 tall tire. Going to lets say the 285 35 22 would be a 1.3 in taller tire but would lift you up 1/2 the difference in height so about 5/8 of a inch the front would come up so you would be at 30 5/8 in front which would be about half inch higher in front than mine.
Now lets go to the rear.
Your at 27.5 with a 28.5 tall tire.
If you went with the same tire as mine would be 32.1 inches tall ie 285 45 22
So rear would be 3.6 inches taller which would lift the truck about 1.8 inches.. lets say 1 3/4
so your at 27.5 rear now and you would lift up the rear to 29.25 which is still about 1 inch shorter than your front with the same 22s.
The above can vary since diff manuf. use different variances but when I had 285 35 22 in rear and went to a 285 45 22 my truck lifted up 1.25 inches at the rear fenderlip which came out perfect.
So heres what I would do.
1) Get the djm lifting shackle (about 65 shipped)
2) Get your 22s and see the biggest tire you can stuff in the back of that truck with the wheel you chose. 305 45 22 would be the tallest wheel at 32.81 inches tall but due to the width you might have to roll the rear fenderwells.
3) Speedo will be off so might look into that but its prob off now anyway due to your tires not being same height as stock
4) Once you get it installed then see if you have to cut a little of the front spring. 1/2 loop should do the trick.
22x8.5 with 20mm offset and a 265 35 22 front
22x10 with a 20mm offset and 285 45 22 rear
or if you want to use same rim all around you can can do a 22x9 with a 20mm offset and a 265 35 22 front and a 285 45 22 rear
btw here is my pops truck
275 45 20 front
295 45 20 rear
I think rear was at 30 and front was at 30.5 im going to pass by there tomorrow again I can measure it for you
