Do you have 17" wheels now? If so, the OEM 20" wheels have 275/60/20 tires, which are 33" tall, so no lift typically is required for 33" tires. On the 05s, 33x12.5x17 tires will fit without leveling the front, or adding a body lift. But, if you wanted to do the body lift for looks - go for it.
If you wanted to go with narrower tires, then 285/70/17s are about 11 1/4" wide and 32 3/4" tall, and 295/70/17s are about 11 5/8" wide and 33 1/4" tall. The 285s are much more common, so the prices would be better.
Also -are you interested in AT or MT type tires? As an example onlinetires.com has 285s that range in price from $125 to $265 each before shipping for various AT and MT tires.
