if i have 4.56 gears, what size of tires can i run?

any size tires you want...... 33s will probably be the most optimal and 35s will be ok as well

Here's a good calculator for you: http://www.4wheelpartsperformance.com/html/calc.php

I have run 33s, 34s, and 35s (true 35" tire) with 4.56s. I have a 5 speed manual trans with the 4.0 V6 motor. I consistantly started out in 2nd gear with the 33s and 34s. I only used 1st gear on hills or offroad. Now with the 35s, I still start out in 2nd when flat or slightly down hill. It seems like the perfect setup with the 35s cause my truck is also my daily driver. My rpms are about 2800 on the freeway @ 75mph.

If you have an auto, then 35s will be perfect with the 35s. Your rpms will be slightly higher then a 5 speed. The auto will have a lot more torque and plenty of power with 33s or 35s.
