leveled rims and tires questions

[mblake08]

hey guys
headin to order my rims and tires this upcoming weekend. i have a 02 4x4 so im doing the torsion key crank. already have my shocks. now looking for rims and tires.
i cant decide between 18' or 20's.
i have read i can go up to 35's but i think im gonna stay near 33-34.
the 325 60 r18 are 12.79 inchs wide and 33.35 inches tall. what offset am i gonna need to run around 12.5 inch wide tires with out rubbing or trimming.
the rim size dispute between the 18 and 20. i want bigger then 17 rims but im not sure if 20's with 33's wont have enough tire. im not to crazy about the low profile look. im also looking at the 325 65 18's which r 34.63 inchs tall same width. i dont want any rubbing and no trimming and i dont want to have to crank the torsion keys too much for the cv angles.
tires-any POV's between nitto terra grapplers and toyo OC2's possible the falken wildpeak a/t's or the goodyear silent armours.

so what offset and/or backspacing will i need and what tires with no rubbing or trimming
can anyone help me with these problems?

thanks guys

If you do a 9" wide wheel I would look for something with an offset close to 0. I think the highest you can go and still clear would be about a +10mm offset. Now that will change if you go with a narrower or wider wheel.
Depending on the look you want, you can go lower in the offset but it will push the wheel out

thanks. so 0 will work. so obviously if the rim is -12mm it should be fine.
i want my tries to sick out maybe 2 inches.

then -12 is what you want

yes -12 offset will be good and will push your wheels and tires out like you want.
