A 1-2" body lift would probably be all you need to run the 305's, you may get some rubbing on the inside since the tires are wider. Spacers or new rims with different backspacing would take care of that problem though.

 

On the 'spacer' thing,what do you guy's think of them?

 

I've been using them on my WJ for almost 4 years now and haven't had any problems with them.
You do have to install them as per instructions and remember to check the torque when you rotate your tires. But that's just my opinion.

 

You need to include more

 

I'm running 33x12.5r15 right now, these rims have a 3.75 backspaceing and don't rub anywhere, I have had 285x75r16s with stock JK steel and 1.5 spacers, you will need to lift though, I am useing a 2.5 BB and all is good.
