Ok so I am new to these forums and really do not know a lot about cars. right now I drive a 2000 grand cherokee and I would really like to buy this

I would like to know what the biggest rim/tire combination I could possibly fit under this ride. I would really like to have 20's, and really ride rims in the back for traction.

 

you mean wide rims?? the largest I have seen in width were L60's I have L50's on mine to keep the tires inside the wheel wells. don't put 20's on it thats the stupidest thing I've ever herd.
