Run 305/55r20 on stock rims with level?

I wanna keep 33s and these look really beefy for 33s. It should be possible to put them on factory RST 20" wheels. I think they are 9" wide. However I am sure they will rub unless a spacer is added. How much spacing would be needed to make this work with a 2" level? Also is this a really bad idea for towing and load hauling?

Looking forward to replies...

I saw that folks on the K2 forum did it. Usually they needed a 0.25" spacer to make it work. All needed significant leveling. I think that with these T1s you can fit a lot more tire with a lot less lift than the K2s. I have a feeling it could be made to work.

Im curious what mounting a 305/55/20 on a 9" rim does to its overall height. Does it make it taller since it is squeezing it? Or shorter or no effect?
