Well, this was a rather long delay. Sorry about that.
Brake lines, inner fender flare, chains smacked about on the control arms etc etc.
With stock wheel and tire size there just is not enough clearance. I have read about some folks ( as mentioned ) who have made it work using off set rims and or spacers. What I have found is that with some weight in the bed of the truck and a quality set of rear chains( V bar or other studded type ) That there is not a lot of places one can not get in a stock tundra with 4 wheel drive and good rubber.
More than one time I was working out in the high desert of utah mid winter and pushing snow that was grill deep with our fleed tundras. Mind you, Utah snow is light and fluffy but still. It was impressive performance. If you are looking to go snow wheeling, you will surely find the limitations of the truck. Having a set of rear chains to get back off the mountain, or up it for that matter when chain control is in effect, or a nasty storm has blown in is more than enough to get you where you need to be.
