Help for clueless tire guy.

Question,
I just bought a set of used rims and tires for my 2010 tundra crewmax.
They have 33x12.5 r20 on them. The tires are very little tread left. I’m wondering if 33’s will fit stock..or if I need to level..also could I put 275x55 on this rim if I wanted too so I didn’t have to get MT’s and could get a set of all terrains..I use my truck a lot and will eat through MTs quick I think.

 

33” diameter should fit with stock suspension and wheels with stock offset (+50 to +60). But the 12.5” width may rub the upper control arm or skid plate on stock offset wheels. With lower offset aftermarket wheels, they may rub the little forward flap in the front fenderwell.

 

Just an update...33’s fit stock with no rubbing or touching anywhere.
