Tire size and lift for 2010 Tundra

I have a 2010 Tundra Crewmax 4x4.
Getting ready to switch from 18" to 20" wheels and need to know how big of tire I can do with no lift and how big with 3" lift. I know nothing about this stuff. Doing this for my son.
Any info will be appreciated. Thanks.
Will 33's work with just leveling?
Will 35's work with 3" lift?

 

Stock tires are 32's so no real change with 33's. 35's will depend on the lift used and wheel offset. Going from an 18 to a 20 is going to kill the mpgs.

 

Thanks for the info. Mpg's has always sucked so not worried about that. Trying to keep the kid happy without spending to much money on it.

 

I have 275/65R/20 tires on my 2010 without a lift and it definitely cut my MPG, mainly on the highway, down about 1 MPG.

Some damn nice pickups here just use the search tool..

 

Thanks.

 

You definitely in the right place.......... to learn how to spend

 

Haha.....no doubt! Trying to keep it simple, my son doesn't want anything that stands out to much just sets a little taller. He's not in to the big stuff and I am for sure not.

 

I do have tire rub if I turn the wheel all the way one direction or the other.
