Upping tires

Hello all, Currently have 275/65r18 on my 2019 tundra Ltd 4x4 off-road trd (factory upgraded). I'm considering adding fender flares, 2" spacers, and was wondering if anyone can tell me upping my tires to 305/70r18 would be an issue. I don't wanna do a lot of cutting or removing stuff, leveling and or lifting, as I know the "true" 35s i.e. 35/12.5r18 does not quite fit with these trucks unless lots of mods are done to it. Asking y'alls for help.

 

Adding 2 inch wheel spacers will limit the tire size, especially if you are unlifted, as you are changing wheel offset, so tires can hit front bumper or body mount area, depending.

If you are stock, unlifted, 285/70-18 (34 tall) tires work on factory +60 offset wheels with no issues. Less offset or wheel spacers could have you rubbing things.
275-70-18 is popular size, 33 tall, and would work better with spacers or less offset wheels on a stock height truck.

Tons of info on setups in the wheel tires forum, as well as 2.5 gen forums.

305/70s can work, they are wide so need less than stock offset and will likely need at least a level kit to clear, removal of mudflaps and possibly more to fit.

 

I appreciate the feedback
