275/65 R18 vs 305/60 R18

I have a 2019 extra cab with Trd offroad package.
I don't go offroad but have a 1400 foot long dirt driveway and am almost at the end of the factory tire life.

I need tires that can get me through deeper snow.
Am I better off with factory tire size or the 305/60 R18 and would these require trimming of anything if I went this size?

Thanks all

 

275/70-18 is a great size, beefy, fits stock and lifted truck no problem and there are tons of nice brands/tires available. I would choose that size over the 305s personally.

Check out the wheel/tires forum, there is a thread dedicated to 275/70-18s so you can view pages of pics of trucks from stock to lifted, factory and aftermarket wheels, etc.

275/70 is 33.4ish tall, just a hair over 11 wide vs stock size of 32inches tall and they fit a stock truck with stock wheels no problem, no rub. They will be E load and heavier so expect a small hit on MPG, which will be the case when installing heavier tires or tires will more aggressive AT tread.

I run that size, ran it stock and kept the tires with my 2/1 lift and they look great.
