Are these pizza cutters?

Considering going from 275/65/18 stock tires to a 265/70/18 tire, both setups on stock suspension and stock wheels.

I see no problems going this setup.
2018 Tundra SR5 DC 4x4 with Offroad package.

Any input is appreciated.

 

That’s what I did. Little taller, little skinnier. I went with Nokian Rotiivas. I think it looks better, and I’ve always found a skinnier tire to do better in mixed winter conditions. I work a long ways from home and have no choice but to drive when it’s shit outside. On my old tundra, 245/75r16 ALWAYS outperformed 265/70r16 or 265/75r16 in snow and slush and whatever crap was on the road. if I could have easily gotten 255s in an appropriate height, or even 245s, I would have.

 

The reason why is exactly what @bjp said. Where I live there are often slushy conditions during the winter months.
I'm not going for looks but effectiveness. Sometimes function over form wins.

 

This is the Best setup for looks and performance!

 

Thanks for the feedback!
