Just bought a F150 and wanted to upgrade tires with out changing wheels. Just a stock 2016 fx4. Ecoboost. the better half drives it so not putting anything aftermarket on it besides a step up in tires

I have a 2016 4x2 with the 18" Sport package wheels and replaced the original tires with 265/70 Falken Wildpeak ATs. They look much better and don't rub. I am confident that the 275s that are on the 4x4s have enough room for the same 70% ratio (my rim was just not wide enough - missing .5" and I didn't want to replace them).

You're welcome. I'm in the same situation - the wife drives the truck and I drive my Jeep :-)

The 33s fill the wheel well nicely and I didn't want to mess with things. I'm sure that small lift and wheels with less backspacing will allow larger tires without too much work.

If you go 33s do you gotta change wheels?
The size that I run are 33s on the original rim (see photo). You will have to look up your rim though, there are differences in the width. Maybe yours is a bit wider than mine and you can run a wider tire.

I have a 2015 and 33” BF Goodrich KO2s fit fine. With a 2.5” level and spreading the crash bars I’m able to fit 35” tires with zero rubbing.
