I have a f150 and would like to some bigger tires on it. I have 275/55/20 on the truck now. What tires can I put on without getting bigger rims? Would I need a lift for 33 or 35 tires? What size?

ETA 2014 model

Year model of the truck is going to make a difference.

You have 275/55R20 on it now. UNless you changed the tire size from OEM.

If you're a 4WD and 09-14, you can get away with 275/60R20 with a teeny bit of rub on the pass wheel liner during U Turns and if you have a person in the pass seat.

15-18 should be the same.

Leveling with bilstein opens up lots of doors depending on how high you adjust. 275/65R20 (OEM Super Duty size), and 295/65R20 which is about all I'd go on a stock wheel.

If you want to go crazy, you can look at new spindles, springs etc.

Are The factory 20s 9" wide? I'd be alright rocking a 295-305 on that width. I ran 35-12.5-17s on an 9" wide rim for two sets of tires (70k miles). Never had any issues but doesn't mean I wasn't pushing the envelope.
