Default 2018 F-150 Wheel Tire help

Hello All,
I'm JP, I just joined this forum. I recently got a 2018 F-150 XLT Sport 4x4. As with every vehicle I ever own I began looking into mods I wanted to do and came upon the wheel and tire selection and hit a wall. I have decided not to "lift" the truck but instead get a leveling kit for the front so I can put 33s on, not for any real reason other than looks. That is as far as I have gotten, now I have more questions than answers. I poked around on the internet and found some of the wheel specs 87.1 mm center bore, M14x1.5 threads, and 6 x 135 pattern. Now's where I need help.

I Have 20" wheels on the truck (factory set up), I'd like to move down to 17" or 18" wheels to maximize the sidewall.

What would be a good size 33" wheel tire combo for my truck with 17" or 18" wheels (wheel width, offset, and tire size would be appreciated.

JP

What tire sizes will fit is going to be offset dependent, so you should choose your wheels first unless there's a specific tire size you want to run. As for what offset to get, that's a matter of personal opinion and availability based on wheel choice.

For offset I’m not sure, only because I don’t know the F150 offsets well. What I’m looking for is a primarily a flush fit I’m not planning on fender flares so don’t want to poke much if at all.

The stock wheel's offset is +44. For a flush look with a 9" wide wheel, you'll want a +18 to +25 offset. Going with a 275/70R18 (33x11") will give you the most tire options.

Side note: Going over a 65 sidewall forces you into LT rated tires. They tend to be relatively heavy, cost a bit more, and have a harsher ride, but are more durable. If you don't need/want the added durability, you may want to consider a 20" wheel with a 275/60R20 (also 33x11") tire. Going to a 275/60R20 gives you a HUGE selection of tires, with many of the P-rated ones costing about the same or less than their 18" LT-rated versions.

Yes, either a 2” or 2.5” leveling kit.

Default 2018 Tire sizing help

I see a lot of sizes flying around for leveled 2018 F-150s and am looking for help. I have a 2018 with stock 20" rims and a 2" Level and am looking at 33s or 35s depending on wheel rub. Bfgoodrich KO2s if anyone has experience please share.

Thank you

35s will rub the UCAs on a 2" level. I would look at a 295/60R20 (34x12"). IMO, it's the perfect size for a 2" level, and doesn't require any cutting/modding to fit with stock wheels.

Thank you for the response, I will look into it. I cant remember what I had on my 2009. I should've taken a picture of them before I sold it. But I digress. I will research into this. Does anyone have pics of this setup?
