Hello, I have a 2018 F150 XL regular cab long bed FX4 4wd

It has the original Goodyear Kevlar A/T tires at 245/70/17 which is about a 30.1 inch tire

I am looking to get BFG A/T Ko3 or maybe Duratracs or similar and want higher sidewall profile for softening ride, and airing down off road

I have the stock XL 17" steel wheels.

Looking for inputs on possible higher profile tire sizes.... like 32 or 33 inches

Don't want a lift, don't want rubbing
Don't mind a little mpg loss, don't mind a little torque loss

thank you

Is your truck an HDPP? 245/70r17 is normally the 2wd size. What load range are the tires on your truck?

 

not sure on HDPP but here is the spec from the window sticker

 

Ah yes.

Your tires are LT not P metric.

If you can, go take a look at them. Find what the max PSI is and see what the load rating is (LT come in load C, D and E).

You need to use the same load rated tires or a higher load when replacing.

 

They are LT rated P metric sized and have a load rating of E
It says that on the window sticker listing
Given I tow 7000-8200 lbs regularly I would stick with E

Curious if this tire will fit, load E 285/70/17 32.8 dia.

With your stock wheels, you should be able to fit the LT285/70r17E without issues. It’s about a 32.5” tire.

 

Visuals for the win!!

 

very nice computation tool
Ya, I figured a little more than 7% torque loss so that is cool that its not as bad

ok I will order and try the 285/70/17

thanks Folks

 

Seem like a regular question but as it's for a regular cab I'll add 2 cent's in.
My son's all stock 2019 4wd on Nokian Outpost 285-70-17 116T SL tires@32.7 inch diameter 46+ pounds each. Had them 2 winters they are quiet and grip good in snow.




My 2017 RC has a near 2 inch level 2wd on Nitto G3 116T sl, 48 pound 32.75 diameter, on 0 offset wheels. 7 mouths old grip dry/wet/snow ride well and quiet real similar to the Nokians.




Both fit without trouble, Sam's lost 1-2 MPG, mine are still in limbo for MPG we are still on winter fuel and I am dialing in my speedometer for accuracy. No noticed power loss both are 2.7s my XL came stock 245-70-17 Sam's XLT stock 265-70-17s. You should have no problem with this size and I think even larger in diameter. KM
