Just bought a new-to-me 2014 4x4 F-150 - SCAB, 3.5 EB, 3.73 gears - with 16.4k miles on it.

Has P275/65R18 street tires on OEM rims.

My driveway is 1,000 feet of dirt but my commute to work is 35 miles of highway. With the amount of rain we've had this past year I've had to park our car and 2-wheel drive truck a couple times. I also travel from South MS to NW LA at least once a month (about 700 miles round-trip). The land up there is also slick and sticky when it's wet. The local dump is a mess even when it's dry.

Would like to find something a little more aggressive than the Nitto Terra Grapplers I have on my Jeep but that gets as good wear as those do. I'm not sure the Terra Grapplers will be aggressive enough with the additional weight of the truck (they certainly don't help on the 2-wheel drive Ram 2500 long-bed, crew-cab with 5.9 Cummins - they pack up fast and just spin). Will also be going with the LT tires when I do buy - truck has the max-tow package.

I am also looking to buy new wheels when the time comes to replace the tires and go with 17 inchers.

Would like to hear some real-world experience on semi-aggressive tires you've had on your F-150 with real mileage numbers.

 

I recommend Cooper ST Maxx and Cooper STT Pro's all the time.

 

Going with a lighter weight tire will help keep your mpg's up. I've run so many different tires over the years and for what you are looking for I would recommend the Cooper AT3 and a Michelin Defender LTX. If you really need something more aggressive I would definitely not look any further than the Cooper ST Maxx. They are heavier but they do the job for the more extreme offroad conditions. Nearly all of the loggers around here run them. I'm currently running the Cooper AT3 again and love them.
