Read the short take below, then confirm specs, stock, price history, and install requirements before choosing a seller.
Our take
Our take: Cooper Discoverer AT3 XLT LT285/70R17 belongs on this shelf because it gives F-150 XLT 4x4 SuperCrew shoppers another real all-terrain choice instead of forcing every owner toward the same tire. Cooper positions the AT3 XLT around heavy loads, towing, off-road control, 3PMSF capability, and a long treadwear warranty, which makes it a practical alternative to more aggressive hybrid tires. The official product and warranty resources explain why customers shop it, while the retail size page keeps the recommendation grounded in the same measurable fitment checks as the other LT285/70R17 tires. a road-friendly all-terrain with stronger towing and hauling posture than softer SUV tires Confirm the selected tire is the LT XLT version, because the AT3 family has multiple variants that should not share one fitment answer. Use it for comparison and fitment planning, then verify load range, wheel width, offset, stock, and the final seller page before ordering.

Compatibility by model year
Year range is only the first pass. The final answer still depends on model, trim, body style, drive, suspension package, and current seller fitment data.
2021-current Ford F-150 14th-generation trucks when LT285/70R17 specs stay inside the route limits
This is a spec-based tire fitment, not a blanket model-year promise. The LT285/70R17 size has to stay inside the F-150 XLT 4x4 SuperCrew route's 34.5 inch tire-diameter limit and must be paired with the right load, rim width, and wheel offset.
Verified trim route

Trim/body rules
The checked route is a 2023 XLT 4x4 SuperCrew on stock-height guidance. Tremor, Raptor, lifted, towing-heavy, or brake-upgraded trucks need their own clearance and load checks before inheriting this answer.
Why this year range
Ford redesigned the F-150 for 2021, so this guidance stays with the 14th-generation clearance record instead of mixing current fitment with older 2015-2020 owner reports.
