Ford Trucks F-350 Super Duty King Ranch Tires

Ford Trucks F-350 Super Duty King Ranch uses four tire sizes across the 2005 to 2017 range: 245/75R17, 275/65R18, 275/70R18, and 275/65R20. The 245/75R17 size uses a 17-inch rim, both 275/65R18 and 275/70R18 use 18-inch rims, and 275/65R20 uses a 20-inch rim. The 20-inch size appears from 2006 through 2017, while the 17-inch and 18-inch sizes run through the full span shown here.

That means year alone does not identify the correct tire on a Ford Trucks F-350 Super Duty King Ranch. The practical approach is to read the size already mounted on the truck, confirm the wheel diameter, and then compare that to the door-jamb tire information label or original wheel package for the specific truck.

A 2006 Ford Trucks F-350 Super Duty King Ranch can show 245/75R17, 275/65R18, 275/70R18, and 275/65R20 because the split is driven by wheel diameter and configuration within the same model year. In that year, the range spans 17-inch, 18-inch, and 20-inch wheels rather than a single universal fitment. Two of the listed sizes also share the same 18-inch wheel diameter but differ in aspect ratio.

The useful takeaway is that a 2006 Ford Trucks F-350 Super Duty King Ranch must be matched by its actual wheel and tire package, not just by model name. If the truck has changed hands or has aftermarket wheels, inspect the current tire size and wheel diameter carefully before selecting a replacement.

Ford Trucks F-350 Super Duty King Ranch uses 17-inch, 18-inch, and 20-inch rim diameters in the range covered here. The earliest year shown, 2005, already includes both 17-inch and 18-inch fitments, and 20-inch fitments join the lineup in 2006. That creates a three-way wheel-diameter spread across much of the production run.

Wheel diameter is the first fitment point to verify because none of these sizes interchange across different rim diameters. A truck wearing 17-inch wheels cannot take an 18-inch or 20-inch tire, and a 20-inch wheel package from a later truck needs a true 20-inch fitment rather than a close-looking 18-inch alternative.

A 2012 Ford Trucks F-350 Super Duty King Ranch can use 245/75R17, 275/65R18, 275/70R18, or 275/65R20, so the correct size depends on the wheel package installed on that truck. Each size corresponds to a specific rim diameter, and two of the options share 18-inch wheels while differing in profile. The proper match is the combination of the wheel diameter and the exact size spec for that individual truck.

Start by reading the full size marking on the sidewall, then confirm that the wheel diameter matches the tire’s final number. If the truck has had wheel or suspension changes over time, compare the current setup to the vehicle placard and the intended use so you stay within a fitment that suits the truck’s load-carrying role.

Ford Trucks F-350 Super Duty King Ranch tires in the sizes listed here are available with RWL and RBL sidewall styles. The 245/75R17, 275/65R18, and 275/70R18 entries use raised white letters, while the 275/65R20 entry uses raised black letters. All of the listed products are radial all-terrain tires from the same series family.

Sidewall style affects appearance more than fitment, but it can make a noticeable difference on a King Ranch truck where visual presentation matters. If you are trying to maintain a consistent look, check all four tires on the truck and match the visible sidewall treatment rather than choosing solely by size.

The products listed for Ford Trucks F-350 Super Duty King Ranch in these sizes come from one brand: BFGoodrich. Each available fitment is part of the BFGoodrich All-Terrain T/A KO2 line, with separate sizing for the 17-inch, 18-inch, and 20-inch wheel applications. That means the brand choice here is narrow, while the fitment choice is driven by size and wheel diameter.

Because the same brand spans all four sizes, the key decision is less about manufacturer and more about selecting the exact size the truck requires. Match the wheel diameter first, then the full size code, and finally consider whether the sidewall style and load specification suit how the truck is used.

A Ford Trucks F-350 Super Duty King Ranch should be stored on a clean, dry surface away from prolonged sunlight, ozone sources, and large temperature swings. Keep the tires inflated to an appropriate storage pressure for the truck’s setup and avoid letting a heavily loaded truck sit for long periods without movement. Heavy-duty tires can develop flat spotting or age unevenly when they carry the same weight in the same position for months at a time.

If the truck is used seasonally, move it periodically or support it in a way that reduces long-term stress on the tires and suspension. Before returning the truck to regular use, inspect the sidewalls, tread blocks, and valve stems so storage-related aging does not go unnoticed.

Tires on a Ford Trucks F-350 Super Duty King Ranch should be inspected regularly even when the truck sees low annual mileage. A heavy-duty pickup can place substantial strain on its tires through towing, hauling, and front-end loading, so pressure, tread wear, weather checking, and uneven shoulder wear deserve frequent attention. Any truck that sits for long periods should be checked again before it returns to road use.

A practical routine is to inspect the tires before longer trips, after load changes, and at seasonal intervals through the year. Pay special attention if the truck has dual-purpose work and recreational use, because changing loads can reveal alignment, inflation, or rotation issues faster than mileage alone would suggest.

Tires on a Ford Trucks F-350 Super Duty King Ranch should be replaced when age, sidewall cracking, impact damage, irregular wear, or internal deterioration becomes a concern, even if the tread still looks usable. Collector-owned and low-mileage trucks often age their tires out before they wear them out. Load-bearing heavy-duty tires deserve extra caution because hidden age-related weakness matters more on a truck expected to carry weight.

If a Ford Trucks F-350 Super Duty King Ranch has spent years parked, assume age is as important as tread depth and have the tires evaluated before serious road use. Replacement becomes especially important before towing, highway travel, or carrying substantial loads, where an older tire’s margin of safety narrows quickly.

The listed Ford Trucks F-350 Super Duty King Ranch tires are modern radial truck tires, so they are suitable for normal road use when they are the correct size for the wheel and are in sound condition. The available products include load-capable fitments with rim diameters of 17, 18, and 20 inches, each intended for a specific wheel package. Safety depends on matching the size correctly and maintaining the tire according to the truck’s service demands.

Road use should always begin with a check of inflation pressure, condition, and whether the truck’s current wheel-and-tire combination matches its intended load. If the truck tows, hauls, or spends time at highway speed, tire condition and proper fitment become even more important than they would on a lighter-duty collector vehicle.

Before driving a Ford Trucks F-350 Super Duty King Ranch, check that all four tires match the wheel diameter they are mounted on, inspect for cuts or sidewall cracking, and verify inflation for the truck’s current load. On this model, that also means confirming whether the truck is on 17-inch, 18-inch, or 20-inch wheels, because several sizes overlap across the same production years. Tread condition and visible wear pattern should also be reviewed before road use.

That pre-drive inspection matters especially on a truck that has sat unused or alternates between unloaded driving and heavy towing duty. Uneven wear, age cracking, or a mismatched tire can turn into a far bigger issue once the truck is carrying weight or traveling at sustained road speed.

A Ford Trucks F-350 Super Duty King Ranch should be driven at speeds appropriate to the tire size, tire condition, load carried, and the truck’s overall mechanical state rather than by appearance alone. These are heavy-duty trucks, and tire stress rises quickly with added cargo, trailer tongue weight, heat, and sustained highway use. Even a correctly sized modern radial should be treated as part of the truck’s total load and braking system.

The sensible approach is to keep speed moderate whenever the truck is heavily loaded or when tire age and service history are uncertain. If the truck is freshly returned to service after storage, begin with shorter drives and careful monitoring before expecting it to handle long-distance or full-load work confidently.
