2006 Ford Trucks F-350 Super Duty King Ranch Tires

The 2006 Ford Trucks F-350 Super Duty King Ranch uses more than one tire size. Depending on configuration, the fitments are 275/65R18, 245/75R17, 275/65R20, and 275/70R18, and all of them are radial sizes. The split comes from differences between 4x2 and 4x4 trucks, along with single-rear-wheel and dual-rear-wheel setups.

Choosing the right one starts with identifying the exact sub-model and then confirming the wheel diameter actually on the truck. A DRW truck does not use the same fitment as a single-rear-wheel version, and a 4x4 may carry either an 18-inch or 20-inch wheel. Checking the door-jamb label, current tire size, and wheel stamping helps avoid ordering the right tire in the wrong size.

Rim diameter varies on the 2006 Ford Trucks F-350 Super Duty King Ranch. The covered fitments use 17-inch, 18-inch, and 20-inch wheels, depending on the exact truck configuration and tire size. That means wheel diameter is a core part of fitment, not just a secondary detail.

The practical point is simple: tire size and wheel diameter must match exactly. A 245/75R17 belongs on a 17-inch wheel, while 275/65R18 and 275/70R18 require 18-inch wheels, and 275/65R20 requires a 20-inch wheel. On a used heavy-duty pickup, aftermarket wheels are common, so it is smart to verify the actual wheel before comparing tires, especially on 4x4 and DRW trucks.

The 2006 Ford Trucks F-350 Super Duty King Ranch has multiple tire sizes because the model was offered in different working configurations. Single-rear-wheel and dual-rear-wheel trucks do not share the same fitment, and the 4x4 version can also appear with different wheel diameters. Those differences affect both the size code and the rim size required.

That matters because the truck’s badge alone is not enough to select tires correctly. A buyer needs to confirm whether the truck is 4x2 or 4x4, whether it is DRW, and whether it has 17-, 18-, or 20-inch wheels. Once those details are confirmed, the tire search becomes much more straightforward and the available product comparisons make better sense.

Start with the exact size and configuration, because this King Ranch can use four different radial tire sizes. After that, compare the tire’s rim-width range, load capacity at its stated pressure, overall tire weight, and sidewall presentation. Those details matter more on a heavy-duty truck than simply choosing by brand name alone.

The next step is matching the tire to how the truck is actually used. A DRW truck, a 4x4 on 20-inch wheels, and a single-rear-wheel 4x2 do not ask the same things from a tire. It also helps to confirm whether the truck still has its original wheel setup or has been changed for towing, off-road use, or appearance.

Sidewall style varies by size on this application. The available BFGoodrich All-Terrain T/A KO2 options include raised white letter sidewalls in 275/65R18, 245/75R17, and 275/70R18, while the 275/65R20 version uses a black sidewall presentation. The sidewall choice is tied to the size, not offered across every fitment equally.

That means appearance decisions come after the fitment is confirmed. If the truck requires 245/75R17 for a DRW setup, for example, the available sidewall look is part of that size’s package rather than a universal styling option. Sidewall treatment can influence the truck’s visual character, but correct size, wheel match, and load-oriented suitability still come first.

The available products for the 2006 Ford Trucks F-350 Super Duty King Ranch are centered on the BFGoodrich All-Terrain T/A KO2 series. That series appears across the covered 17-inch, 18-inch, and 20-inch fitments, giving the truck a consistent all-terrain product family even though the sizes vary by configuration.

Because the series remains the same, the real comparison shifts to the exact size, sidewall style, rim-width specification, and load figure attached to that size. This can simplify shopping once the sub-model is confirmed, but it does not remove the need to verify whether the truck is DRW, whether it is 4x4, and which wheel diameter it actually uses.

Yes. Modifications can change tire fitment on a 2006 Ford Trucks F-350 Super Duty King Ranch even when the truck started with one of the correct factory-style size groups. Aftermarket wheels, changes in wheel width, suspension lifts or lowering, and body or steering alterations can all affect which tire size clears properly.

That is especially important here because the truck already spans 17-, 18-, and 20-inch wheel fitments across different versions. A buyer should check the actual wheel diameter, width, and tire size now on the truck, then inspect turning clearance and rear spacing where applicable. On DRW models, confirming the exact rear-wheel setup is just as important as the size itself.

Before road use, inspect the wheels for damage, confirm lug hardware condition, and make sure the new tires match the truck’s correct size and wheel diameter. Tire pressure should be set properly, and the truck’s suspension, steering, and alignment condition deserve attention too, especially on a heavy-duty pickup that may tow or carry substantial loads.

A quick visual check should also include sidewall clearance, tread-to-fender clearance, and even wear patterns after the first miles of driving. On a truck that has been stored or used intermittently, it helps to look over brake components and wheel bearings at the same time. Any vibration, pulling, or rubbing after installation should be addressed before regular use.

Regular pressure checks are the foundation, especially on a truck that may see towing, hauling, or long periods of sitting between uses. Tires should also be inspected for uneven wear, cuts, punctures, weather cracking, and signs of slow air loss. Keeping the correct size on the correct wheel matters just as much as routine maintenance.

Rotation, alignment checks, and prompt correction of suspension wear help preserve tire life on an F-350. Storage habits matter too, particularly if the truck is not driven often; long exposure to heat, direct sun, and moisture can age tires even when tread remains. On DRW models, extra attention to rear tire condition and spacing helps prevent avoidable road-use problems.
