Ford Trucks F-150 STX Tires

Ford Trucks F-150 STX uses seven listed tire sizes across the 2006-2014 run: 255/65R17 for 2006-2013, 255/70R17 for 2006-2009, 265/60R18 for 2008-2014, 275/65R18 for 2008-2014, 265/70R17 for 2010-2014, 235/75R17 for 2014, and 275/55R20 for 2014. The rim diameters tied to those sizes are 17, 18, and 20 inches, and the rim diameter is built directly into each metric size code.

That range means there is no single all-years tire size for Ford Trucks F-150 STX. Start with the model year, then verify the wheel diameter on the truck itself, and finally match the full size shown on the tire placard or the current tires if they are known to be correct.

Ford Trucks F-150 STX uses 17-inch, 18-inch, and 20-inch rim diameters across the years covered here. The earliest years begin with 17-inch fitments, 18-inch sizes appear starting in 2008, and 20-inch fitment appears in 2014. Metric radial sizing makes this easier to read than older tire formats because the final number in sizes like 255/65R17 or 275/55R20 is the wheel diameter.

Wheel diameter is the first hard check to make before comparing brands or tread styles. A 17-inch tire will not fit an 18-inch wheel, and an 18-inch tire will not fit a 20-inch wheel, so confirming that number on the actual truck prevents the most common fitment mistake.

A 2014 Ford Trucks F-150 STX can show five listed tire sizes because that model year spans multiple wheel-package configurations. The sizes for 2014 include 235/75R17 and 265/70R17 on 17-inch wheels, 265/60R18 and 275/65R18 on 18-inch wheels, and 275/55R20 on 20-inch wheels. That is a wheel-diameter split rather than one tire fitting every 2014 STX.

The practical takeaway is that year alone is not enough for a 2014 Ford Trucks F-150 STX. Check the wheel size, compare the full size code on the truck, and make sure the replacement preserves the same diameter class before moving on to load rating or tread preference.

On a Ford Trucks F-150 STX, 255/65R17 is a modern metric radial size. The 255 is the tire's section width in millimeters, 65 is the aspect ratio showing the sidewall height as 65 percent of the width, R means radial construction, and 17 is the required rim diameter in inches. That makes it a 17-inch wheel fitment, not an 18-inch or 20-inch option.

Reading the size this way helps you compare similar STX choices that may share a wheel diameter but differ in width or sidewall height. If your truck currently uses another 17-inch size such as 255/70R17 or 265/70R17, do not assume 255/65R17 is interchangeable without verifying the original specification for that specific truck.

A 2010 Ford Trucks F-150 STX can use more than one listed size, including 255/65R17, 265/70R17, 265/60R18, and 275/65R18. The correct choice depends first on wheel diameter, then on the exact size the truck was equipped to use. For 2010, that means distinguishing between 17-inch and 18-inch wheel packages before comparing any available product.

Use the driver's door placard, the existing tire size if the setup is known to be correct, and the wheel diameter stamped or measured on the truck. Once those agree, you can narrow the choice to the proper size and then compare details such as load rating and approved rim-width range.

The available products listed for Ford Trucks F-150 STX come from BFGoodrich. The current product coverage shown here includes BFGoodrich All-Terrain T/A KO2 options in 255/65R17, 265/70R17, and 275/65R18. Those are all radial tires and all use RWL sidewall styling in the listed entries.

That means brand choice is narrow within the currently available products, so fitment accuracy becomes more important than broad brand comparison. Match the exact size first, then review the specific load version of the tire where more than one option exists in the same size, as with 265/70R17.

The available Ford Trucks F-150 STX products shown here use RWL sidewall styling, which stands for raised white letters. That sidewall treatment appears on the listed BFGoodrich All-Terrain T/A KO2 tires in the covered sizes. No alternate sidewall style appears in the available products provided here.

For an STX truck, RWL can suit the pickup's sport-truck and off-road look, but the main fitment issue is still the exact size and wheel diameter. If your truck currently uses a different appearance or wheel package, keep the original size and wheel class as the first priority before focusing on sidewall presentation.

A Ford Trucks F-150 STX should be stored on a clean, dry surface away from direct sunlight, electric motors, welders, furnaces, or ozone-producing equipment that can age rubber. Keep the tires inflated to an appropriate maintenance pressure for storage, and avoid letting the truck sit for long periods with visibly low tires. If the truck will be parked for months, moving it occasionally helps reduce flat spotting.

Because STX models can carry truck-sized loads and heavier wheel packages, neglect during storage can show up as vibration, sidewall stress, or uneven wear once the truck returns to use. A covered indoor space and periodic pressure checks go a long way toward preserving both tire shape and ride quality.

Tires on a Ford Trucks F-150 STX should be visually inspected at least monthly and again before any longer drive, towing trip, or seasonal return to service. Look for pressure loss, cracking, punctures, irregular shoulder wear, and any sign of impact damage from curbs or rough surfaces. On sizes that have multiple load-rated versions, confirm that all four tires match the intended use of the truck.

Regular inspection matters because a full-size pickup can hide developing tire problems until they affect braking, tracking, or load carrying. Catching wear or damage early also helps confirm whether the truck is on the correct size and whether alignment or suspension issues are shortening tire life.

Tires on a Ford Trucks F-150 STX should be replaced when they show age cracking, sidewall damage, impact breaks, repeated air loss, severe uneven wear, or any condition a qualified tire professional considers unsafe, even if tread depth still looks usable. Collector-minded owners sometimes focus on tread alone, but age and structural condition matter just as much as remaining pattern depth.

That is especially important on trucks that see intermittent use, because low annual mileage can mask rubber aging. If the truck has sat for long periods, inspect the date codes and overall condition before returning it to regular road use, particularly if it will carry passengers, cargo, or highway speeds.

Ford Trucks F-150 STX used multiple original size paths across 2006-2014 rather than one single tire specification. The listed year ranges show 17-inch sizes at the start, 18-inch sizes appearing from 2008 onward, and a 20-inch fitment appearing in 2014. That means original fitment depends on the exact year and wheel package on the truck.

For a factory-correct restoration or preservation effort, the best approach is to match the truck's original wheel diameter and compare the present size to the vehicle placard and period Ford literature for that exact truck. STX appearance and wheel-package differences make those original references more useful than relying on year alone.

Correct tire fitment can affect both presentation and perceived authenticity on a Ford Trucks F-150 STX, especially when the truck is being preserved in near-factory form. A truck wearing the wrong wheel diameter or an incorrect overall tire profile can look noticeably different from how that configuration originally sat. On newer collectible trucks, stance and wheel-package correctness matter as much as brand recognition.

If the goal is show judging or a faithful restoration, keep the exact size family aligned with the truck's original wheel package. Owners pursuing originality should also compare sidewall appearance and load version to period expectations, and consult marque communities when the truck falls into a year with several listed size options.

The available Ford Trucks F-150 STX products shown here use RWL, or raised white letters. That style fits the sport-truck and all-terrain character often associated with STX-era pickups, especially when paired with all-terrain tread. No other sidewall style appears in the currently listed products for the covered sizes.

For a restoration-minded owner, the right sidewall style should follow the truck's original appearance theme and wheel package. If your STX was delivered with a more street-oriented or more off-road look, compare surviving photos, factory brochures, and the truck's current wheel setup before choosing sidewall presentation.

The listed Ford Trucks F-150 STX products are modern radial truck tires, so they are intended for real road use when they are the correct size for the truck, properly mounted on the correct wheel diameter, and used within their load and pressure limits. Safety depends on matching the tire to the wheel and vehicle configuration, not simply on whether the size appears somewhere within the STX year range.

Before regular road use, verify the exact size, check inflation pressure, inspect for damage, and confirm that all four tires are appropriate for the truck's intended work. A full-size pickup can place meaningful demands on its tires, especially when carrying cargo or traveling at highway speed.

Before driving a Ford Trucks F-150 STX, check tire pressure, visible condition, tread wear pattern, and the exact size on all four corners. Also confirm that the tires match the wheel diameter on the truck and that any replacement size still aligns with the intended STX configuration. On available 265/70R17 products, note that there are different load-rated versions within the same size.

Those checks help prevent common problems such as running mismatched tire diameters, overloading a lighter-rated tire, or discovering too late that the truck is on the wrong wheel package. A quick walkaround before each trip is especially worthwhile if the truck alternates between light use and heavier duty.

A Ford Trucks F-150 STX should only be driven at speeds appropriate to the exact tire size, service description, load, and condition of the tires actually fitted to the truck. The listed products include service markings such as 114S, 112S, 121S, and 123/120R, and those markings matter along with inflation and payload. Safe speed is never determined by size alone.

For practical use, keep the truck within normal road speeds only when the tires are in sound condition, correctly inflated, and matched to the truck's load demands. If the truck is carrying cargo, towing, or using an LT-type load-rated setup, be more conservative and make sure the whole tire-and-wheel package suits that duty.
