Tire sizes by trim

Recommended replacement tires

The 2019 Ford Ranger, a versatile mid-size pickup, benefits greatly from tires that can handle both daily driving and light-duty off-roading. Here are some popular options across different price tiers:

• BFGoodrich All-Terrain T/A KO2 (Premium): These are a perennial favorite for truck owners seeking excellent all-terrain performance, durability, and a rugged look. Expect to pay around $250-$300+ per tire, depending on size.
• Falken Wildpeak A/T3W (Mid-Range): A fantastic all-around tire that offers a great balance of off-road capability, on-road comfort, and wet-weather traction. These typically range from $180-$250 per tire.
• Hankook Dynapro AT2 (Value): A solid choice for those who need good all-terrain performance without breaking the bank. They offer comfortable highway manners and decent off-road grip. Prices generally fall in the $150-$200 range per tire.
• Michelin Defender LTX M/S (Premium, Highway-focused): If your Ranger spends most of its time on paved roads and you prioritize ride comfort, longevity, and quietness, the Defender LTX M/S is an excellent option. They still offer good light-duty off-road capability. Expect prices similar to the KO2s.

When to inflate to max load psi

For the 2019 Ford Ranger, it is not recommended to inflate your tires to the maximum PSI indicated on the tire sidewall for everyday driving. The maximum pressure on the tire sidewall is the maximum safe pressure for the tire itself, not the recommended operating pressure for your vehicle. For optimal ride, handling, tire wear, and safety, always refer to the tire placard located on the driver's side door jamb for the recommended cold tire inflation pressure (which is 35 PSI for the 2019 Ranger).

Only consider increasing tire pressure above the door placard recommendation if you are consistently carrying or towing extremely heavy loads that approach the vehicle's maximum gross vehicle weight rating (GVWR) or gross combined weight rating (GCWR). Even then, only increase pressure incrementally and never exceed the maximum cold inflation pressure stamped on the tire sidewall. Incorrectly high tire pressure can lead to a harsh ride, premature tire wear in the center, and reduced traction.

Lug nut torque & pattern

The 2019 Ford Ranger utilizes a 6x139.7mm bolt pattern. This means there are 6 lug nuts, and the circle formed by the centers of these lug nuts has a diameter of 139.7 millimeters. When remounting wheels, it is crucial to tighten the lug nuts to the manufacturer's specified torque to ensure proper wheel retention and prevent issues like vibration or wheel stud damage.

• Lug Nut Torque: 100 ft-lbs (135 Nm)

Always use a torque wrench to achieve the correct specification. Tighten the lug nuts in a star or crisscross pattern to ensure the wheel is seated evenly against the hub. After approximately 50-100 miles of driving after a wheel has been removed or installed, it is good practice to re-check the lug nut torque to confirm they are still properly tightened.

Common tire issues for this vehicle

The 2019 Ford Ranger is a reliable truck, but like any vehicle, certain tire-related issues can arise. Understanding these can help you maintain your tires and prolong their life:

• Uneven Tire Wear: This is a common issue that can stem from several factors, including improper tire inflation (under or over-inflation), misaligned suspension, or unbalanced wheels. Regular tire rotations (every 5,000-7,500 miles) and alignments can mitigate this.
• TPMS Malfunctions: The Tire Pressure Monitoring System (TPMS) alerts you to low tire pressure. If the TPMS light comes on and your tires are properly inflated, it could indicate a faulty sensor or that the system needs to be reset after a tire rotation or replacement. The 315 MHz sensors are generally reliable, but can fail over time due to battery depletion or damage.
• Vibrations at Highway Speeds: This often points to unbalanced wheels or tires. Hitting potholes can sometimes knock wheel weights off or slightly deform a tire. Having your tires balanced with a quality wheel balancer can usually resolve this.
• "Cupping" or "Scalloping" Wear: This distinctive wear pattern (alternating high and low spots around the circumference of the tire) is often a sign of worn shock absorbers or other suspension components. If you notice this, it's worth having your suspension inspected.
