2020 Ford Ranger Tire Size, Pressure, & Wheel Specs

As an ASE-certified master technician, I see plenty of mid-size trucks roll through the bays. The 2020 Ford Ranger is a capable, versatile pickup, whether you are hauling gear to a job site or taking the family off the grid for the weekend. Choosing the right tires and keeping them at the correct pressure is critical for ride comfort, fuel economy, and safety.

Below is your comprehensive guide to the tire and wheel specifications for the 2020 Ford Ranger.

Quick answer: 2020 Ford Ranger Tire & Wheel Specs

Here are the essential tire and wheel specifications you need to know for your 2020 Ford Ranger:

• OEM Tire Sizes: 255/70R16, 255/65R17, 265/65R17, or 265/60R18 (depending on trim and packages).
• Recommended Cold Tire Pressure: Typically 30 to 35 PSI front and rear (always check the driver's side door jamb placard for your specific build).
• Bolt Pattern: 6x139.7 mm (6x5.5 inches).
• Wheel Sizes: 16x7", 17x8", or 18x8" with a typical offset of +55mm.
• Load Index/Speed Rating: Usually 110T to 112T depending on the exact OEM tire.
• Spare Tire Size: Full-size spare on a steel wheel (matches the diameter of the factory tires).
• TPMS Frequency: 315 MHz (standard for North American models).

Tire sizes by trim

Ford offered the 2020 Ranger in a few different trims with various suspension packages (like the FX4 Off-Road package). Here is how the tire sizes break down:

Recommended replacement tires

When it is time to replace the rubber on your Ranger, you have a lot of great options depending on your driving habits. Here are a few technician-recommended choices:

1. Falken Wildpeak A/T3W (Premium All-Terrain) – Excellent for Rangers equipped with the FX4 package. These tires offer aggressive off-road traction while maintaining impressive on-road manners and severe snow ratings.
2. Michelin Defender LTX M/S (Premium Highway/All-Season) – If your Ranger spends 99% of its life on the pavement, this is the gold standard. They last an incredibly long time, ride smooth, and offer fantastic wet traction.
3. Cooper Discoverer AT3 4S (Mid-Tier All-Terrain) – A great balance of price and performance. It looks rugged but doesn't howl on the highway.
4. Kumho Crugen HT51 (Budget Highway/All-Season) – A solid, affordable choice for daily driving and light hauling that won't break the bank.

When to inflate to max load psi

While the 2020 Ford Ranger is a mid-size truck and not a Heavy Duty (HD) workhorse, you still need to monitor tire pressure when maximizing its 1,860-lb payload or 7,500-lb towing capacity.

For daily driving empty, stick to the 30-35 PSI listed on the door placard to ensure even tire wear and ride comfort. However, if you are loading up the bed with gravel or towing a heavy camper, you can safely increase the rear tire pressure closer to the "Max Cold Press" listed on the tire's sidewall (often 40-44 PSI for standard load tires, or higher if you've upgraded to LT/E-load tires). Doing this reduces sidewall flex, keeps the tire cooler, and improves trailer stability. Just remember to air back down to the placard pressure once you unload.

Lug nut torque & pattern

Proper wheel installation is a critical safety step that is too often ignored. For the 2020 Ford Ranger:

• Lug Nut Torque: 100 lb-ft (135 Nm).
• Bolt Pattern: 6-lug (6x139.7).

Always use a calibrated torque wrench, and tighten the lug nuts in a crisscross (star) pattern to ensure the wheel sits perfectly flush against the hub. Re-check the torque after 50 to 100 miles of driving after installing new wheels or tires.

Common tire issues for this vehicle

The 2020 Ranger is generally easy on tires, but there are a few things to watch out for:

• Alignment drift from off-roading: Because Rangers are popular for trail riding, hitting ruts and rocks can knock the front end out of alignment. If you notice the steering wheel is off-center or the inner/outer edges of your front tires are wearing quickly, get an alignment check.
• Tire Cupping: If you rarely rotate your tires, the rear-wheel-drive bias of the Ranger can cause cupping or heel-toe wear on the front tires. Rotate your tires every 5,000 to 7,000 miles to keep the tread wearing evenly.
• TPMS Sensor Battery Life: The OEM sensors run on 315 MHz and typically last 5 to 7 years. Because this is a 2020 model, you may start seeing TPMS fault lights in the next year or two as the internal sensor batteries begin to die.
