2023 Ford Explorer Tire Size & Pressure Guide

As an ASE-certified master technician, I regularly service the 2023 Ford Explorer. Whether you're driving the family-hauling XLT, the luxurious Platinum, or the high-performance ST, having the correct tire and wheel specifications is crucial for safety, ride comfort, and handling. Below is a comprehensive guide to the tire sizes, pressures, and wheel specs for your 2023 Ford Explorer.

Quick Answer

Here are the most critical tire and wheel specifications for the 2023 Ford Explorer:

• OEM Tire Size: 255/65R18 (Base, XLT), 255/55R20 (Limited, ST-Line, Timberline), or 275/45R21 (ST, Platinum)
• Recommended Cold Tire Pressure: 33 to 35 PSI Front & Rear (Check your driver's side door placard for your exact trim)
• Bolt Pattern: 5x114.3 mm (5x4.5")
• Wheel Size: 18x8J, 20x8.5J, or 21x9J (depending on trim)
• Wheel Offset: +35mm to +44mm
• Load Index & Speed Rating: 111H (18"), 107V (20"), 110V (21")
• Spare Tire Size: T165/70R18 (Compact Spare)
• TPMS Frequency: 315 MHz (Direct TPMS)

Tire Sizes by Trim

The 2023 Ford Explorer offers several wheel and tire packages depending on the trim level. Here is a breakdown of the standard sizes:

Note: Some XLTs may have optional 20-inch wheels, and some Platinums may come with 20-inch wheels. Always verify your current tire sidewall.

Recommended Replacement Tires

When it's time to replace the rubber on your Explorer, choosing the right tire depends on your driving habits, climate, and budget. Here are my top recommendations as a master tech:

1. Michelin Defender LTX M/S (Premium / Top Tier): The gold standard for SUVs. Incredible tread life, excellent wet traction, and a quiet, comfortable highway ride. Highly recommended for XLT and Limited trims.
2. Pirelli Scorpion Verde All Season Plus II (Mid-High Tier): An excellent choice for eco-conscious drivers looking for low rolling resistance to improve fuel economy, without sacrificing all-season grip.
3. Falken Wildpeak A/T Trail (Off-Road / Adventure): If you drive a Timberline or frequently take your Explorer down unpaved roads, this mild all-terrain tire offers rugged looks and trail capability while maintaining good road manners.
4. General AltiMAX RT43 (Budget-Friendly): A solid touring tire that provides great value. It performs admirably in wet and dry conditions and offers good longevity for the price.

When to Inflate to Max Load PSI

While the Ford Explorer is a mid-size SUV and not an HD (Heavy Duty) truck, it can be equipped with a Class IV Trailer Tow Package, allowing it to tow up to 5,600 lbs.

If you are maxing out the vehicle’s payload with passengers and cargo, or towing a heavy trailer, you should increase the rear tire pressure closer to the maximum cold PSI listed on the tire's sidewall (typically around 44-51 PSI, depending on the tire). This prevents the tire from flexing excessively under heavy loads, which causes dangerous heat buildup and sloppy handling. Once you are done towing or hauling, return the pressure to the standard 33-35 PSI listed on the door placard for normal driving.

Lug Nut Torque & Pattern

Proper wheel installation is vital to prevent warped brake rotors and ensure wheel security.

• Bolt Pattern: 5x114.3 mm (5x4.5 inches)
• Lug Nut Torque: 150 lb-ft (204 Nm)
• Lug Nut Thread Size: M14 x 1.5

Tech Tip: 150 lb-ft is significantly higher than many older passenger cars. Always use a calibrated torque wrench. Do not rely on an impact gun alone, as over-tightening or uneven tightening can quickly ruin your brake rotors.

Common Tire Issues for this Vehicle

In the service bay, I commonly see a few specific tire-related issues with the newer generation Ford Explorers:

• Inner Edge Wear on the Rear Tires: The Explorer's independent rear suspension can fall out of alignment, specifically regarding negative camber and toe. If the vehicle is frequently loaded heavy, the inner edges of the rear tires will wear down prematurely. Get a four-wheel alignment once a year.
• ST Trim 21-Inch Tire Bubbles: The low-profile 275/45R21 tires on the ST and Platinum trims look fantastic, but the short sidewall offers less impact protection. Potholes can easily cause sidewall bubbles or bent rims.
• TPMS Sensor Battery Life: While a 2023 model won't have this issue yet, Ford's 315 MHz TPMS sensors typically last about 7 to 10 years. If you are reading this years down the line, replacing the sensors when you buy a new set of tires is a smart preventative measure.
