Owners of the 2011 Ford Explorer XLT often appreciate the blend of capability and comfort this model offers, but understanding the specific tire size is crucial for maintaining performance and safety. The correct tire dimensions ensure proper handling, fuel efficiency, and speedometer accuracy, making this specification a fundamental detail for any maintenance routine. This guide breaks down the exact tire size for the 2011 XLT, along with the reasoning behind OEM specifications and practical advice for replacements.
Factory Specifications for the 2011 Model Year
The 2011 Ford Explorer XLT was typically equipped with P235/70R16 tires as the standard configuration for most trims and driving conditions. This size indicates a tire with a section width of 235 millimeters, an aspect ratio of 70 (meaning the sidewall height is 70% of the width), and a 16-inch wheel diameter. While this was the default fitment for the base XLT, it is always wise to verify the details located on the tire information placard, which is usually found on the driver’s side door jamb.
Decoding the Tire Size Code
Understanding the alphanumeric sequence on the sidewall helps clarify why P235/70R16 is the ideal measurement for the XLT. The "P" designates the tire as a P-metric, suitable for passenger vehicles. The "235" represents the tread width in millimeters when measured from sidewall to sidewall. The "70" is the aspect ratio, which describes the height of the tire's sidewall as a percentage of its width. Finally, the "R" stands for radial construction, and the "16" confirms that the tire fits a 16-inch diameter wheel.
Importance of Proper Sizing
Sticking with the recommended P235/70R16 size is essential for the 2011 Explorer XLT's drivetrain and electronic stability systems. Deviating significantly from the OEM diameter can trigger issues with the anti-lock braking system (ABS) and traction control, as the vehicle's sensors calculate speed based on the original circumference. Furthermore, the correct size ensures the fender wells provide adequate clearance during turns and over rough terrain, preventing unsightly rubbing or potential damage to the body panels.
Load Range and Speed Rating
Beyond the width and diameter, the load index and speed rating are critical safety markers that should match the original equipment. For the standard 2011 XLT, a tire with a load index of 100 (capable of supporting 1,804 pounds) and a speed rating of S (112 mph) is generally acceptable. These numbers ensure the tire can handle the weight of the vehicle and passengers while providing a comfortable buffer for normal highway driving without excessive heat buildup.
Aftermarket Options and Upgrades
When it is time for replacement, owners have the flexibility to choose between OEM-quality replacements or performance-oriented alternatives. All-season tires are a popular choice for the Explorer XLT, offering a balanced mix of longevity, comfort, and wet-weather traction. For those who frequently tow or traverse challenging weather, considering all-terrain tires with a slightly larger diameter can provide enhanced grip, provided the overall height remains within 3% of the factory specification to protect the vehicle's systems.
Wheel Compatibility
The 16-inch wheel diameter associated with the P235/70R16 size offers a wide range of aftermarket wheel options. Owners looking to customize the appearance of their Explorer XLT can choose from various steel or alloy wheels in this size without affecting the vehicle's geometry. However, it is vital to ensure the new wheel's bolt pattern, center bore, and offset are compatible with the Explorer XLT's suspension components to guarantee a safe and secure fit.
