Understanding Your 2018 Ford Explorer Tire Size
The correct 2018 Ford Explorer tire size is paramount for ensuring your vehicle operates safely and efficiently, directly impacting handling, braking, and even fuel economy. Factory-recommended sizes are meticulously chosen by engineers to complement the vehicle's suspension, braking system, and powertrain. Deviating significantly without understanding the implications can compromise these critical functions.
- OEM 2018 Ford Explorer tires are typically 245/65R17 or 255/50R20.
- Always check your driver's side doorjamb sticker for precise specifications.
- Tire size affects speedometer accuracy and ABS performance.
- Incorrect size can void warranty and compromise safety.
For the 2018 model year, Ford typically equipped the Explorer with two primary tire sizes depending on the trim level and optional packages. The most common factory specifications you'll encounter are 245/65R17 and 255/50R20. The number '17' and '20' refer to the wheel diameter in inches, while '245' and '255' indicate the tire's width in millimeters. The '65' and '50' are the aspect ratios, representing the tire's sidewall height as a percentage of its width. The 'R' signifies radial construction, standard on virtually all modern vehicles.
Locating Your Specific Tire Size
While general sizes are common, it is imperative to acknowledge that the definitive source for your vehicle's exact tire size is the sticker located on the driver's side doorjamb. This sticker provides a wealth of information, including the original equipment (OE) tire size, recommended tire pressure, and load index. Always cross-reference this information before purchasing new tires, as aftermarket wheels or specific packages might alter the original fitment. Understanding this principle is fundamental to avoiding costly mistakes.
This mechanism is critical for maintaining vehicle integrity and safety.
Impact of Tire Size on Performance and Safety
What happens when you stray from the recommended 2018 Ford Explorer tire size? The consequences can range from minor annoyances to significant safety hazards. A tire that is too large or too small can affect your speedometer and odometer readings, making them inaccurate. This means you could be driving faster or slower than indicated, and your mileage tracking will be off. Moreover, the anti-lock braking system (ABS) and electronic stability control (ESC) are calibrated based on the OE tire diameter. Mismatched tire sizes can lead to these systems not performing optimally, increasing stopping distances or affecting vehicle control during emergency maneuvers.
Consider the common mistake of installing tires with a significantly different overall diameter. This alters the vehicle's effective gear ratio and can lead to premature wear on the drivetrain components. The vehicle's computer expects a certain rotational speed for a given engine speed, and a larger tire spins slower, potentially confusing systems like traction control.
Confirm the overall tire diameter of any potential replacement size and compare it to your OE specification; aim for a variation of no more than 1-2% to minimize impacts on vehicle systems.
The primary consideration involves maintaining the vehicle's designed dynamic characteristics. If you're exploring tire size options, perhaps for off-road capability or a sportier look, you must also consider if the new tire size will fit without rubbing against the fenders or suspension components, especially when turning or under load. This often requires checking clearance for factors similar to what you'd consider when looking at a 5th gen 4runner tire size or even a case 580 rear tire size if you were dealing with larger equipment.
Maintaining the integrity of the tire-to-road contact patch and the vehicle's electronic systems is non-negotiable for safe operation.
Our analysis indicates that even slight deviations, when multiplied by thousands of rotations per mile, can cumulatively affect your vehicle's behavior and longevity. It is imperative to acknowledge that the tire is the sole point of contact between your vehicle and the road.
Choosing and Maintaining the Right Tires
When it comes to selecting new tires for your 2018 Ford Explorer, beyond just the correct size, you should also consider the tire's intended use, load rating, and speed rating. The OE tires are typically designed for a balance of comfort, all-season traction, and fuel efficiency. If your driving habits differ – perhaps more highway miles, off-road excursions, or towing – you might opt for specialized tires. A truck or performance tire might offer different benefits, much like choosing a talaria x3 tire size or a crf110 tire size would be specific to those different vehicles. For instance, a tire with a higher load index is essential if you frequently carry heavy loads or tow, ensuring the tire can safely support the weight. Similarly, the speed rating must be appropriate for the speeds you anticipate driving.
Common Tire Upgrades and Considerations
Many owners consider upgrading their tire and wheel size. A common move is going from the 17-inch wheels to 20-inch wheels, requiring a tire like the 255/50R20. This upgrade can enhance the vehicle's aesthetic appeal and potentially improve handling characteristics for on-road driving. However, larger wheels often mean lower-profile tires, which can result in a harsher ride and increased susceptibility to damage from potholes. The cost of larger tires also tends to be higher. When considering such changes, it's vital to ensure the new tire's overall diameter remains close to the original size to minimize impacts on vehicle systems, akin to how one would verify a cfmoto cforce 1000 x10 front tire size or a tw200 tire size for their respective machines.
Install all four tires of the same size, type, and tread pattern. Mixing different tires can severely compromise handling, especially in adverse conditions.
Regular maintenance is just as critical as selecting the correct size. This includes checking tire pressure at least monthly, rotating tires every 5,000-7,500 miles to ensure even wear, and performing wheel alignments as recommended or when you notice uneven tire wear or pulling. Properly inflated tires not only last longer but also contribute to better fuel economy and a smoother ride. If you notice any damage, such as bulges or cuts, it is crucial to have the tire inspected by a professional immediately. Such precision is paramount.
