When outfitting a 2017 Ford F-150 XLT, choosing the correct tire size is essential for safety, comfort, and capability. This guide breaks down OEM specifications, common replacement options, and key considerations specific to the XLT trim.
Below is a quick reference that summarizes typical tire sizes and related details for the 2017 Ford F-150 XLT based on wheel diameter and common use cases.
| Wheel Diameter | Typical Tire Width | Common Aspect Ratio | Recommended Use |
|---|---|---|---|
| 17 inches | 265 mm | 70 series | Everyday driving and light work |
| 18 inches | 285 mm | 65 series | Highway comfort and appearance |
| 19 inches | 285–305 mm | 60–65 series | Versatile on-road and light off-road |
| 20 inches | 285–315 mm | 55–60 series | Performance styling and heavier loads |
Understanding 2017 F-150 XLT OEM Specifications
Ford engineers the 2017 F-150 XLT to balance efficiency, towing capacity, and ride quality. The default tire size varies slightly based on whether the model comes with standard steel wheels or optional aluminum rims.
Most base configurations roll on 17-inch steel wheels shod in P235/70R16 or similar, which suits work-focused buyers. Buyers who select 18-inch aluminum wheels often receive P285/65R18 tires that emphasize comfort and highway noise reduction.
It is important to verify the exact size printed on the tire sidewall of your own vehicle before making any changes. Doing so helps you match load index and speed rating requirements while staying within manufacturer guidelines.
Performance and Handling Considerations
Tire diameter and aspect ratio directly affect acceleration, fuel economy, and speedometer accuracy on the 2017 F-150 XLT. Increasing wheel size typically lowers the aspect ratio, which can improve cornering response at the cost of a firmer ride.
For drivers who plan to tow trailers or carry heavy payloads, maintaining the correct OEM gross axle weight rating is essential. Larger tires with lower aspect ratios may reduce ground clearance slightly, which can matter on uneven job sites.
To minimize drivetrain stress, many experts recommend keeping total tire diameter within about 3 percent of the original specification. Staying within this range helps preserve stability, traction control, and anti-lock braking system performance.
Durability and Weather Suitability
The 2017 F-150 XLT often operates in demanding climates, so choosing tires with strong sidewalls and appropriate tread patterns is important. Look for all-season or light-truck tires that balance long wear with reasonable noise levels.
In regions with heavy snow or mud, owners sometimes switch to dedicated winter or mud-terrain tires. Be aware that aggressive tread designs can wear faster on pavement and may affect fuel efficiency and highway comfort.
Regular rotation and proper air pressure remain critical regardless of tire choice. For the XLT trim, maintaining recommended pressures helps protect the aluminum wheels and ensures consistent payload capacity across the truck bed.
Fuel Efficiency and Cost Factors
Wider, low-profile tires can reduce rolling resistance on highways, which may improve fuel economy compared to older, taller truck tires used on earlier F-150 models. However, initial purchase price and potential repair costs tend to be higher for larger sizes.
Always weigh the benefits of improved handling and appearance against long-term ownership expenses. Tires with higher speed ratings and reinforced sidewalls typically cost more but can provide better peace of mind for frequent highway use.
Check local retailer promotions and installation fees, because professional mounting and balancing add to the overall investment. Selecting the right size early can save money and time when replacing tires down the road.
Key Recommendations for Tire Selection
- Check the tire information placard and owner’s manual for exact load index and speed rating.
- Keep overall tire diameter within 3 percent of the original specification to protect drivetrain systems.
- Choose all-season or light-truck tires based on your climate and typical driving conditions.
- Have tires professionally mounted and balanced, especially when switching wheel sizes on the F-150 XLT.
- Monitor air pressure regularly to preserve fuel economy, handling, and tire longevity.
FAQ
Reader questions
What is the default tire size on a 2017 Ford F-150 XLT with steel wheels?
The most common OEM size is P235/70R16, though some regions may see P225/75R16. Always confirm by reading the placard or existing tire sidewall.
Can I use P285/65R18 tires on the XLT if I upgrade to 18-inch wheels?
Yes, many 18-inch wheel options on the XLT are designed for P285/65R18 tires, which maintain acceptable diameter overlap with the stock size for speedometer accuracy.
Will larger tires affect my towing capacity on the 2017 F-150 XLT?
Oversized tires can reduce available clearance for the spare and may alter suspension geometry slightly, so verify with Ford specifications and your trailer setup to avoid impacting rated towing capacity.
What tire pressure should I use for different seasons on the XLT?
Follow the pressures listed on the driver-side door jamb, typically around 32–35 psi for normal driving. In cold weather, you may need to adjust slightly to maintain proper handling and fuel efficiency.
