This article is your comprehensive guide to the Ford Ranger Raptor 37-inch tire conversion, designed to make your truck the ultimate off-road beast. We will discuss everything you need to consider before making the jump to these larger tires. This upgrade will make your Ranger Raptor the envy of every off-road enthusiast. Trust me, it's worth it, but let's make sure you do it right.

First off, why even bother with 37-inch tires? Well, the benefits are pretty compelling. The most significant advantage is increased ground clearance. Those extra inches make a massive difference when you're navigating rough terrain, allowing you to clear obstacles that would stop a stock Raptor in its tracks. You'll be able to tackle bigger rocks, deeper ruts, and more challenging trails. It is all about the off-road capability. With the stock tires, the Ranger Raptor is already an incredibly capable truck, but the larger tires take it to a whole new level. Besides the enhanced off-road performance, the 37-inch tires also dramatically change the look of your truck. They fill out the wheel wells, giving the Raptor a more rugged and imposing stance. It just looks cool, and who doesn't want their truck to look seriously badass? The larger tires also often offer better traction due to the increased surface area, which improves grip on various surfaces like sand, mud, and snow. That means you will have a more confident and stable ride off-road. However, these benefits come with some considerations, which we'll explore below, to make sure you get the most out of your 37-inch upgrade.

Choosing the Right 37-Inch Tires

Alright, let's talk tires. Not all 37-inch tires are created equal, and choosing the right ones for your Ford Ranger Raptor is crucial. The market is filled with options, so you need to consider a few key factors. First, consider the tire type. There are three main categories: All-Terrain (AT), Mud-Terrain (MT), and Hybrid Terrain. All-Terrain tires are a great choice if you spend most of your time on the road but still want good off-road performance. They offer a good balance of on-road comfort, noise levels, and off-road traction. Mud-Terrain tires are designed for serious off-roading. They have aggressive tread patterns that provide excellent grip in mud, sand, and other loose surfaces. However, they can be noisy on the road and may wear faster. Hybrid Terrain tires bridge the gap between AT and MT tires, offering a good compromise of on-road manners and off-road capability. They are a good option for those who want the best of both worlds. Next, the tread pattern is important. It directly impacts the tire's performance in different conditions. Aggressive tread patterns with large voids are best for mud and loose terrain, while more tightly packed tread patterns are better for on-road use and offer better wet-weather performance. Also, the tire construction matters. Look for tires with strong sidewalls, which will help protect against punctures and improve off-road durability. Sidewall plies will affect the tire's ability to resist cuts, abrasions, and punctures, and it also contributes to the tire's load-carrying capacity. Consider the load rating of the tires to ensure they can handle the weight of your truck, especially if you add accessories like a winch or heavy bumpers. Choose tires from reputable brands known for quality and durability, such as BFGoodrich, Nitto, Toyo, and Mickey Thompson. Research reviews and ratings to see what other Raptor owners are saying about different tires. Finally, consider your driving style and typical terrain. If you do a lot of highway driving, prioritize on-road comfort and noise levels. If you are mainly off-roading, focus on traction and durability.

Modifications and Considerations for 37-Inch Tires

So, you have picked out your new tires. Now comes the important part, making sure they actually fit your Ford Ranger Raptor and function correctly. Installing 37-inch tires is not a direct bolt-on operation. You will most likely need to make some modifications to your truck to accommodate the larger tires. First on the list is a lift kit. The Raptor already has a good amount of suspension travel compared to other trucks, but a lift kit will provide the necessary clearance to prevent the tires from rubbing against the fenders, bumpers, and other components. A lift kit will raise the entire truck, providing more ground clearance and allowing for the larger tires. The amount of lift you need will depend on the specific tires and wheel offset you choose. You can often get away with a leveling kit or a small lift kit (around 2-3 inches). But with 37-inch tires, you might need a larger lift (3-4 inches) to ensure sufficient clearance during articulation. Next, you need to consider wheel offset and backspacing. These measurements determine how far the wheels sit outwards or inwards. Proper wheel offset is crucial for avoiding rubbing issues. Wheels with a more negative offset will push the tires further out, which can provide more clearance but might also increase the chance of rubbing. Wheel backspacing is also essential, and it measures the distance from the wheel's mounting surface to the inside edge of the wheel. Another critical modification is trimming the fenders and bumpers. Even with a lift kit and the correct wheel offset, you might still experience rubbing, especially during off-road articulation. Trimming the fenders and bumpers is often necessary to provide extra clearance. This can involve cutting away some of the plastic or metal and may require some professional bodywork. Also, you should address the speedometer and odometer recalibration. The larger tires will affect your speedometer and odometer readings. Your speedometer will read slower than your actual speed, and your odometer will record fewer miles than you have actually traveled. Recalibrating these instruments ensures that your speed and mileage readings are accurate. You can do this using a programmer or by having it professionally calibrated. Finally, think about your gearing. The larger tires will change your truck's gear ratio, making it feel less powerful, especially from a stop. This is because the larger tires increase the effective final drive ratio. To restore your truck's performance, you might want to consider re-gearing your axles. This involves replacing the ring and pinion gears in your differentials with gears that provide a more appropriate ratio for the larger tires. This can be a complex and expensive modification, but it can make a big difference in how your truck drives. Re-gearing will not only restore your acceleration, but it will also help with fuel economy and prevent excessive strain on your transmission.

Performance and Driving Experience

Once you have the 37-inch tires installed, you will immediately notice the difference in the way your Ford Ranger Raptor handles. The most obvious change will be increased ground clearance, allowing you to conquer obstacles that you could not before. Your truck's approach, departure, and break-over angles will also improve, making it more capable on technical trails. The larger tires will also provide better traction, giving you more grip in various conditions. You'll feel more confident on loose surfaces, and your truck will be less likely to get stuck. However, there are some trade-offs to consider. With larger tires, the truck's acceleration will be slower, especially from a stop. This is due to the increased rotational mass and the change in the gear ratio. Your fuel economy will also decrease. The larger tires are heavier, which puts more strain on your engine and transmission. The added rolling resistance also reduces fuel efficiency. In addition, your truck's on-road handling may change. The larger tires can make the steering feel less responsive, and the truck might be more prone to body roll. The ride quality may also be affected. The larger tires may cause the ride to be firmer, and you might feel more bumps and imperfections in the road. However, these trade-offs are often worth the benefits for off-road enthusiasts. The increased off-road capability and the aggressive look of the truck more than compensate for the slight decrease in on-road performance. After the conversion, take some time to get used to the new driving characteristics. The truck will feel different, and you will need to adjust your driving style accordingly. This will help you get the most out of your upgraded Raptor. Remember to drive safely and within your limits. Also, regularly inspect your tires for wear and tear, and check your tire pressure to ensure optimal performance and safety. With proper care and maintenance, your Raptor will be ready for any adventure.

Long-Term Maintenance and Considerations

Upgrading to 37-inch tires on your Ford Ranger Raptor is a significant investment, so it is essential to consider the long-term maintenance implications. Larger tires place more stress on various components of your truck, which means you need to pay attention to certain areas. First, expect accelerated tire wear. 37-inch tires, especially mud-terrain tires, tend to wear faster than smaller tires. Regular tire rotations and proper tire inflation are essential to maximize tire life and ensure even wear. You should also regularly inspect your tires for any signs of damage, such as cuts, bulges, or uneven wear. Next, there is suspension wear. The increased weight and stress from the larger tires can accelerate wear on your suspension components, such as shocks, struts, ball joints, and tie rod ends. Inspect these components regularly and replace them as needed. Consider upgrading to heavy-duty suspension components to handle the added stress. Also, pay attention to your drivetrain. The larger tires increase the load on your drivetrain components, including the axles, differentials, and transmission. Check your differential fluid levels regularly, and consider changing the fluid more frequently than recommended. If you have re-geared your axles, make sure the gears are properly broken in, and follow the manufacturer's recommendations for maintenance. Another crucial thing to consider is the impact on your brakes. The larger tires increase your truck's stopping distance. Make sure your brakes are in good condition and consider upgrading to larger brake rotors and calipers for improved stopping power. Regularly inspect your brakes and replace worn pads or rotors as needed. Furthermore, expect an impact on your fuel economy. The larger tires, combined with any lift kits or re-gearing, will affect your fuel consumption. You may experience a decrease in miles per gallon (MPG). It is also important to consider the legal aspects. Some states have regulations on tire size and lift height. Make sure your modifications comply with local laws and regulations. You should also consider insurance implications. Inform your insurance company about your modifications, as they may affect your coverage or premiums. Finally, don't forget to maintain your truck's overall condition. Regular maintenance, including oil changes, filter replacements, and fluid checks, is more important than ever. These things will keep your Raptor running smoothly and help prevent any unexpected problems.
