Increasing Tire Size: Pop-Up Camper Modifications

Increasing the tire size of your pop-up camper can have several benefits, including improved handling and stability, especially when driving at higher speeds. When choosing a larger tire size, it is important to consider factors such as the weight capacity, speed rating, and compatibility with your camper's axle and wheel wells. It is also crucial to ensure that the tires are specifically designed for trailers, as they need to carry a much bigger load than regular car tires.

Check the weight capacity of your current tires

When increasing the tire size on your pop-up camper, it is crucial to check the weight capacity of your current tires to ensure safety and optimal performance. Here are some detailed instructions to guide you through the process:

First, locate the load index or load rating of your current tires. This information can usually be found on the sidewall of the tire, often indicated by a combination of letters and numbers. The load index represents the tire's maximum weight-carrying capacity and is crucial for vehicle safety. A higher load index indicates a higher load-carrying capacity. For example, a tire with a load index of 92 can support 1,389 pounds at maximum air pressure.

Next, refer to the tire load index chart to understand the weight capacity of your tires. Multiply the load index by the number of tires on your vehicle to determine the total weight capacity. For instance, if your tire has a load index of 84, it can support 1,102 pounds. Multiplying this by four tires gives a maximum load-carrying capacity of 4,408 pounds for your vehicle.

Now, compare the weight of your pop-up camper and any additional equipment you carry to the total weight capacity of your tires. Ensure that the weight of your camper and gear does not exceed the tires' load-bearing capacity. Overloading your tires can lead to premature wear, decreased fuel efficiency, and dangerous blowouts.

When choosing new tires for your pop-up camper, it is essential to select tires with a higher load index or load rating than your current tires to accommodate the increased tire size. Refer to your owner's manual to find the recommended tire size and load rating for your specific vehicle. You can also consult tire experts or mechanics for guidance in choosing the appropriate tires for your needs.

Remember, the weight capacity of your tires is a critical factor in ensuring the safety and performance of your pop-up camper. Taking the time to understand and check your tire's load index will help you make informed decisions when upgrading your tires and ensure a smooth and safe camping experience.

Check the speed rating of your tires

When increasing the tire size on your pop-up camper, it is crucial to check the speed rating of your tires. This is an important safety consideration, as using tires with an inadequate speed rating can lead to accidents.

The speed rating of a tire indicates the maximum speed at which it can safely operate. It is typically found on the sidewall of the tire, and it is represented by a letter, such as "L", "M", "N", "Q", or "R", each corresponding to a specific speed. For example, a tire with a speed rating of "L" has a maximum speed of 75 mph, while a tire rated "Q" can handle speeds up to 99 mph.

When upgrading your pop-up camper tires, ensure that the speed rating matches or exceeds your driving needs. If you frequently drive at higher speeds, opt for tires with a higher speed rating to ensure safety and performance. Additionally, consider the weight of your camper and the terrain you'll be traversing, as these factors can impact the required speed rating.

It's worth noting that trailer tires, including those on pop-up campers, are typically limited to a maximum speed of 65 mph. However, some users have reported cruising at speeds between 60 and 70 mph without issues. If you plan to drive faster, it is recommended to choose tires with a higher speed rating, such as the Kumho 857 tires, which have a speed rating of "Q" for 99 mph.

When in doubt, consult a professional or refer to the manufacturer's specifications for your specific camper model to ensure you select the appropriate tires for your vehicle. Remember, choosing the right speed-rated tires for your pop-up camper will enhance your safety and peace of mind while on the road.

Check your wheel bearings

To increase the tire size of your pop-up camper, you will need to check your wheel bearings. This is a crucial step to ensure the safety and performance of your camper. Here is a detailed guide on how to check and maintain your wheel bearings:

Step 1: Remove the Wheel

Use an impact wrench to remove the lug nuts, and then slide off the wheel. This will give you access to the inner components, including the wheel bearings.

Step 2: Remove the Dust Cap

Use channel locks or a flathead screwdriver to remove the dust cap. The dust cap covers and protects the spindle and castle nut (or spindle nut).

Step 3: Remove the Cotter Pin and Castle Nut

Straighten and remove the cotter pin using needle-nose pliers. The cotter pin secures the castle nut in place. After removing the pin, unscrew the castle nut from the spindle.

Step 4: Remove the Outer Bearing

Jiggle the hub slightly to loosen the outer bearing. In most cases, this will allow you to remove the outer bearing by hand. There may also be a washer between the castle nut and outer bearing, which you should set aside with the castle nut.

Step 5: Remove the Inner Bearing and Grease Seal

Pull the hub off the spindle and place it with the wheel studs facing up. Use a wooden dowel and a mallet to tap out the inner bearing and grease seal. Alternatively, you can pry out the grease seal with a flathead screwdriver and remove the inner bearing by hand.

Step 6: Clean and Inspect the Bearings

Wipe down the bearings, castle nut, and spindle with paper towels to remove excess grease. Inspect them for any signs of damage, including pitting, scratches, excessive wear, discoloration, or dents. If any damage is found, discard and replace the affected components.

Step 7: Clean the Inner Races

Wipe away any excess grease from inside the hub and inspect the inner races for damage. If they appear to be in good condition, you can reuse them. If there is any sign of damage, they will need to be replaced.

Step 8: Repack the Bearings with Grease

Use a high-quality grease designed for bearings. Place a generous amount of grease in your palm and use the wide end of the bearing to scoop it up. Turn the bearing and repeat the process until it is completely filled with grease. Flip the bearing over and repeat for the other end.

Step 9: Clean and Grease the Hub

Clean the inside of the hub to remove any old grease or buildup. Apply a generous amount of grease to the inner race.

Step 10: Reinstall the Inner Bearing and Grease Seal

Place the newly packed inner bearing into the hub, followed by the new grease seal. Tap gently with a wooden mallet until the seal sits flush, and wipe away any excess grease.

Step 11: Clean and Inspect the Spindle

Remove any grease or debris from the spindle and check for any nicks or wear. If the hub was difficult to remove or there is any damage, the spindle may need to be replaced.

Step 12: Reinstall the Hub, Outer Bearing, and Castle Nut

Grease the outer race and slide the hub back onto the spindle. Take care not to damage the spindle or grease seal. Reinstall the outer bearing and, if applicable, the washer. Thread the castle nut onto the spindle and tighten until snug.

Step 13: Adjust and Secure the Castle Nut

Rock the hub and push it in to ensure it is fully seated. If necessary, tighten the castle nut again until snug. The wheel should rotate freely without excessive play. Loosen the castle nut slightly (about a quarter turn) to find the perfect adjustment. Reinsert the cotter pin and bend the end to lock it into place.

Step 14: Reinstall the Dust Cap or Bearing Buddies (Optional)

You can reinstall the dust cap at this point. Alternatively, you can use Bearing Buddies, which make it easier to grease and maintain your bearings. Bearing Buddies replace the dust cap and allow for easy grease additions.

By following these steps, you can ensure that your wheel bearings are in good condition and properly maintained. This will help prevent issues such as increased friction, overheating, and seizing of the wheel bearings. Remember to refer to your camper's user manual for specific instructions and always perform regular maintenance checks before embarking on any trips.

Check your valve stems

When increasing the tire size on your pop-up camper, it is crucial to pay attention to the valve stems. Here are some detailed instructions to guide you through the process:

Understanding Valve Stems:

Valve stems are an essential component of your tires, responsible for maintaining air pressure. They are the small metal tubes protruding from the wheel that allow air to enter and exit the tire. Over time, valve stems can become worn or damaged, leading to air leaks.

Check for Leaks:

Before assuming that your valve stems need replacement, it is important to confirm that they are indeed leaking. Remove the valve stem cap and listen carefully. If you hear air escaping or feel a rush of air, it indicates a leak. Another method is to apply a soapy water solution to the valve stem; if bubbles form, it confirms a slow leak.

Inspect the Valve Stem:

Use a valve stem tool (also known as a valve core tool) to check the tightness of the valve stem. If it is loose, tightening it and adding more air to the tire may solve the problem. However, if the valve stem is tight, you will need to remove it. This can be done using the valve stem tool by pulling out the stem. Be cautious, as the sudden release of air may cause the stem to shoot out.

Clean the Valve Stem Threads:

Once the valve stem is removed, inspect the old core threads for any signs of corrosion or damage. If present, use the tap end of the valve core tool to clean the interior threads of the valve stem gently. This step is crucial to ensure a proper seal when installing the new valve stem.

Install a New Valve Stem:

After cleaning, it's time to install a new valve stem core. Screw in the new valve stem, being careful not to over-tighten it, as this can strip the threads. Snug is sufficient. Remember to reinstall the valve stem cap as well to keep dirt out and prevent future leaks.

Test for Leaks:

After installing the new valve stem, refill the tire with air and check for any further leaks. You can use the soapy water solution again by spraying it on the new valve stem. If no bubbles form, your leak issue should be resolved.

Maintain and Inspect Regularly:

To prevent future issues, it is important to maintain and inspect your valve stems regularly. Keep a tire pressure gauge handy and check your tire pressure at least once a month. Additionally, always ensure that your valve stem caps are in place to protect the valve stems from dirt and debris.

By following these steps, you can effectively address any issues with your valve stems when increasing the tire size on your pop-up camper, ensuring a safe and enjoyable camping experience.
