7. Prepping a Trailer and RV for Fall Storage: Tires and Battery

As a trailer or RV owner, the shift from summer to fall means one thing: preparing your home on wheels for the off-season. Knowing you’re going to be hanging up the keys for several weeks, or even months, there are two key areas to focus your attention: the tires and battery.

With several months of sitting, tires can begin to lose their pressure. Batteries also battle with inactivity, often losing charge at a rapid rate. Need help ensuring your motorhome is travel-ready the next time you hit the road? Read this practical pre-storage guide below.

Why Focus On Tires and Batteries?

Tires and batteries are just two of many important RV components, but how easily you set off on your next adventure depends on them more than most others.

Tire Wear, Tear, and Degradation Don’t Stop

Unlike a motorhome engine and other components, the wear, tear, and degradation of tires don’t stop even when the RV comes to a standstill. Sun exposure, temperature changes, and even the conditions of your storage location can all take a toll. That’s why tire condition and pressure are so important before you fold away your touring maps for the last time.

Check the pressure when the tires are cold, and make sure they aren’t underinflated. Underinflation can cause excessive tire stress once the new travel season begins.
Rather than using a generic pound-per-square-inch (PSI) number when inflating your tires, check the manufacturer’s recommended cold inflation pressure. This extra level of care can serve you well when you’re ready to hit the road again.

Batteries Still Discharge When Sitting

It’s easy to assume that batteries don’t discharge when they’re not being used, but they do. Cold temperatures can affect battery performance, and parasitic electrical loads can continue drawing power!

For many RV owners, the best approach is disconnecting your batteries. However, always follow your motorhome’s battery storage requirements. Many companies recommend:

Fully charging the battery
Disconnecting or removing them to prevent parasitic drain
Storing them in a cool, dry, frost-free location

3-Step RV Tire Storage: What to Check Before Parking

You’ve cooked your last hot dog on the grill, ate your last s’more around a crackling fire, and it’s now time to prepare your RV tires for the colder fall and winter weather ahead. Not sure where to begin? Take these three steps:

Step 1: Check the Pressure

Just as you would check tire pressure during your travels, you should also check it once your summer travels end. Let the tires cool down, find your RV tire manufacturer’s recommended cold inflation pressure, then check every tire. If any are below the recommended pressure, inflate them.

If you need a practical and portable way to inflate underinflated tires before storing your RV or trailer, the WOLFBOX MegaVolt 24Air offers a convenient solution. This 4-in-1 device combines a 4,000A jump starter with a built-in air compressor rated at up to 160 PSI and 45 liters per minute [1], making it useful for adding air to compatible RV, trailer, and vehicle tires without relying on a stationary compressor.

Step 2: Inspect the Tires for Damage

Inspecting your RV’s tires for wear is a great way to avoid a stressful start to the travel season - having to rush around to replace damaged tires!

Look for:

Cracks
Cuts
Uneven wear
Embedded objects
Sidewall damage
Bulges

If you notice any damage that could cause your tires to go flat during long-term storage, consider replacing them.

Step 3: Check the Spare

While the spare tire is out of sight and out of mind, it should be top of mind if there’s a chance you could need it in the future!

Check the spare tire's pressure with a suitable tire pressure gauge, inspect its sidewall condition, and inflate it with the WOLFBOX MegaVolt 24Air if needed. Also, ensure the spare is compatible with your RV and easily accessible.

RV Battery Storage: Maintain, Disconnect, or Remove?

We often expect our motorhome batteries to work as they always have, but that’s not always guaranteed. To remove, disconnect, or maintain…that is the million-dollar question.

Option 1: Maintain the Battery

If your RV is stored somewhere with electrical access, you may want to invest in a battery maintainer that keeps it at an appropriate charge level without you having to check it frequently.

Option 2: Disconnect the Battery

Depending on your battery and RV systems, you may be advised to disconnect the battery to reduce the risk of parasitic drain. Refer to your RV manufacturer’s instructions for best practice.

Option 3: Remove and Store the Battery

Depending on your manufacturer’s guidance and the type of batteries you use in your motorhome, you may find it helpful or necessary to remove the battery and store it in a cool, dry place.

Why Keep a Portable Air Compressor and Jump Starter During RV Storage?

Preparing an RV for seasonal storage helps reduce the risk of tire and battery problems, but it cannot eliminate every issue that may arise after months of inactivity.

A portable air compressor is useful when RV or trailer tires need additional air before storage or when the vehicle returns to service. A jump starter serves a different purpose, providing backup starting power if a compatible vehicle battery becomes depleted.

For RV owners who want to prepare for both situations without carrying separate devices, the WOLFBOX MegaVolt 24Air combines tire inflation and emergency jump-starting in one portable unit. It can be kept in the RV's storage compartment for routine tire maintenance and battery-related emergencies.

Neither function replaces proper tire inspections or battery maintenance. Always follow the vehicle, tire, and battery manufacturers' recommendations.

Ready to tuck away your RV for the colder months? Here’s a handy checklist of what to do before the ‘storage season’ begins:

Tires:

Check every tire’s cold pressure
Inflate the tires to the manufacturer’s recommended pressure with a WOLFBOX MegaVolt 24Air 4-in-1 unit
Inspect tread and sidewalls
Look for uneven wear, bulges, cracks, and other forms of damage
Inspect the spare tire
Protect the tires from extended environmental exposure where possible

Battery:

Charge the battery
Inspect the battery terminals

Follow the storage instructions for your specific battery type
Keep a charged jump starter, such as the WOLFBOX MegaVolt 24Air, as a backup

Pre-Trip Check: What to Inspect When You’re Getting Roadtrip-Ready

Fall and winter are over, and you’re planning your next summer adventure. Here’s what to inspect as you dust off your RV once more:

Tires:

Check the cold pressure
Look for damage
Check for signs of air loss
Inspect the spare tire

Battery:

Confirm the battery’s charge level
Inspect the terminals
Test the RV’s electrical system
If the engine won’t start, use a jump starter, such as the WOLFBOX MegaVolt 24Air, according to its instructions.
