Maintaining the correct pressure is crucial to your RV tire’s health, longevity, and fuel expenditure. Lack of care and improper tire pressure can cause the tires to wear off before time. Setting tire pressure for max efficiency can help you avoid dangerous situations and ensures a smooth journey on a long trip.
If your RV tires are underinflated, you’re not only risking a blowout but also not getting the most efficient gas mileage. On the other hand, if your tires are overinflated, you’re making them work harder than they need to. So how do you strike the perfect balance?
Setting the RV Tire Pressure for Maximum Efficiency
Setting tire pressures for your RV can be a challenging task. There are so many factors to consider, and it’s hard to know where to start. But don’t worry, we’re here to help. You need to know a few things before you start fiddling with your tire pressures.
To set the tires to their maximum efficiency, you must know the RV’s Gross Vehicle Weight Rating (GVWR). It’s the maximum weight your RV can safely carry, and it’s important to know because it will affect your tire pressures.
Next, you need to know your RV’s axle weight ratings. These are the maximum weights your RV’s axles can carry. Also, take note of the RV’s tire size, as it determines the appropriate pressure for the tires.
Balancing the Load
Your RV has its weight but also carries the extra weight of passengers, baggage, and many tools and appliances. Knowing the exact weight is crucial because as you add more weight, you must add tire pressure accordingly for the rig to run more efficiently.
Another matter of attention is not overloading a particular side or axle on your RV. Even weight distribution will help fuel economy, slow tread wear, maintain braking ability, enhance handling, decrease excessive wear of RV components, and more.
Take your RV to your nearest CAT Scale shop to measure the precise weight. No CAT Scale nearby? Don’t worry. The simple rule is the more weight of the RV, the higher the tire pressure will be.

Inspecting the Condition of the Tires
Before setting up tire pressure on your RV, there are a few things that you need to review. As you will be driving around on your rig, it’s not uncommon for unavoidable damage to happen to your tires.
Check your tires when your rig is resting after a ride. There are a few things that you will need to be wary of while taking a look at your tires, such as:
- Rotate the tires completely to get a good view of the entire tire.
- Look around for nails or other objects that might penetrate any of the tires.
- Scan each tire for signs of any sidewall cracking.
- Worn tires are susceptible to punctures and can decrease traction.
- Do not use sidewall treatments and dressings as they can accelerate cracking.
- You will find tread depth indicators between the tread grooves. Change tires before the wear reaches those indicators.
- Check the tire’s temperature. It is not recommended to set your initial tire pressure if the temperature is not “cold.”
- Install a RV TPMS (Tire Pressure Monitoring System) to adjust and monitor perfect tire pressure for max efficiency.

Three Methods for Setting the Tire Pressure
Now that you know everything, it’s time to start setting your RV tire pressures. Here we will discuss three general methods for putting the correct tire pressure.
Don’t Inflate Tires to Their Maximum Pressure
Many people suggest the sidewall numbers as a measurement for setting tire pressure. But the number only indicates the maximum pressure at the maximum weight capacity. So, you don’t need to use max pressure unless you carry max weight.
Also, the climate and road conditions are not always the same as you travel through various places. As a result, the pressure inside your tires fluctuates on its own.
Use Your RV’s Tire Information Sticker
While designing a travel trailer, RV manufacturers made it to a specific Gross Vehicle Weight Rating (GVWR). It’s the highest weight that your rig can carry. The makers also select the right tires that efficiently support the specified weight on the RV.
Moreover, the RV makers determine the recommended tire pressure based on the maximum weight and tire selection. The tire information sticker will have recommendations about tire pressure for max efficiency.
Check the Owner’s Manual
The best way to set RV tire pressure is to consult your RV’s owner’s manual. That will give you the recommended pressure for your specific RV model. If you don’t have the manual, you can usually find the information online or by contacting the manufacturer.
Once you know the recommended pressure for your RV, you can use a tire pressure gauge to check the pressure of each tire. It’s essential to check all four tires, even if they look fine. A small leak can result in significant problems down the road.
If the tires are low, use a portable air compressor to add air until they’re at the proper level. Recheck the pressure after inflating the tires to ensure they’re at the correct level.
Keep two main things in mind when setting RV tire pressure: safety and efficiency. You want to ensure your tires are inflated to the proper level so they can handle the weight of your RV and any cargo you’re carrying. But you also don’t want to overinflate them, which can reduce fuel efficiency and cause premature wear.
Always follow the manufacturer’s recommendation and protocols for max efficient tire pressure for safe travel. If you cannot determine that yourself, take professional help before every new trip.
