The RV Tire Mistake That Ends More Camping Trips Than Almost Anything Else
Why Checking Your RV Tire Pressure Before Every Trip Matters
Quick Answer: How Often Should You Check RV Tire Pressure?
RV tire pressure should be checked before every trip and at least once per month during the camping season. Tires naturally lose air over time, and even slightly underinflated tires can lead to poor handling, uneven wear, reduced fuel economy, and potentially dangerous blowouts.
A five-minute tire pressure check is one of the easiest and most important safety steps every RV owner can take before hitting the road. And sometimes, after a rest stop, if traveling long distances. Let’s explore this a little further.

Why RV Tire Pressure Matters
When preparing for a camping trip, most RV owners focus on packing supplies, loading food, hooking up the trailer, and planning their route.
Unfortunately, one of the most important safety items is often overlooked.
Your tires are the only part of your RV that actually touches the road.
Every pound of your RV’s weight—including your belongings, water, camping gear, and passengers—is riding on a relatively small contact patch between the tire and pavement.
Proper tire inflation helps ensure:
- Better handling
- Improved stability
- More predictable braking
- Reduced tire wear
- Better fuel economy
- Longer tire life
- Improved towing confidence
Most importantly, it helps reduce the likelihood of a tire failure while traveling.
The Common Tire Pressure Mistake Many RV Owners Make
Many RV owners assume their tires are fine simply because they “look okay.” The problem?
You can’t accurately determine tire pressure by looking at a tire.
Modern RV tires can be significantly underinflated and still appear normal.
In fact, many tire-related problems begin long before a tire visibly looks low.
That’s why using a tire pressure gauge is so important.
Checking tire pressure before each trip takes only a few minutes and provides valuable peace of mind before heading down the highway.
Why Underinflated Tires Are Dangerous
Underinflation is one of the leading causes of premature tire failure.
When tire pressure drops below recommended levels, several things happen:
Excess Heat Builds Up
Underinflated tires flex more as they roll.
This creates excess heat inside the tire, which can weaken internal components and increase the risk of failure.
Uneven Tire Wear
Low pressure causes tires to wear differently than intended.
This can shorten tire life and result in expensive replacements sooner than expected.
Reduced Fuel Economy
Your tow vehicle must work harder when towing a trailer with improperly inflated tires.
More rolling resistance means more fuel consumption.
Increased Blowout Risk
A tire blowout can cause significant vehicle damage, create dangerous driving conditions, and quickly end a camping trip.
No one wants to spend vacation time waiting for roadside assistance instead of relaxing around a campfire.
What We See Most Often at Lerch RV’s 32 Service Bays
At Lerch RV, we’ve been helping families create camping memories since 1977.
One thing we’ve learned over the years is that many tire-related issues are preventable.
At our 32-service-bay facility in Milroy, Pennsylvania, we regularly see:
- Underinflated tires
- Uneven tire wear
- Aging tires with plenty of tread remaining
- Tires that have been overloaded
- Damage caused by improper storage
Many owners are surprised to learn that tire age can be just as important as tread depth.
Even tires that look good can develop issues as they age.
That’s why regular inspections and proper inflation are critical for safe travel.
How to Properly Check RV Tire Pressure
Checking tire pressure is simple.
Step 1: Check Tires When Cold
The most accurate reading occurs when tires are cold, before driving.
Driving even a few miles can increase tire temperature and affect pressure readings.
Step 2: Use a Quality Tire Gauge
Digital gauges typically provide the most accurate readings.
Keep one in your tow vehicle or RV so it’s always available.
Step 3: Follow Manufacturer Recommendations
Use the pressure listed by the tire manufacturer or specified for your RV’s loading requirements.
Do not simply guess.
Step 4: Inspect While You’re There
While checking pressure, also look for:
- Cracks
- Bulges
- Uneven wear
- Embedded objects
- Sidewall damage
Step 5: Don’t Forget the Spare
Many RV owners remember the main tires but forget the spare.
The spare won’t help much if it’s flat when you need it.
RV Tire Safety Checklist
Before your next camping trip:
✓ Check tire pressure on all tires
✓ Check tire pressure on the spare
✓ Inspect for cracks or weathering
✓ Look for uneven wear
✓ Verify lug nuts are secure
✓ Confirm tire age
✓ Check valve stems
✓ Inspect suspension components
✓ Verify proper trailer loading
✓ Review tire pressure recommendations
Common Sense Goes a Long Way
RV ownership doesn’t have to be complicated.
Many of the best maintenance habits are simple.
Checking tire pressure isn’t exciting.
It won’t make your camper look better.
It won’t improve your campsite setup.
But it may help prevent one of the most common roadside problems RV owners experience.
Sometimes the smartest camping tips are also the simplest.
A few minutes spent checking tire pressure today could save hours of frustration tomorrow.
