Staying on top of your tire pressure is an important part of RVing. It ensures that you are maximizing the life of your tires and it can even help to save you money.
The average cost for a new tire is around $500, so keeping your current ones in good shape will give you a sense of relief while out on the road!
In this blog post I will discuss how to check your tire pressure, what factors affect car tire pressure and how to prevent low tire pressure.
How long will travel trailer tires last?
The majority of travel trailer tires will last between 5,000 and 10,000 miles.
However, with proper maintenance (pressure checks at least every couple weeks, rotating the tires every 1,000-1,500 miles) and regular tire pressure checks (every month or so when it’s too cold to check them), you can extend the life of your tires for up to 24 months.
Why Do My RV Tires Keep Going Flat?
If you’ve just bought a new set of trailer tires with brand new tubes, chances are they have a slow leak or your RV Rim is Damaged
Tire pressure drops when the temperature drops (down in the 30s) because your temperature gauge is more accurate when the temperature is higher, not lower. The colder it is outside, the longer you must drive to get your tires up to proper pressure.
Make sure all spare tires on your vehicle carry road-worthy tread if they are used as replacement tires for one of your vehicles.

Can travel trailer tires be aligned?
Yes, They can and this is done by aligning the RF Trailer Axles. If your trailer tires are out of alignment by more than an inch or two, it’s best to have them professionally aligned by a qualified tire shop.
If you need to replace your trailer tires, we recommend that you purchase new ones rather than purchasing used ones. These may be less expensive in initial cost, but they will likely not have the same lifespan as brand new tires and will need to be replaced sooner.
What are the differences between conventional and all-season tires?
Tires have a variety of different types that vary according to material and construction.
For starters, there are all-season tires and conventional tires.
Conventional tires are made with rubber whereas all-season tires consist of rubber and a type of synthetic rubber known as silica. The addition of this material means that not only can all-season tires handle colder climates better, but they also tend to handle wet weather conditions as well.
How often should I rotate my tires?
Tires should be rotated about every 7,500 miles. You definitely want to rotate the tires more often if you have a heavy left/right foot.
The outer edges of the tires actually do most of the work and as you can imagine, get the most wear. Tires should also be rotated if you notice that your car pulls to one side when driving straight.
Generally people don’t rotate their tires often enough and end up with a set of 4 new tires on one side instead of two.
Top 5 Tips for better tire maintenance
1. Keep your tires properly inflated
This will improve your fuel efficiency and help you save money at the pump.
2. Correctly rotate your tires
Rotating your tires on a regular basis ensures even wear, which in turn provides longer tread life and safer driving, all year round! The Michelin Tires website has an easy to use infograph that guides you through the process:
3. Use proper inflator pressure tools when filling up with air
Use of pressure gauges is essential for anyone who cares about their vehicles’ performance, mileage and safety.
4. Replace your tire at the first sign of tread wear
Michelin recommends replacing tires when they have worn down to 4/32″ (0,75 mm). Tire wear can vary across brands and models; important factor is the internal structure of the tire, not just the surface. Even if you can’t visually see the damage, it may be an indicator that a new tire is needed.
5. When possible install winter tires
Winter driving requires special attention on every level – from proper preparation to maintenance during usage, even how you drive plays a key role in maintaining control over your vehicle without compromising safety.
And last but not least – Winter tires are essential! They help to maintain good traction and braking performance by providing better grip on snow and ice, even at sub-zero temperatures.
