An important point of consideration is when using two different size tires, the load has to be no more than the capacity of the lowest rated tire. With this substantial difference with both weight capacities and inflation levels,
the chances of inadvertently overloading on the smaller side tire is quite possible
.

What tires does my travel trailer need?
Load Capacity
In order to properly manage the weight of your RV trailer,
all tires must be identical in size and the combined capacity of the tires must equal or exceed the Gross Vehicle Weight (GVW) of the axle
. In fact, the combined capacity of all of the tires should exceed the loaded trailer weight by 20 percent.
How do I know what wheels fit my trailer?
If the trailer has no wheels, or you think the ones that are on it are incorrect, measure the bolt circle (the distance between the center of the hub and the center of one bolt multiplied by 2) and the inner wheel well carefully to determine the overall size it can accommodate when you include tires, and check to see …
Are Bigger tires better for trailers?
Simple physics:
Wider tires = more road resistance = more power required to pull = lower MPG while towing
. Trailer builders use smaller tires to save weight and cost.
Why do trailer tires wear out so fast?
That said, rapid or significantly uneven trailer tire wear can be caused by:
Riding with the wrong tire pressure
. Exceeding your tires’ load capacity. Trailer misalignment or bent wheels from hitting curbs, potholes or debris.
Are all RV tires the same size?
Size Matters
There are multiple different types of RV’s, and there are multiple different types of tires that each of those RV’s may use, so in the case of RV tires:

Can I use LT tires on my travel trailer?
LT tires are intended for vehicles that generate stress with heavy loads—pickups, commercial vans, and heavier SUVs. Their stability makes them ideal for mounting on a tow vehicle. Over the last couple of years,
some camper trailer makers, including high-end manufacturer Airstream, have offered LT tires as an option
.

What vehicles use a 5×4 75 bolt pattern?
The answer:
many classic muscle cars

Does wheel size matter on a trailer?
You’ll need to ensure they match the trailer hub.
A larger rim and tyre size may actually place more stress on the axles and springs
. If you replace the existing wheels with larger ones, the trailer might not sit level with your car, putting stress on the towball.
What is the most common trailer tire size?
For example, a common trailer tire size is
ST225/75R15
. ST stands for special trailer and indicates that this tire is designed to be used on a trailer. 225 is the width of the tread in millimeters. 75 is the height of the sidewall represented as a percentage of the tread width.
Should I run my trailer tires at max pressure?
It’s really important not to overload trailer tires
. Overloading tires can cause premature wear and increase the risk of tire failure. The “Max. Load” information stamped on the sidewall indicates a tire’s load capacity when it’s inflated to the maximum PSI.
Why do RVs have such small tires?
RVs have small tires because
a smaller tire means less intrusion into the undercarriage space and wheel wells
(=more space for you inside). Because of this, the RV retains more stability as well. Another reason these tires are so small is likely due to manufacturers cutting costs by using smaller tires during assembly.
Do trailer tires need to be balanced?
Since the primary duty of a trailer tire is supporting a vertical load, rather than gripping an automobile through turns,
trailer tires do not have to be dynamically balanced
like passenger car tires do. Steering and cornering are less of a concern on a trailer tire than they are on an automotive tire.
How do you stop a travel trailer from Porpoising?
Most of the time when a tow setup is porpoising with a weight distribution system all you have to do is
add a bit more spring bar tension
to minimize the porpoising. With an Equalizer system you would need to angle the spring bars down further to add the additional tension.
Is Load Range D better than C?
The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel.
The D rated tire has a higher capacity
.
Can you use truck tires on an RV?
Expert Reply:
Light truck tires (LT) are sometimes used in RV applications but generally not on utility trailers
