That matters to me because better stability means safer towing and less wear on my trailer.

My Buying Guides on 235 85r16 Trailer Tires
Why I Pay Attention to 235/85R16 Trailer Tires
When I shop for trailer tires, I focus on safety, load handling, and long-term value. The 235/85R16 size is popular because it offers a strong balance of load capacity, stability, and availability. In my experience, this size works well for utility trailers, enclosed trailers, horse trailers, and some RV trailers, especially when I need dependable performance on long hauls.
What 235/85R16 Means
I always start by understanding the tire size. In 235/85R16:
- 235 is the tire width in millimeters
- 85 is the aspect ratio, meaning the sidewall height is 85% of the width
- R16 means it fits a 16-inch wheel
For me, this size usually means a taller tire with good load support and a stable ride for trailer use.
Trailer Tire Types I Consider
When I buy trailer tires, I look at the construction type first:
ST Tires
Special Trailer (ST) tires are what I usually prefer for trailers. They are built specifically for trailer loads and side-to-side stability. I find them to be the safest choice when the tire is made for trailer use.
LT Tires
Light Truck (LT) tires can sometimes be used on trailers, but I only consider them when the trailer manufacturer allows it. In my experience, ST tires are usually the better fit because they are designed for trailer-specific stress.
Load Range and Weight Capacity
This is one of the most important things I check. I never buy trailer tires without confirming they can handle the trailer’s total weight.
Common load ranges I see in 235/85R16 trailer tires include:
- Load Range E
- Load Range F
- Load Range G
I always match or exceed the trailer’s required load capacity. I also make sure to account for cargo weight, water tanks, tools, and any other added load. I prefer a tire with extra capacity rather than one that is just barely enough.
Speed Rating Matters to Me
Even though trailer tires are not usually about high speed, I still check the speed rating. I keep in mind that trailer tires can overheat if driven too fast for too long. For my own peace of mind, I stay within the manufacturer’s recommended speed limit and avoid pushing trailer tires on long hot highway trips.
Bias Ply vs. Radial
I compare both types before making a decision:
Radial Trailer Tires
I like radial tires for most highway use because they usually run cooler and provide better tread wear over long distances. If I travel often, I usually lean toward radial.
Bias Ply Trailer Tires
Bias ply tires can be a good choice for shorter trips or rougher conditions. I find them useful when I need a tougher sidewall feel, but I usually prefer radials for regular towing.
Tread Pattern and Road Conditions
I look at the tread based on where I tow:
- For highway towing, I prefer a tread that wears evenly and runs quietly
- For mixed or rough surfaces, I want a tire with a more durable tread design
- For wet conditions, I look for tread that helps with water evacuation
I do not choose a tire based only on appearance. I focus on how it will actually perform under load.
Build Quality and Brand Reputation
In my experience, brand reputation matters a lot with trailer tires. I look for:
- Strong sidewall construction
- Good reviews from other trailer owners
- Clear load and speed ratings
- Reliable warranty coverage
I usually trust brands that have a consistent track record rather than going with the cheapest option available.
Checking Fitment Before I Buy
Before I order, I always confirm:
- The tire matches my 16-inch wheels
- The width clears the trailer frame and fenders
- The load rating is correct
- The trailer’s recommended tire size matches 235/85R16
I have learned that even a tire with the right size can still be a bad fit if clearance is tight.
Inflation Pressure and Maintenance
I never ignore tire pressure. Trailer tires need to be inflated to the pressure listed on the sidewall or in the trailer manual, depending on the tire and wheel rating. I check pressure before every trip because underinflation can cause heat buildup and failure.
I also inspect for:
- Cracks
- Bulges
–
Final Thoughts
In my view, 235 85r16 trailer tires are a solid choice if I want dependable load support, stable towing, and long-lasting performance. I think the key is matching the tire’s load rating and construction to my trailer’s specific needs so I can tow with confidence. Overall, I’d choose them when I want a reliable balance of strength, safety, and durability for regular hauling.
