4. Sailun S637T ST235/85R16: Heavy Duty Hauler
The Sailun S637T is undeniably built for durability and heavy loads, thanks to its all-steel construction. However, this durable build comes with a trade-off: a significantly stiffer ride compared to more flexible radial-only tires. Our research indicates that this stiffness can transmit more road shock to the trailer, which might be a concern for hauling delicate cargo or for those who prioritize a smoother towing experience.
Trailer owners primarily hauling sensitive equipment, RVs, or anything where vibration dampening is a top priority might find the ride quality of the S637T less desirable. This tire truly shines in demanding commercial applications where maximum load support and puncture resistance outweigh ride comfort considerations.
- Full steel construction in both tread and sidewall for exceptional strength.
- Deep tread depth for extended wear life and improved traction.

6. Power King Towmax STR II ST235/85R16: Dependable Choice
While the Power King Towmax STR II represents an improvement over its predecessors, our deep dive into owner feedback and comparative specifications indicates that it may still exhibit a slightly higher susceptibility to impact damage when traversing particularly rough or unmaintained roads. This isn’t a widespread issue, but consistent reports suggest its sidewall or tread integrity, while good, might not be as impervious as the most solid, heavy-duty options on the market.
Trailer owners who frequently tow on construction sites, gravel roads, or regularly encounter significant road debris might find themselves seeking a tire with more explicit features for extreme impact resistance. For most paved road and light off-road use, however, this tire remains a dependable choice.
- Designed to offer improved resistance to heat and ozone.
- Features a modern tread pattern for reliable traction.
- Constructed for stability and even load distribution.

Frequently Asked Questions
What does ST235/85R16 mean for a trailer tire?
The ‘ST’ designates Special Trailer tire, meaning it’s designed specifically for trailer applications. ‘235’ is the tire’s width in millimeters. ’85’ is the aspect ratio, indicating the sidewall height is 85% of the width. ‘R’ stands for Radial construction, and ’16’ is the diameter of the wheel rim in inches.
What is the typical lifespan of ST235/85R16 trailer tires?
Based on our research and aggregated owner feedback, the lifespan of ST235/85R16 trailer tires can vary significantly. Premium tires, with proper maintenance and use within their load limits, can last 5-7 years, or up to 12,000-15,000 miles. More budget-oriented options might see a shorter lifespan, potentially 3-5 years or around 8,000-10,000 miles, before wear or age necessitates replacement. Factors like load, speed, maintenance, and storage conditions heavily influence longevity.
Can I use passenger car tires on my trailer?
No, based on industry safety standards and manufacturer recommendations, you should not use passenger car (P-metric) or light truck (LT-metric) tires on a trailer. ST (Special Trailer) tires are specifically engineered with stiffer sidewalls, different internal construction, and compounds to handle the unique stresses of trailer use, such as continuous heavy loads and minimal suspension articulation, which differ significantly from a vehicle’s drive axle.
What is a load range and why is it important for trailer tires?
Load range, often indicated by letters like C, D, E, or G, specifies the maximum load a tire can carry at a certain inflation pressure. For ST235/85R16 tires, you’ll commonly see Load Range E or G. It’s critical because it dictates the tire’s capacity to support your trailer’s weight. Using tires with an insufficient load range can lead to overheating, tire failure, and unsafe towing conditions. Always match or exceed your trailer’s Gross Axle Weight Rating (GAWR) with your tire’s combined load capacity.
How often should I check my trailer tire pressure?
We recommend checking your trailer tire pressure before every trip, especially for long hauls. Trailer tires are designed to be run at their maximum recommended cold inflation pressure, which is crucial for handling heavy loads and preventing excessive heat buildup. Underinflation is a leading cause of trailer tire failure, so consistent monitoring is a key safety and maintenance practice.
