Hi run H180 Trailer Tire
Count on dependable towing with the Hi run H180, a bias-ply ST trailer tire built for steady tracking, even wear, and confident load support. The ribbed tread helps the trailer track straight behind the tow vehicle, and a heat resistant compound stands up to stop-and-go work and weekend hauling. Whether you tow a utility, cargo, or boat trailer, the H180 delivers practical durability and value when paired with the right size, load range, and inflation. Choose your fitment, mount on approved trailer wheels, and tow with confidence.
Specifications and Construction
The Hi run H180 is an ST, Special Trailer, tire with a bias-ply casing built for durability under load. Its ribbed tread promotes straight line stability and helps resist irregular wear at proper inflation. Listings typically note tubeless fitment and multiple load ranges for single and tandem axle trailers, and the sidewall shows the speed symbol plus maximum load and psi. The H180 is for trailer service only, so match it to an approved wheel width, maintain the recommended cold inflation pressure, and torque lug nuts to the hub maker's spec.
Sizes and Fitment
Check your trailer's VIN placard or owner's manual for the required size and load range, then match it to the Hi run H180. Popular sizes include ST205/75D14 and ST225/75D15 in multiple load ranges. The letter D in the size indicates bias-ply construction, and ST denotes trailer use. Replace tires in pairs on each axle, avoid mixing sizes or constructions on the same axle, and verify fender and suspension clearance after install. When in doubt, stick with the size and load range specified by the trailer maker and confirm your wheels are rated for the required psi.
Load Range and Ply Rating Explained
Trailer tire load range letters indicate strength and maximum pressure and load, not the number of plies. Load Range C, often shown as 6PR, and Load Range D, often shown as 8PR, are ply rating equivalents used as shorthand. In the same size, a D, 8PR, H180 usually carries more weight at a higher psi than a C, 6PR. Match load range to your trailer's GAWR and never exceed the lowest rated component, and run the recommended cold inflation to achieve published load capacity and control heat.
Best Uses and Towing Tips
The Hi run H180 suits utility, landscape, cargo, and boat trailers where rugged, value focused performance matters. Bias-ply construction pairs well with frequent stop-and-go use, yard work, and short to medium towing. Keep loads balanced front to back and side to side, maintain proper tongue weight, and inflate to the tire's specified cold psi before each trip. Re-torque lug nuts after the first 25-50 miles on newly mounted tires and on a regular schedule. Inspect for cuts, bulges, or punctures, and replace tires that show cracking, uneven wear, or are past their service age.
Hi run H180 vs. Radial Trailer Tires
Compared with radial trailer tires, the bias-ply Hi run H180 emphasizes rugged casing support and value. Bias designs often deliver firmer sidewalls for stability, which suits utility and work trailers that run at moderate speeds on mixed surfaces. Radial trailer tires typically run cooler on long highway drives and may ride more smoothly. Choose based on how you tow, long distance highway use often favors radials, while local hauling, yard work, and budget priorities can favor the H180's bias-ply build. Never mix bias and radial tires on the same axle, and match all tires by size and load range.
Reviews and Owner Feedback
Owners often highlight the Hi run H180's straightforward value, stable tracking, and reliable performance when matched to the correct load range and inflation. Many use it on utility and boat trailers and like the predictable towing manners from the ribbed tread. As with any trailer tire, durability depends on keeping loads within ratings, maintaining proper psi, and storing tires away from sunlight and ozone. Some reviews note that under inflation or prolonged overload leads to heat and wear issues, which underscores the need to follow the sidewall and trailer placard limits.
Pricing and Availability
The Hi run H180 is priced for practical, everyday trailer service. Final cost varies by size and load range. Select your size to check stock, then review lead times and shipping at checkout. For best value, replace tires in axle pairs and consider new valve stems and mounting services. Need help selecting? Share your size, load range, and axle ratings for a fitment recommendation.
