This listing is for new American Road Star ST Semi Steel ST175/80R13 D/8PLY Tires. Manufacturer part number: AMST001.

The American Road Star ST Semi Steel is a radial ST (Special Trailer) tire for utility trailers, boat trailers, campers and travel trailers. American Road Star is a brand focused on trailer and RV tires.

"Semi steel" describes the casing. In trailer tires, the term generally means steel belts under the tread over a fabric body, as opposed to an all-steel casing with a steel body ply. The fabric body keeps the tire lighter. The steel belts give the tread its strength against punctures and heat. The line runs from 13-inch utility trailer sizes in load range C and D up to 16-inch sizes in load range F (12-ply rating). The ST235/80R16 in load range E carries a 124/120 load index, 3,520 lbs per tire at 80 psi, with an N speed rating (87 mph) and 9/32 inch of tread.

For most utility, boat and travel trailers, a semi steel radial in the right load range is the right match. For heavy fifth wheels and equipment trailers that run near their maximum load, American Road Star also offers an ST All Steel line.

Best-suited for: Utility trailers, boat trailers, pop-up campers, travel trailers, landscape trailers and small car haulers.

Tire Best Features:

Steel belts over a fabric body, a lighter casing built for everyday trailer service.
Load ranges from C (6-ply rating) up to F (12-ply rating) match the tire to the loaded weight.
An N speed rating (87 mph) on rated sizes, above the 65 mph default for unmarked ST tires.
9/32 inch of tread on the ST235/80R16 load range E.
A nondirectional tread that mounts on either side of the trailer.

Description

Load Index

97/93

The load index (LI) is a 2- or 3-digit number that correlates to the maximum amount of weight the tire can carry. For example, a tire with a load index of 87 indicates that the tire can carry a maximum load of 1,201 lbs. In this particularly example, 4 tires (each with a load index of 87) can carry a maximum of 4,804 lbs. Refer to your vehicle owner's manual for the recommended minimum load index.

Speed Rating
A guide to buying tires

Speed rating (SR) indicates the maximum speed the tire can achieve. Higher speed ratings are typically associated with better handling capabilities. Refer to your vehicle owner's manual for the recommended minimum speed rating.

Load Range/Ply Rating
Types of tires

D/8PLY

Ply rating, more commonly referred to as load range, represents the strength and durability of the tire. Higher ratings may indicate your tires can handle heavier loads.

Max Single Load(lbs)

1610

The maximum load this tire will support. Remember to multiply this number by the number of tires installed on your vehicle to get the maximum carrying capacity. This number is directly related to the Load Index.

Max Single Air Pressure(PSI)

The maximum air pressure this tire will support. This does not represent the amount of air pressure your tires should have at all times. Consult with your owner's manual to determine the best air pressure you should use for your vehicle.

Tread Depth

9.0

The amount of tread on the tire. Once the tire is worn to 2/32nds, it is considered fully used and should be replaced at that time. Most tires will have tire indicators in the grooves of the tire to help you determine when the tires are worn down to 2/32nds.

Tread Design

Nondirectional

The pattern of the grooves, lugs, voids, and sipes on a tire's surface. This design affects the tire's traction, handling, and noise characteristics. Common types include symmetrical (uniform pattern across the tire), asymmetrical (different patterns on the inside and outside for varied road conditions), and directional (designed to rotate in one direction for improved wet traction and hydroplaning resistance).

Section Width

6.9

The measurement from sidewall to sidewall.

Overall Diameter

24.0

The height of the tire when fully inflated.
