The Blackhawk BTR55ST ST235/85R16 G/14PLY Tires is a Commercial Truck - Trailer tire. Manufacturer part number: 5546882V.

The Blackhawk BTR55ST is a heavy-duty all-steel ST trailer tire in load ranges F and G. It is for the heaviest trailers: big fifth wheels, travel trailers, car haulers and equipment trailers that need more capacity than a load range E tire offers.

"All-steel" means steel cords in the body plies as well as in the belts. A light-duty ST tire typically uses polyester body plies, and the steel casing is what lets this tire carry heavy loads at high inflation pressure without excessive flex. Less flex means less heat, and a cooler casing lasts longer. The ST235/80R16 in load range G carries 4,079 lbs per tire on a single axle (load index 129/125). The ST235/85R16 carries 4,409 lbs (132/127). Four wide circumferential grooves drain water from the footprint for wet-road stability.

Two numbers help you get its full capacity. First, the wheels: load range G sizes run at 110 psi, so match them with wheels stamped for that pressure. Second, the speed rating: most sizes are rated L (75 mph) and some M (81 mph), the ceiling for a loaded trailer. It is built for free-rolling trailer axles only.

Best-suited for: Fifth-wheel trailers, large travel trailers, toy haulers, car haulers, gooseneck and equipment trailers.

All-steel construction carries heavy loads at high pressure with less casing flex and heat.

Description

Load Index

132/127

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

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

G/14PLY

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)

4400

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)

110

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

12.0

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

9.3

The measurement from sidewall to sidewall.

Overall Diameter

31.7

The height of the tire when fully inflated.
