The Sumitomo ST 918 225/70R19.5 F/12PLY Tires is a Commercial Truck - Drive tire. Manufacturer part number: 5531781. The ST918 is engineered for the rough metro environment. Its center island tread elements are designed for great traction in wet or dry maneuvers. It features a radical shoulder ribs that act like traction bars and stabilizes the tread for longer life in commercial service. Its all steel casing construction resists punctures, increases vehicle stability and contributes to more retread cycles. Its curbing ribs help shield the casing from sidewall damage and the multi-phase shift tread pattern minimizes tire noise. The reinforcing bridges of rubber tie together the tread package for vehicle stability and resistance to irregular wear. Its computer designed tread pattern and application specific compounds deliver vehicle stability, long mileage and excellent traction. ST918 gives the traction needed to get the job done in bad weather.

Description

Sidewall

Not Available

Describes the sidewall appearance. Examples: BSW= Black Side Wall, WSW = White Side Wall, OWL = Outlined White Letters.

Load Index

Not Available

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

Not Available

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

F/12PLY

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.

UTQG

Not Available

To help consumers evaluate their tires, the U.S. National Highway Traffic Safety Administration (NHTSA) created the Uniform Tire Quality Grading System (UTQG). The UTQG rates tires are rated on their tread-wear, traction performance, and temperature resistance. The grade for each of these can be found on the sidewall of your tire (except for winter tires and certain light truck tires).

Max Single Load(lbs)

3640

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

20.0

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).

Rim Width Range

6.0-6.75

The approved wheel rim width range this tire will support.

Measured Rim Width

6.75

The recommended wheel width as recommended by the tire manufacturer to get the best wear us performance for this tire.

Section Width

8.8

The measurement from sidewall to sidewall.

Tread Width

Not Available

The measurement from one side of the tread to the other side of the tread.

Overall Diameter

32.1

The height of the tire when fully inflated.

Best Value

"These Sumitomo tires cost much less than the leading brands, yet seem to be just as durable and long-lasting. I found the lowest price on them at Tires-Easy (especially when figuring in the fast, free shipping), and am very happy with my purchase."

Best front end tires

"Absolutely the best tires for the front end of a f450, f550. Drive square, wear square. No hunting, good traction off the pavement. Run good on the back end, too."

Feb 16, 2020 by Burt

Only about 500 miles but great so far

"Great price and good pulling tire"

Feb 18, 2021 by Todd

Great tires

"I’m pleased with them so far, I use them commercially towing a 40 ft trailer and nothing but good to say, the tread has big enough tread that they don’t pack full of rocks and are wearing great, snow traction is awesome"
