Toyo 111310 M655 285/70R19.5 146/144N Load Range H 16-Ply Commercial Truck Tire

The Toyo M655 111310 is a 285/70R19.5 commercial truck tire rated Load Range H, built for medium-duty regional and urban fleet operations that demand durability in mixed on and off-road conditions. Manufactured in Japan at Toyo Tire Corporation's Itami facility, the M655 carries full Three Peak Mountain Snowflake (3PMSF) certification, confirming its tested performance in severe winter conditions. With a 16-ply construction, dual load index of 146/144, and a speed rating of N (87 mph maximum), this tire is engineered to meet the rigorous demands of Class 4 through Class 6 trucks running drive and steer axle positions.

M655 Tread Design and Engineering

The Toyo M655 series features a robust tread compound and pattern developed specifically for regional and urban haulers that encounter both paved roads and unpaved job-site surfaces. The deep 21/32-inch tread depth extends service life while resisting uneven wear across drive and steer axle positions. Wide tread grooves channel water away efficiently, reducing the risk of hydroplaning during rain-soaked urban deliveries.

The M655 is studdable (TSMI No. 15), giving fleet operators the option to add metal studs for improved traction on icy roads in northern climates. Combined with its 3PMSF certification, this tire provides genuine winter-capable performance without requiring a seasonal tire swap. The shoulder design and robust sidewalls resist curbing damage and cuts common in urban stop-and-go routing, keeping the casing in retreadable condition longer.

Size and Load Specifications

The 285/70R19.5 footprint delivers a 10.7-inch section width and a 35.2-inch overall diameter, providing the ground contact patch needed to support heavy loads while maintaining acceptable fuel efficiency for regional routes. The dual load index of 146/144 means the tire can support up to approximately 3,307 lb in single fitment and approximately 3,086 lb per tire in a dual configuration, suited to the typical load demands of Class 4 through 6 trucks.

The recommended rim width is 8.25 inches, with a compatible range of 7.50 to 9.00 inches. Using a rim within this range ensures proper bead seating, correct tire profile, and optimal load distribution. Mounting on rims outside this range can cause handling irregularities or accelerated edge wear and is not recommended.

Retread and Casing Value

Toyo backs the M655 casing with allowances for up to two retreads, extending the economic life of each tire well beyond its first tread wear cycle. Additionally, Toyo includes a $50 retread rubber allowance, reducing fleet operators' net retreading cost per tire. For fleets managing total cost of ownership across large tire inventories, this retread program adds measurable value over the 66-month limited warranty period. Maintaining proper inflation, alignment, and rotation schedules is essential to preserving casing integrity and qualifying casings for retreading.

The company designs and manufactures tires for passenger cars, light trucks, commercial trucks, and motorsport applications, with manufacturing and distribution operations across Japan, the United States, Malaysia, and China. Toyo is recognized for combining advanced rubber compounding research with real-world fleet and performance testing, resulting in tires that balance durability, efficiency, and handling. The M655 commercial truck line reflects Toyo's commitment to the fleet and vocational markets, offering retread-friendly casings and all-weather certifications that lower total operating costs for fleet managers.

Frequently Asked Questions

What vehicles does the Toyo M655 111310 fit?
This tire is designed for Class 4 through Class 6 medium-duty commercial trucks, including regional delivery trucks, utility trucks, and vocational vehicles equipped with 19.5-inch rims. It is suitable for both drive and steer axle positions. Always verify your vehicle's load requirements and rim specifications before purchasing.

What does Load Range H mean?
Load Range H designates a tire with 16 plies of equivalent strength in its construction, capable of carrying heavier loads at higher inflation pressures than lower load range tires. For the M655 in this size, Load Range H allows inflation pressures up to approximately 120 psi and supports the dual load index of 146/144, making it appropriate for heavily loaded Class 4 to 6 trucks.

How does 3PMSF certification differ from a standard all-season rating?
The Three Peak Mountain Snowflake (3PMSF) symbol indicates that a tire has passed standardized acceleration traction testing on packed snow, providing at least 10% better traction than a reference all-season tire. A standard M+S (mud and snow) all-season designation is a self-certification based on tread geometry only, with no independent performance testing required. The 3PMSF certification on the M655 provides fleet operators in northern climates with documented evidence of winter traction capability.

Can studs be installed in the M655?
Yes. The M655 is studdable to TSMI No. 15 specifications. Studs should be installed by a qualified tire technician using the correct stud size and installation torque per TSMI guidelines. Check local regulations before installing studded tires, as some states and provinces restrict or prohibit studded tires during certain seasons or on certain road types.

What rim width is required for the 285/70R19.5?
The recommended rim width is 8.25 inches. The compatible rim width range is 7.50 to 9.00 inches. Mounting on rims outside this range may alter the tire's profile, affect load distribution, and can void the warranty. Using the recommended 8.25-inch rim produces the intended section width and tread contact patch specified in the tire's engineering data.

What is Toyo's retread policy for the M655?
The M655 casing is eligible for up to two retreads under Toyo's warranty program. Toyo also provides a $50 retread rubber allowance per tire. To maintain casing eligibility, the tire must be run at proper inflation pressures, must not sustain impact damage or penetrations through the casing, and should be inspected by a certified retreader to confirm structural integrity before retreading.

What is the speed rating N and does it limit everyday use?
Speed rating N corresponds to a maximum sustained speed of 87 mph. For commercial truck applications governed by federal speed limits and typical fleet speed policies, this rating is fully adequate. Most regional and urban fleet operations do not approach this speed limit, so the N rating does not represent a practical restriction for the intended application of the M655.

What is the difference between single and dual fitment load indices on this tire?
The M655 111310 carries a dual load index rating of 146/144. The first number (146) applies when the tire is mounted in a single configuration on a given axle end, allowing a higher load per tire. The second number (144) applies when two tires are mounted side by side in a dual configuration on the same axle end, reflecting a slight load reduction per tire to account for heat buildup and spacing tolerances. Always reference the correct load index for your specific axle configuration when calculating whether the tire meets your vehicle's load requirements.

Is this tire suitable for off-road or unpaved surfaces?
The M655 is designed for regional and urban on/off-road service, meaning it is capable of handling unpaved roads, gravel access roads, and light job-site terrain in addition to paved highways. It is not a purpose-built deep-mud or rock crawling tire. Its tread design and sidewall strength are optimized for trucks that spend the majority of their time on paved roads but regularly access unpaved driveways, construction sites, or rural routes as part of their routes.
