Technical Specifications

Understanding the Tire Size

255/70R15C breaks down as follows:

• 255 — the tire’s section width in millimeters, measured sidewall to sidewall.
• 70 — the aspect ratio, meaning the sidewall height is 70% of the section width.
• R — radial construction, indicating the internal body plies run radially across the tire.
• 15 — the wheel/rim diameter in inches the tire is designed to mount on.
• C — a commercial/light-truck load rating designation, indicating the tire is built to carry heavier loads than a standard passenger-car tire of the same size.

The 112/110 in the load index/speed rating designation corresponds to certified load-carrying capacity per tire at the tire’s rated inflation pressure — 112 for single-tire use and 110 for dual-tire (paired) use — as defined by the load index standard. The S speed rating corresponds to a maximum certified speed of 112 mph.

Vehicle & Application Suitability

The Bridgestone Dueler H/T 840 in 255/70R15C is built for:

• SUVs, light trucks, and 4x4s used primarily for highway and on-road driving
• Owners who want a quieter, more comfortable ride without sacrificing durability
• Daily driving, commuting, and light-duty towing or load-carrying
• Occasional use on unsealed or unpaved surfaces

Confirm fitment by matching this size, load index, and speed rating to your vehicle manufacturer’s specifications, along with wheel compatibility.

Who Should Consider This Tire?

This tire is worth considering if you’re:

• An SUV, light-truck, or 4×4 owner in the market for a comfortable, quiet highway tire
• Looking for durability and long wear life for daily on-road driving
• Interested in M+S traction for varied road and weather conditions
• A garage or reseller sourcing a 255/70R15C highway-touring tire for customers

If you need a tire built primarily for off-road or severe winter (3PMSF) use, or a different wheel diameter or load index, this specific listing may not be the right match — confirm your requirements before ordering. For vehicle-specific OE-approved fitment, verify with your vehicle manufacturer.

Tire Size & Fitment Guidance

Before ordering, confirm the following against your vehicle specifications:

• Tire size: 255/70R15C
• Load index/speed rating: 112/110S
• Wheel/rim compatibility for a 15-inch diameter, permitted rim width 7.0″–8.0″ (standard 7.5″)
• Maximum load rating for your intended single or dual application
• Your typical driving conditions (highway, light towing, occasional unpaved surfaces)

If you’re replacing an existing tire, matching the current size, load index, and speed rating helps preserve intended handling and load-carrying characteristics.

Frequently Asked Questions

What does the 255/70R15C size mean? 255 is the section width in millimeters, 70 is the aspect ratio (sidewall height as a percentage of width), 15 is the wheel diameter in inches, and C indicates a commercial/light-truck load rating.

What does the 112/110S load index/speed rating mean? 112 corresponds to the certified maximum load-carrying capacity per tire when used as a single, 110 when used in a dual setup, and S corresponds to a maximum certified speed of 112 mph.

Is this tire suitable for winter driving? It carries an M+S rating for mud and snow traction, but it is not 3PMSF-certified, so it hasn’t passed the standardized severe-snow traction test. It’s best suited to light winter conditions rather than severe snow service.

What rim width does this tire need? The standard rim width is 7.5″, with a permitted range of 7.0″ to 8.0″. Confirm compatibility with your wheel before ordering.
