C
- Cap-and-Base Compound
- A dual-layer tread design using a harder top compound for résistance à l'usure et a softer base layer for heat management.

- Fermerd Shoulder
- A tread design where outer ribs sont connected, reducing stone retention et irregular wear on drive-axle pneus.
- NSVAC 119
- Canada Motor Vehicle Safety Standard 119 — Transports Canada's regulation governing pneu de camion commercial construction, labelling, et load ratings. The canadien counterpart to U.S. FMVSS 119; every Hanksugi pneu sold au Canada meets NSVAC 119 requirements.
- CPK (Cost Per Kilometre)
- Total pneu cost divided by total kilomètres driven before removal. The standard parc canadien metric for comparing pneu value — typically expressed in CAD per km à travers new + 3-retread life cycle (~600,000 km).
D
- DOT Code
- A serial number molded into the sidewall identifying the fabricant, production plant, pneu size, et date of manufacture.
- Traction Position
- The powered rear axle(s) of a commercial camion, requiring pneus avec deep, aggressive tread for maximum traction.
- Dual Assembly
- A configuration where two pneus sont mounted side by side on a single wheel end, common on drive et trailer axles.
F
- FMVSS
- Federal Motor Vehicle Safety Standards -- U.S. government regulations governing pneu performance, labelling, et safety. The American counterpart au Canada's NSVAC 119 enforced by Transports Canada.
- Footprint
- The area du pneu tread in direct contact avec the road surface at any given moment under load.
G
- Grooves
- Channels molded into the tread surface to evacuate water, dissipate heat, et provide edges for improved traction.
H
- HATT
- Hanksugi Advanced Pneu Technologie -- a propriétaire ingénierie platform optimizing tread compounds, bead strength, et carcasse geometry.
I
- Inflation Pressure
- The air pressure inside a pneu measured in PSI. Correct inflation est critical for capacité de charge, wear, et fuel efficiency.
- Irregular Wear
- Uneven tread erosion caused by misalignment, improper inflation, mechanical issues, ou using pneus in incorrect positions.
L
- Load Index
- A numeric code indicating the maximum weight a pneu can safely carry at its rated inflation pressure — published in kilograms for canadien NSVAC 119 specifications (e.g., load index 148 ≈ 3,150 kg per tire).
- Load Range
- A letter designation (G, H, J, L) representing a pneu ply-equivalent strength et maximum inflation capacity.
- LRR (Low Résistance au roulement)
- Pneus conçu to minimize energy lost through deformation as the pneu rolls, directly improving fuel economy.
- Lug Pattern
- A tread design featuring deep lateral grooves for aggressive traction, commonly used on drive axles et hors route applications.
M
- M+S (Mud et Snow)
- A sidewall marking indicating the tread meets industry standards for mud et light snow traction. M+S est the minimum legal winter designation in Québec (Dec 1 – Mar 15) et est accepted on designated Colombie-Britannique winter routes (Oct 1 – Apr 30) avec a 3.5 mm tread minimum. Every Hanksugi commercial tread for the marché canadien carries the M+S marking.
P
- Ply Rating
- A legacy measurement of pneu strength indicating load-carrying cord layers. Now replaced by the Load Range designation system.
- PSI
- Pounds per square inch -- the standard unit of measurement for pneu inflation pressure used in North America.
R
- Radial Construction
- A pneu structure where cord plies run perpendicular au direction of travel, providing even wear et flexible sidewalls.
- Retread
- The process of buffing a worn carcasse et applying new tread rubber, extending durée de service at roughly 40% of new-tire cost. Hanksugi guarantees up to 3 rechapages on HS88, HS86, HS86T, et HS26 PLUS canadien carcasses — approximately 600,000 km of total service per carcasse, cutting CPK by ~60% for parcs canadiens.
- Rib Pattern
- A tread design avec continuous circumferential grooves, optimized for long autoroute mileage et even wear on steer axles.
- Résistance au roulement
- The energy a pneu consumes through internal friction as it rolls under load. Lower values translate to better fuel economy.
S
- Sidewall
- The vertical section between the tread et bead containing pneu size, load rating, DOT code, et fabricant markings.
- Siping
- Thin slits cut into tread blocks to create additional biting edges for improved adhérence sur chaussée mouillée et reduced hydroplaning.
- SmartWay
- A U.S. EPA verification program certifying fuel-efficient pneus. Natural Resources Canada references vérifié SmartWay models for parcs canadiens running cross-border lanes — Windsor–Ambassador Bridge–Detroit, Montréal–US Northeast, et Calgary–Vancouver–Seattle.
- Speed Rating
- A letter code (e.g., L = 120 km/h, M = 130 km/h) indicating the maximum sustained speed a pneu est rated to handle safely under load. canadien commercial speed ratings sont expressed in km/h.
- Direction Position
- The front axle of a commercial camion, requiring pneus optimized for precise handling, lateral stability, et even tread wear.
- Stone Ejectors
- Small raised rubber features molded into tread grooves that prevent stones de lodging et drilling into the carcasse.
T
- TPMS
- Tire Pressure Monitoring System -- electronic sensors that continuously monitor et alert drivers when inflation drops below safe levels.
- Remorque Position
- Non-powered axle positions on trailers, requiring pneus conçu to resist lateral scrubbing et minimize résistance au roulement.
- Tread Compound
- The specific rubber formulation du tread surface, conçu to balance résistance à l'usure, traction, et heat dissipation.
- Tread Depth
- The distance de the tread surface au bottom du deepest groove, measured in 32nds of an inch ou millimetres. hiver canadien-tire regulations use mm — Québec requires 3.5 mm minimum de Dec 1 – Mar 15.
- Three-Peak Mountain Snowflake (3PMSF)
- A sidewall symbol certifying the pneu meets severe snow-traction performance. Required on designated Colombie-Britannique winter routes de Octobre 1 through Avril 30 et the strongest winter-traction designation recognised by Transports Canada.
- Three-Retread Guarantee
- Hanksugi's canadien carcasse guarantee: up to 3 rechapages on HS88, HS86, HS86T, et HS26 PLUS carcasses for approximately 600,000 km of total durée de service — cutting fleet CPK by roughly 60% versus single-life pneus.
- Transports Canada
- The federal regulatory department overseeing commercial vehicle safety, incluant NSVAC 119 pneu construction et labelling standards, GVWR compliance, et cross-border equipment requirements for camions operating au Canada.
U
- UTQG
- Uniform Pneu Quality Grading -- a DOT rating system measuring treadwear, traction, et temperature resistance (primarily for passenger tires).
V
- Virgin Tire
- A marque-new pneu that has never been used ou rechapé, also referred to as a new ou original carcasse.
