Kumho is replacing two familiar SUV and light-truck tires with products designed around a harder promise: useful performance after the new-tire shine disappears.

The Crugen GT Pro succeeds the Crugen HP71 as Kumho’s grand-touring choice for crossovers and SUVs. The Road Venture HT replaces the Crugen HT51, serving pickups, larger SUVs and vans that spend most of their time on pavement.

Both work with gasoline, hybrid and electric vehicles. Kumho says their compounds, tread structures and contact patches were developed to preserve wet grip, stability, comfort and predictable wear throughout the tire’s service life, rather than delivering their best performance only when the tread is fresh.

What the Kumho Crugen GT Pro Replaces

The outgoing HP71 built its reputation on quiet operation, comfort, and solid all-season manners. The Crugen GT Pro keeps that mission but expands it for heavier and increasingly electrified SUVs.

A flatter profile and wider ribs are intended to distribute pressure evenly across the contact patch. Irregular wear can compromise grip and noise performance long before a tire reaches its legal tread limit. Three-dimensional sipes support the tread blocks, while deeper lateral grooves manage water and preserve biting edges as the tire wears.

Kumho claims up to a 20 percent improvement in wear performance. H- and V-speed-rated versions receive a 75,000-mile limited treadwear warranty, while W-rated versions carry 65,000 miles of coverage.

The New GT Pro Sidewall Has a Premium Look

The redesign is not limited to the tread. Kumho added a stylized K symbol representing the company’s technology. Selected sizes use a “laser velvet” micro-machining process that gives lettering and graphics a darker, sharper appearance.

It is a small but relevant detail. Large wheels expose more sidewall, and premium-SUV buyers expect the tire to look considered rather than generic.

Kumho plans to launch the Crugen GT Pro in the United States in September 2026. The U.S. range will cover broad crossover and SUV fitments, with sizes from 16 through 22 inches.

Road Venture HT Replaces the Crugen HT51

The Road Venture HT reached U.S. consumers in June 2026 in more than 40 sizes for 15- through 22-inch wheels. It replaces the Crugen HT51 and brings a claimed 10 percent improvement in tread life.

This is the more truck-oriented tire. Reinforced polyester body plies increase sidewall stiffness, while four circumferential grooves evacuate water. Multi-angle sipes, wider shoulder grooves and interlocking tread features support wet and snow traction.

The Road Venture HT carries the Three-Peak Mountain Snowflake symbol. That means it passed a standardized acceleration test in snow, although it should not be confused with a dedicated winter tire.

P-metric sizes receive a 75,000-mile limited treadwear warranty. LT-metric versions, which face greater load and work demands, carry a 50,000-mile warranty.

The federal UTQG system is a relative wear comparison, not a mileage guarantee.

The Rubber Formula Remains a Closely Held Secret

Both tires contain some natural rubber, but their compounds are primarily synthetic. Modern tire makers blend rubber types with silica, resins, carbon black and other materials to balance grip, heat management, rolling resistance and wear.

Kumho identifies parts of the recipe, including highly dispersible silica, modified butadiene rubber and low-temperature styrene-butadiene rubber. It also uses names such as K-Maxmile and K-Noise Defender for specific performance systems. What Kumho will not provide is the exact formulation, ingredient ratios or processing method that make those elements work together.

That secrecy is understandable. Compound chemistry is valuable intellectual property.

The larger story is not simply that these tires last longer. Kumho is trying to make them behave consistently while they last. A 75,000-mile warranty looks impressive, but stable wet braking, even wear and manageable noise at 40,000 or 50,000 miles determine whether a tire still feels trustworthy. That is the standard these products must ultimately meet.
