The Kumho Solus TA51+ is a touring all-season tire for passenger cars, positioned in the mid-range comfort segment. It is the successor to the Solus TA51 and is marketed in Korea under the name Solus Advance. The tire was developed to address the chunking issue reported on the TA51 and to improve mileage, wet braking, and cabin refinement. It carries a treadwear rating of 600 and is engineered for year-round use on sedans, crossovers, and firm-suspension vehicles where ride compliance is a priority.

Features & Benefits

• All-season compound: Delivers over 10% longer mileage versus the predecessor, supported by a 600 treadwear rating.
• D chamfered tread blocks: Reduce irregular wear and improve sipe retention, addressing the chunking problem that affected the TA51.
• Optimized rolling resistance: More than 20% lower than the previous generation, contributing to fuel efficiency.
• Dimple-pattern noise reduction: Disperses pattern noise across the tread grooves, lowering cabin resonance.
• Asymmetric tread design: Balances dry grip, wet evacuation, and even wear across the contact patch.
• Compliant sidewall: Softens ride harshness on firm-suspension vehicles, improving comfort on broken pavement.
• Updated sidewall graphics: New visual identity for the Solus Advance line.

Year Released

The Solus TA51+ launched on April 1, 2025, in the Korean market. It replaces the Solus TA51, which was discontinued early due to quality issues related to chunking. The TA51+ is positioned as a direct successor and corrective update rather than a parallel product.

Regions Availability

The Kumho Solus TA51+ is available in South Korea, where it was launched, and is distributed through Kumho's domestic dealer network and online retail channels. It is also listed by retailers in Australia, Azerbaijan, and select European and Canadian outlets. The tire is not officially distributed in the United States under the TA51+ designation; the North American market receives the Solus TA51a, a related but distinct product. Size coverage spans 14- to 19-inch rim diameters, with a treadwear warranty of 40,000 km in some markets.

Vehicle Compatibility / Popular Vehicle Fitments

Given the regions where the Kumho Solus TA51+ is available and the sizes in which it is produced, it is compatible with a wide range of passenger cars and firm-suspension sedans popular in these regions. Some vehicle fitments include:

• Kia K5
• Hyundai Sonata
• Hyundai Avante (Elantra)
• Chevrolet Orlando
• Volvo V60 Cross Country

Note: Always consult with a tire specialist or the vehicle's manufacturer to ensure correct tire fitment.

Final Thoughts

The Solus TA51+ is for drivers who prioritize ride comfort and cabin quietness over maximum dry handling sharpness. In the 2026 AutoView mid-range comfort test, it won outright with the best subjective ride comfort score (8.10), the quietest cabin at 80 km/h (59.3 dBA), and the highest cornering limit of the five tires tested. Testers called it the best choice for firm-suspension cars like the K5 and Sonata.
