Our take

The Primacy 4 ST is a solid choice for drivers who value comfort and a quiet ride in the grand touring all-season category. Its comfort and noise scores both meet the category benchmarks, making it a good fit for long-distance cruising. However, the treadwear rating of 340 is significantly below the category average of 574, and the absence of a treadwear warranty means you'll likely face more frequent replacements, raising the overall cost of ownership. In terms of wet grip, the Primacy 4 ST slightly outperforms the category average, which is reassuring for rainy day drives. Handling is on par with the segment, providing balanced everyday performance. However, the R speed rating may not satisfy drivers looking for higher-speed capabilities. When comparing with competitors like the General AltiMAX RT45, which offers a treadwear warranty, the Primacy 4 ST falls short on long-term value. The BFGoodrich Advantage Control and Vredestein Quatrac Pro+ also offer competitive alternatives with potentially better treadwear ratings. If you're a high-mileage driver or need a tire with a warranty, consider alternatives like the General AltiMAX RT45. Choose the Primacy 4 ST if comfort and noise are your top priorities, and you're willing to trade off treadlife for a smoother ride.

Pros

  • Comfort and noise scores of 8 align with the category average, ensuring a quiet and smooth ride typical of grand touring tires.
  • Wet grip score of 7.5 slightly exceeds the category average of 7.4, providing reliable performance in rainy conditions.
  • Handling score of 7.5 matches the category average, offering balanced performance for everyday driving.

Cons

  • The lack of a treadwear warranty and low UTQG treadwear rating suggest a higher cost of ownership due to more frequent replacements.
  • Treadwear rating of 340 is significantly below the category average of 574, indicating a shorter lifespan compared to competitors.
  • No treadwear warranty is offered, unlike the General AltiMAX RT45, which provides a mileage guarantee.
  • Speed rating of R is lower than some competitors, which may limit high-speed performance for certain drivers.
