All 265/40R21 Tires
The Atturo AZ850 is perfect for drivers who want maximum dry grip and handling for performance-focused driving. However, its wet grip score is a significant drawback, making it less suitable for areas with frequent rain.
The ContiSportContact 5P is best suited for drivers who demand top-tier dry and wet grip along with exceptional handling capabilities. However, its moderate comfort and noise levels, along with no treadwear warranty, might deter those seeking a more balanced everyday tire.
The ExtremeContact DWS 06 Plus is a strong choice for drivers prioritizing treadlife and dry performance in a performance all-season tire. However, its comfort and noise levels may not meet the expectations of those seeking a more refined driving experience.
The Alenza AS Ultra is ideal for drivers seeking a comfortable and long-lasting touring tire with an excellent 80,000-mile warranty. However, its 'R' speed rating may not suit those needing higher speed performance.
The Blizzak LM005 RFT is best for SUV drivers who need run-flat capability and are willing to compromise on certified winter performance. The absence of 3PMSF and detailed traction scores may deter those in harsher winter environments.
The Turanza LS100 RFT is well-suited for drivers who value comfort and noise reduction in their daily commute. However, the absence of a treadwear warranty and a lower UTQG rating may result in a shorter lifespan than some competitors, impacting long-term value.
The ContiSportContact 5 SUV is a solid choice for those prioritizing wet and dry grip in an ultra-high performance summer tire, with a commendable treadwear rating of 420. However, its comfort and noise levels might not satisfy drivers who value a quieter, smoother ride.
The CrossContact LX Sport is best for drivers who value comfort and noise reduction in their daily commutes or long trips. The lack of a treadwear warranty and a lower speed rating are its main drawbacks, especially for those who drive at higher speeds or want mileage guarantees.
The Turanza T005 RFT is best for drivers who value comfort and noise reduction, with the added benefit of run-flat capability. However, its low treadwear rating and lack of a warranty mean it's not the best choice for those looking for long-lasting tires.
The Potenza Sport is perfect for drivers who prioritize dry and wet grip along with exceptional handling. However, its lower comfort and noise scores may not suit those looking for a more refined daily driving experience.
The CrossContact UHP suits off-road enthusiasts seeking a balance between off-road capability and on-road handling. However, its higher noise levels and lack of a treadwear warranty might be a dealbreaker for those prioritizing comfort and long-term value.
