All 285/45R21 Tires
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 CrossContact LX Sport SSR is best for drivers who value comfort and noise reduction in a touring all-season tire. The absence of a treadwear warranty is a significant drawback, especially for those concerned about long-term costs.
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 PremiumContact 6 SSR is best for drivers who value comfort and noise reduction on their daily drives. However, its low treadwear rating and absence of a mileage warranty mean it may not be the most economical choice for those concerned with longevity.
The Alenza Sport A/S RFT is suitable for drivers who value comfort and noise reduction, with the added benefit of run-flat technology. However, its lower treadwear rating compared to the category average may lead to more frequent replacements, which could be a concern for budget-conscious buyers.
