Our take

The Westlake SU318 H/T is a budget-friendly option for highway driving, but its 50,000-mile treadwear warranty is notably shorter than the category average of 61,048 miles. This could be a deciding factor for high-mileage drivers. Its wet grip score of 7 is a strong point, outperforming the segment average of 6.1, making it a solid choice for those who frequently drive in rainy conditions.

In terms of handling, the SU318 H/T scores a respectable 7.5, aligning well with other tires in its category. However, its dry grip is slightly below average at 7.5 compared to the category benchmark of 7.7, which might impact performance on dry roads. The tire's comfort and noise levels are on par with the category averages, providing a standard ride quality.

When compared to competitors like the Firestone Destination LE3 and Hankook Dynapro HT RH12, the SU318 H/T offers competitive wet grip but falls short in terms of treadwear warranty and dry grip. For those who prioritize long-term value and dry road performance, these competitors may be more appealing.

Overall, the SU318 H/T is best suited for budget-conscious truck owners who prioritize wet grip and handling but should be avoided by those who need a longer-lasting tire for extensive highway use.
