Our take

The Falken Ziex STZ05 is a solid choice for drivers who need a durable all-terrain tire with a focus on longevity. Its treadlife score of 8.8 and 50,000-mile warranty are significant advantages, especially in a segment where durability is key. The wet grip rating of 6.0 also stands out, offering better-than-average performance in wet conditions, which can be a deciding factor for those who frequently encounter rain.

In terms of category priorities, the Ziex STZ05 offers a balanced performance with a focus on treadlife and wet grip. While its dry grip score of 6.5 is slightly below the category average, it remains competitive in most conditions. The tire's UTQG treadwear rating of 660 further emphasizes its durability, making it a reliable option for long-term use.

When compared to competitors like the Yokohama Geolandar A/T G015, which offers a 60,000-mile warranty, the Ziex STZ05 may not be the best choice for those seeking the absolute lowest cost per mile. However, its wet grip performance and overall durability make it a strong contender for those prioritizing these attributes.

If dry grip is your main concern, you might want to explore other options. However, if you need a reliable, long-lasting tire that performs well in wet conditions, the Ziex STZ05 is worth considering.

Pros

  • Treadlife score of 8.8 is above the category average, backed by a 50,000-mile warranty.
  • Wet grip rating of 6.0 exceeds the category average of 5.2, giving it an edge in rainy conditions.
  • UTQG treadwear rating of 660 surpasses the category benchmark of 570, indicating long-lasting durability.

Cons

  • If you prioritize dry grip performance, this tire falls slightly short of the category average.
  • Noise level is average for the segment, matching the category benchmark but not excelling.
  • Dry grip score of 6.5 is slightly below the category average of 6.6, which may affect performance on dry roads.
  • The Yokohama Geolandar A/T G015 offers a higher treadwear warranty of 60,000 miles, potentially reducing long-term costs.
