Differences
1. Dry Performance
I’m going to compare the performance of two summer tires as they are the ideal type in dry weather.
I’m taking a look at the Kumho Ecsta PS91 vs the Sumitomo HTR Z5.
In my assessment as a tire performance reviewer, I would rate the dry performance of the Kumho Ecsta PS91 as 4.6 out of 5.
This tire has received highly positive ratings for its grip, braking ability, handling, and high-speed durability.
Its track-inspired performance and emphasis on traction, control, agility, and durability indicate strong capabilities.
On the other hand, the Sumitomo HTR Z5 scores slightly lower at 4.4 out of 5.
While it excels in dry handling and offers maximum performance in summer conditions, it falls short of a perfect rating.
Considering these ratings, the Kumho Ecsta PS91 appears to have a slight edge in dry performance.
2. Wet Performance
For the wet performance, I’ll be comparing the Kumho Solus TA71 vs the Sumitomo HTR A/S P02.
In my research, I rated the Kumho Solus TA71 tire’s wet performance at 4.1 out of 5.
While it offers somewhat reliable wet traction, there are mixed reviews regarding sudden breakaway in wet conditions.
The tire’s asymmetric tread design and wide grooves contribute to its wet performance, and some users have reported good traction.
On the other hand, the Sumitomo HTR A/S P02 tire received a wet performance rating of 4.4 out of 5.
Its silica-enhanced tread compound and asymmetric tread pattern provide excellent grip and stability on wet roads.
The tire’s design and reported ride comfort add to its wet performance score.
Although wet braking details are limited, the suggestion of its next-generation version outperforming it in wet braking indicates satisfactory wet braking performance.
Based on these findings, the Sumitomo HTR A/S P02 tire has a slight advantage in wet performance.
3. Snow Performance
We all know that you need dedicated winter tires if you’re going to be driving on harsh winter conditions.
That’s why I’ll be comparing the snow performance of two specialized winter tires – Kumho WinterCraft WP71 vs Sumitomo Ice Edge.
As the one giving the snow performance rating from 1 to 5, I would rate the Kumho WinterCraft WP71 tire’s snow performance at 4.4, while the Sumitomo Ice Edge tire receives a rating of 4.5.
Both tires offer reliable snow performance, but the Sumitomo Ice Edge edges slightly ahead with its advanced technology, excellent traction, and studdable option.
Therefore, when considering snow performance alone, the Sumitomo Ice Edge tire emerges as the winner.
4. Mileage Warranty and Tread Life
| Kumho | Sumitomo | |
| Treadwear Warranty | Replacement for unserviceable tires with more than 2/32″ tread remaining | up to 90,000 miles tread life warranty |
| Average Tread Life | Kumho tires are known for their long-lasting performance, with most of their tires lasting from 60,000 to 80,000 miles. | Overall, Sumitomo tires are known to have a relatively high lifespan, with most models lasting between 55,000 to 70,000 miles. |
Based on my research, both Kumho and Sumitomo offer impressive warranties for their tires.
Kumho provides a treadwear warranty that replaces unserviceable tires with over 2/32″ tread remaining.
On the other hand, Sumitomo offers an outstanding tread life warranty of up to 90,000 miles.
