The Kumho Ecsta PS31 in size 215/45R17 91W is an entry-level Ultra-High Performance (UHP) summer tyre that has become the 2026 value champion for compact sedans and hatchbacks. The (KR) marking confirms it is manufactured in South Korea, ensuring high standards of construction and compound consistency.

In Singapore, this size is a popular fitment for the Toyota 86 / Subaru BRZ, Honda Civic, and the Hyundai Avante/Elantra, where drivers seek a sporty look without the premium cost of Tier-1 brands.
