Now, let’s dive deeper and see what the Kumho Ecsta PS31 is made of.  

Kumho Ecsta PS31 Overview

Kumho Ecsta PS31 is one of the tire manufacturer’s extreme performance summer tire options. The Ecsta PS31 was developed for sports cars, performance sedans, and enthusiast drivers who plan to drive in high-performance driving schools, autocross, or racetracks. 

The PS31 puts ride quality, comfort, smooth handling, high-speed durability, and traction for warmer weather performance into one high-performing tire. 

In its class, the Kumho Ecsta PS31 is an averagely-priced extreme performance tire compared to its competitors such as BFGoodrich and Michelin.

The Kumho Ecsta PS31 is designed with an ultra-high grip tread compound. It has fine carbon black and synthetic resins to enhance traction and stability in high-performance environments. The tire is backed by a 6-Year warranty, which is impressive for its class.   

Performance Breakdown

Now let’s jump into a more comprehensive look at the Kumho Ecsta PS31 high-performance summer tire.  



According to TireRack.com, the Kumho Ecsta PS31 performed impressively in wet conditions, especially for a summer tire, scoring highly in wet traction as well as hydroplaning resistance. 

The Ecsta PS31 is a high-tech tire, designed with dispersible micro-silica which distributes an even layer of silica across the traction area. The PS31’s high grip resin enhances both dry and wet traction. 

The optimized lateral groove angles increase water displacement in turns, and the four wide, circumferential main grooves use diagonal-sipe microgrooves to pass water from the traction points under the tire for maximum grip in wet weather. 


This is where the tire shines. The Kumho Ecsta PS31 tested well in cornering stability, steering response, and especially dry traction. 

The high-dispersible micro silica / high grip resin enhances dry traction and is molded into a directional tread pattern including a solid center rib for maximum high-speed stability. There are also 3D dimple-designed heat dimples to minimize heat buildup in the tread blocks and increase durability for reduced wear on dry roads. 

Users reported that the tires were trustworthy in cornering as well as fast straightaways.   


According to customer reviews, these tires feel solid in turns and at high speeds on straight roads, whether dry or wet. Many users reviewed that the tire’s handling was excellent.

Kumho Ecsta PS31’s construction was designed to hold sturdily in turns and provide trustworthy handling for your driving experience. 

The PS31 has a computer-simulated design for consistent contact pressure. It is reinforced internally with a two-ply polyester casing beneath twin wide, steel belts and two full layer nylon cap plies for improved impact resistance and high-speed handling.

Noise and comfort


The tire’s construction includes nothing to minimize noise and is tested averagely in road feedback, though the point of the tire being performance means that this wasn’t a huge point when Kumho was designing them.

Customer reviews claimed that the Kumho Ecsta PS31’s noise levels were quite good. 


The Kumho Ecsta PS31 tested well in ride quality for a performance tire. 

Customer reviews reported that the tires drive smoothly and are a very comfortable ride overall. 


Kumho invested in the lifespan of the Ecsta PS31 with a directional tread pattern with a solid center rib. Its 3D Dimple Design heat dimples decrease heat buildup in the tread block, increasing durability and reducing the tire’s treadwear. 

The tire’s computer-simulated structure increases consistency in contact pressure for even wearing. The reinforced internal construction includes a two-ply polyester casing beneath twin wide, steel belts and two full layer nylon cap plies for increased impact resistance and durability.

The Ecsta PS31’s lifespan is backed up with a 6-year limited treadwear warranty.


For its price-quality to durability index, the Ecsta PS31 feels right on point. Since the nature of max-performance summer tires is not necessarily geared towards longevity, it seems that this tire is accurately priced.

According to reviews by users, the Ecsta PS31 felt accurately priced.
