Last updated 7/03/2024 - Originally published 7/03/2024

Many performance-loving drivers in the US want to go fast from time to time. However, for the speed to be under control, it is important to have a high grip, all of which can be made possible by Ultra-High-Performance (UHP) tires.

UHP-summer tires, as their name suggests, are suitable only at temperatures above 45 degrees Fahrenheit, but they’re still given high regard by buyers owning sports cars, muscle cars, and other high-end performance vehicles.

Here at SimpleTire, we shall be comparing two such tires, namely the Firestone Firehawk Indy 500 and Kumho Ecsta PS91. Between the two, the Ecsta PS91 looks very unique due to a racing-inspired checkered sidewall design. Find out more about them during this Firehawk Indy 500 vs Ecsta PS91 tires comparison.

Firestone Firehawk Indy 500 tires

Designed for use on sedans, compact cars, coupes, muscle cars, and sports cars, the Firestone Firehawk Indy 500 is a UHP-summer tire that has been designed for better handling, improved hydroplaning resistance, and great braking performance. Controllability and handling are pretty impressive for a tire in its category. As compared to its previous generation Firestone Wide Oval Indy 500, this tire stops faster by a significant margin. Do not be confused with the name, as it has nothing to do with the Indy 500 Formula cars. Plenty of technology has been used to make this tire, more of which will be visible as we move ahead. The Firestone Firehawk Indy 500 is good enough for an average SimpleScore of 8.2. Some of the vehicles for which it would be a great fit include the Audi S4, BMW M3, Lexus IS, and Subaru BRZ.

Kumho Ecsta PS91 tires

The Kumho Ecsta PS91 has been designed with supercar owners in mind, offering a higher speed rating than the Firehawk Indy 500. It features a compounded rib tread design that enhances stability at greater speeds. Among other aspects of design, a C-Cut 3D design ensures optimum braking performance and a racing-oriented checkered sidewall design makes the tire appear attractive. Rayon and high-strength steel have been used for extra strength here. Both these tires cannot be used in snow or ice at near-freezing temperatures. Some of the vehicles that will best fit this tire include Dodge Challenger Hellcat, Porsche 911, and Ferrari F430.

Firestone Firehawk Indy 500 vs Kumho Ecsta PS91 tires on traction

A robust tread compound and wider footprint result in good traction for the Firestone Firehawk Indy 500, leading to an average traction SimpleScore of 8.5. The unique tread pattern features a Pulse Groove Channel for quick water evacuation, leading to a lower risk of hydroplaning. The tread depth on the Ecsta PS91 is marginally higher than that of the Firehawk Indy 500.

On the other hand, the Kumho Ecsta PS91 has been designed to provide good traction and grip using a silica compound and carbon black with Max Grip Performance Resins. Four wide circumferential grooves remove water from below the contact patch, thereby enhancing the wet grip. We found the tire suitable for an average traction SimpleScore of 8.5.

Apart from speed, factors such as cornering, handling, and braking are other important aspects of the performance of UHP-summer tires like these. While the Firehawk Indy 500 features a W-speed rating, the Ecsta PS91 is much quicker at Y.
