Firestone Firehawk Indy 500 vs Kumho Ecsta PS91 — Compared (September 2026)

“Firestone Firehawk Indy 500 Tire Review After my stock rubber wore down I decided to look into other (cheaper) options for this summer. I landed on getting a set of Firestone Firehawk Indy 500 205/40/17 tires and have been on them for about a week now in both rain and dry. The TLDR of this would be buy these tires! The longer version of it is that these tires to me at least feel much more comfortable than the stock tires both in terms of ride comfort and road noise. On top of that the grip in the wet is impressive to say the least! I got a lot of rain here in Oregon so wet performance was really important to me. On the stock tires I always left my TC on and was careful going around turns especially as the tires wore down further and further. These Indy 500 just keep on gripping in the wet and I haven't had any problems at all. The first day I had them out in the dry I would have sworn my car was actually faster accelerating! Probably because there was less wheel hopping or it simply just grabbed the road better. I haven't tried a launch on them yet but hope to do some auto-crossing and such in the Spring. If you have any questions about these things fire away. Read more”

“Firehawk Indy 500s As promised, some initial thoughts. These are extremely comfortable. They honestly made it hard to understand how fast I was going because I've come to gauge my speed based on how much I'm being jostled around. I felt almost nothing with these, and there's so much construction on my way to work from the tire place, including a road that hasn't been surfaced properly yet. Perfect testing run for comfort. In terms of performance these bite the road a lot better and it's a lot easier for me to get moving again. Granted, my run flats were almost bald and that's my most recent memory of how they performed, but it's shocking how much I can take a turn or even just accelerate without any risk of sliding or slipping. It feels like a completely different car honestly, and people aren't kidding when they say "just get better tires" on some of these posts asking about mods. It's not as sexy as a new intake, but it makes a much bigger difference. I mean I feel like I was missing out on at least half of my roadster's potential here. So yeah I definitely like them. I don't mean to insult the tire guys' ability to apply tire shine, but I need to redo that disaster when I'm home. I only have detailing spray right now.”

“Will I regret buying Firestone Firehawk Indy 500s? I have a stock '21 GT Premium convertible with the black appearance package. It came with the upgraded Pirelli P Zero 255/40-19 tires, but with 35,000 miles, they are really worn, and I need new tires. I live in North Florida. We don't have a lot of cold weather (I missed the snow last month), but I do get a lot of rain. I don't track the car, and mostly drive on country roads and the interstate. The Pirelli's have treated me well as far as traction, dry and wet. I like the aggressive look of the Firehawks, but I am concerned about wet weather traction. Will the Firehawks be at least comparable to the Pirelli's for wet weather and general handling? If not, it sounds like the Michelin Pilot Sport A/S 4 is the way to go. Also, the car is all black, with black rims, and the tires look wimpy. I'm not up for new rims this go-round, and I won't lower it because I like the clearance for potholes, etc., that I see a lot of in my area. I'm hoping the tires will help the look a little bit.

“Firestone Firehawk Indy 500 reviews Hi all! First post here on Reddit for S2K. I have a 2002 with 80k (130 km's) that is 100% stock. I recently purchased some new tires moving from a Potenza RE-71 (rear) Potenza RE760 (front) I bought the Indy 500 Firehawk since a lot of S2K owners say they are an excellent tire, perfect for the S2K with a ton of great qualities. So far I am thinking a little bit of a mixxed bag. The tires are not as responsive as I thought and don't inspire the same level of cornering confidence. The seem a little mushy/soft and my rear end thus far doesn't seem as firmly planted as I would like. Almost kind of wobbly? Alignment is fine, tires are brand new with less than 100 miles on them and tire pressure is factory spec within 1 psi. The DOT code for the tires is late 2024 so brand new. I don't track the car and these days just baby it around town mostly so the tires use should fine for my use. Thanks! Leer más”

“Follow up on new wheels/tires for ZHP Well new wheels and tires are on aswell as aligned. I love the tire and fitment setup but really do not like the gunmetal grey color especially on imola. I will feel it out for a while but probably eventually powder coat to OEM silver. Wheels specs are 18 x 8.5 x ET50 with 255/35/18 Kuhmo Ecsta PS91 all around. -2.5 camber in the front and -2.8 in the rear.”

“New meaty tires set up installed, now I can order spacers Went up tire sizes and they definitely fill the gap a bit. First time running sticky kumhos on anytime so excited to see how they turn out.Specs are Kumho Ecsta Ps91 235/40/18 up front and 265/40/18 in the rear. Read more”

“New wheels and tires for my ZHP My old wheels were super beat up and tires were showing wire so I figured I’d upgrade both. Was able to get these freshly powder coated squared set (18/8.5/et 50). Im excited to feel the Kuhmo Ecsta PS91 as they are a budget friendly performance tire. 255/35/18 tires all around”

“275/40 Square Can Fit on a Sedan Shout out to TireRack for having great information on actual tire size. Ecsta PS91 265/40 and ExtremeContact 275/40 has a tread width and section width difference of 0.1” and 0.2” respectively. Tires fit just about perfect. No rubbing so far, and don’t expect it to rub bc of the relatively minimal width change Really goes to show that tire brand matters for fitment Read more”
