From Reddit, forums and review threads. Not part of our score
The Firestone Firehawk Indy 500 is overwhelmingly praised as an exceptional value and 'bang for your buck' summer performance tire. Drivers consistently highlight strong dry grip, commendable wet traction, comfortable ride quality, and progressive handling breakaway. Minor criticisms center on reduced performance in cold temperatures, softer steering feedback, and grease on hard track sessions.
“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.”

“I need a 224/45/15 I run these on my S2000 wheelset for driving around town and they are great. I also have used them for plenty of track days. They get a little greasy towards the end of sessions but have never let me down.”

Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.
Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
