“Upgrading tires from Falken Azenis FK510, looking for recommendations Hey all, I drive a V6 1LE camaro, i've been doing a lot of open practice sessions at a small track (the driveway in austin, tx), long story short I bought brand new Azenis FK510 two months ago, only about 4k street miles, and after about 3 hours of track time they're pretty much done....mostly from noob mistakes like overcooking the entry and destroying the front shoulders, and having the rear tires way too overinflated so the shoulders are fine but the center are down to the wear bars. Even under ideal conditions and purposely driving slower and smoother I can't see these lasting much more than 4-5 hours of track time, I'm just surprised to see these tires wear down very very quickly under hard driving and overheat somewhat quickly, these are awesome daily driving tires but I'm looking for more track performance. I'm currently debating between pilot sport 4s, bridgestone re-71r, firehawk indy 500. This is more of a philosophical question, I'm looking at a wide variety of treadwear tires, I'm curious how you guys decide on what treadwear tires to run and how you decide between wear, price, and grip. I'm leaning towards the RE-71r right now, I figure if I'm burning through my tires in a few months anyways might as well do it with sticky tires since my falkens didn't last long anyways...

Tire A

Falken Azenis FK510

Mixed

Community opinions on the Falken Azenis FK510 are generally mixed, balancing praise for their value pricing and strong wet-weather grip against complaints regarding soft sidewalls, rapid tread wear on heavy or track-driven vehicles, and handling that some drivers describe as "boaty." While many view them as a cost-effective alternative to premium tires like the Michelin Pilot Sport 4S, others note that recent price hikes and mixed performance in testing make them a secondary choice compared to dedicated track or alternative ultra-high-performance tires.

How do we compare tires?

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.

Community buzz from Reddit and forums is shown for context only — it never changes the score.
