Best test result: #5 of 10 in 2018 Auto Express Summer Tyre Test (overall ranking)
“ST feels boaty on new Falken’s I recently purchased a set of 245/40/18 Falken Azenis FK510 to put on my stock wheels. After, the car feels like it’s constantly driving on a wet road. Even after getting heat into the tires, the car feels boaty and like the rear end doesn’t want to follow the front. Any tips? Or did I make a bad choice in tire?”

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
From Reddit, forums and review threads. Not part of our score
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.
“Out of those, the FK510's will be your best all-around considering the rain where you are. They're very grippy and good in the wet.”
“I have Fallen FK510s and live where it rains 300 days a year, they perform great and I'm sure the 520 is even better”
“Do you mean FK510? These are mid range UHP tyres and usually perform near the bottom when tested against other UHP tyres: Poor braking performance and oversteer balance would be my main concerns based on those test results. I wouldn't run FK510s on any of my RWD cars but if cost is your main concern then you do you.”

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.
