From Reddit, forums and review threads. Not part of our score
Community members frequently view the Falken Azenis FK510 as an affordable, budget-friendly alternative to premium tires like Michelin Pilot Sports, offering strong wet weather grip and good everyday road comfort. However, opinions are mixed due to rapid treadwear, with multiple drivers reporting bald tires in 10,000 to 15,000 miles or poor durability during track and autocross sessions. Furthermore, some users note compromises in steering response, road noise, and overall performance compared to top-tier max performance tires.
“I put the fk510 on my 2014 535d msport and the rears only lasted 10-11k or one year. Trying something different. They are a good performance summer tire but not worth replacing every year.”
“Falken Azenis FK510 prices? Anyone know why the prices for Falken Azenis FK510's went up 25% or more in the last month? 235/40R18 went from $154 to $192. The whole benefit of these tires is that they offer PS4S performance for way less money. Now, you midaswhale just buy the Michelins. I haven't seen any other summer tires make that kind of a jump in price. I know Falken announced a price increase for 2022, but it was only like 5%. What's the dealio? Read more”
“I've had a set of Falken Azenis FK510's on my car for a couple of months now, and just this past weekend took a trip through the twisties up to Prescott, and pushed the car as hard as I could heading up the mountain. I was a little nervous as I'd never used Falken tires before, but trusted in Tire Rack's reviews of them and pushed the envelope in every turn I hit. It was a pleasant surprise to find that the tires were gripping just as well as the much more expensive Michelin tires they'd replaced, and I even hit a personal best of .95g going around one of the more nasty turns. During this entire drive I never felt once like the tires weren't gripping perfectly, or that I was going to lose control from them breaking loose. Road noise is pretty much non-existent, and they seem to run pretty smooth over every surface I've driven them on so far. All-in-all I don't regret my purchase one bit, and if their longevity is anything like what I got out of my previous set of Michelins I'll definitely be buying another set once this one is done for.”

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.
