Best test result: #1 of 7 in 2025 Tire Rack Extreme Performance Track Tyre Test (subj. dry handling)
“Staggered BBSs Need Tires I have a set of BBS wheels that i have been restoring for my 89 944 NA. I am trying to figure out what tires to get and am running into a bit of trouble. The set of BBSs are 15in staggered. The front are 8in wide and the rear are 9in wide. When i had purchased these wheels they had 215/60R15s all around. Would this be a good fitment? I am hoping the rear will not look stretched. As i was researching staggered tires i ran into problems finding a matching set in the sizes 225 50R15 and 205 55R15. A local shop helped me find these for the front Yokohama ADVAN Fleva V701 (205 55R15) and these for the rear Yokohama ADVAN A052 (225 50R15). Im concerned to get these due to the tread pattern being drastically different. Another shop has Kumho Ecsta 4x KU22 picked out for the front. I would like to have performance summer tires that do not break the bank. If i were to do 215/60R15s all around i was looking at Falken Sincera SN250 A/S (which are not performance) or Vredestein Sprint Classic which i am not sure of. I am a bit at a loss here and would greatly appreciate any advice or help selecting tires as this is not something i am comfortable with given the lack of options at this wheel size.”

ADVAN A052
Pros, cons & observations
Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
Tire A Proxes RA1
Pros
- Exceptional dry grip that remains consistent even as the tread wears down.
- Superior tire life compared to many other dedicated track-focused compounds.
- Predictable breakaway characteristics that provide driver confidence at the limit.
Cons
- Performance can become 'greasy' if the tire is overdriven or overheated during long sessions.
- Requires proper heat cycling and break-in procedures to achieve optimal performance.
- Sensitive to alignment settings, which can lead to accelerated or uneven wear if not managed.
Tire B ADVAN A052
Pros
- Class-leading dry grip and traction, often compared to dedicated racing slicks.
- Rapid warm-up time, providing peak performance almost immediately.
- Surprisingly high levels of wet-weather traction and hydroplaning resistance for a performance tire.
Cons
- Rapid tread wear, especially when used on heavy vehicles or without aggressive camber settings.
- Tendency to 'grease up' or lose performance during long, high-intensity track sessions.
- Soft sidewall construction can lead to vague steering feel or 'sponginess' compared to stiffer competitors.

Tire B
Positive
Yokohama ADVAN A052
Community members widely view the Yokohama ADVAN A052 as a top-tier, high-grip competition tire suited for autocross and track driving. While praised for its light weight and superior all-out performance compared to standard street and summer tires, users frequently discuss its high cost, soft compound, potential lack of tread longevity on long road trips, and tendency to fling rocks.

“Long trip with Advans A052? I'm planning a trip to the Nürburgring to attend a trackday this October. The problem is that I live 1300 km away, so the tyres should be able to cope with that, some 20 laps at medium-fast pace at the Nordschleife, and the drive back home. Are the Advan A052 tyres way to soft for such a long trip? Will they last? Wouldn't it be wiser to settle for a more conservative set of Michelins PS4? The car is a 1986 Porsche 911 Carrera, 1210 kg... Read more”

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.
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.
