The Yokohama Advan A052 is an extreme performance summer (ultra-high-performance) tyre, positioned as the successor to the Advan A048 R-Spec. It's built on the same production line as Yokohama's dedicated competition tyres, translating race-derived technology into a DOT-legal tyre for drivers who split their time between spirited street driving and track days.
An asymmetric tread pattern is central to the design, with a wide, low-void outer rib that keeps the tyre planted and stable through hard cornering, while a notched outboard micro-groove helps dissipate heat during sustained track use. Two wide circumferential grooves and a notched inner shoulder work together to clear water from the contact patch, giving the A052 wet-weather traction that's a step above what you'd expect from a tyre this focused on outright grip.
Underneath the tread sits Yokohama's motorsport-derived MS compound, tuned to deliver extreme levels of both wet and dry grip while incorporating BluEarth technology for improved rolling efficiency compared to a pure race compound. The casing pairs two plies of nylon cord with two wide steel belts, plus two spirally-wound nylon reinforcement plies, producing a structure built for precise, high-speed steering response and consistent handling as loads build through a corner.
Because it's engineered around outright grip, the A052 suits sports cars, tuned performance builds, and dedicated track-day or motorsport applications (vehicles such as the Porsche 911, BMW M3, and Subaru WRX STI are common fits). Like all extreme performance summer tyres, it is intended for warm, dry-to-wet conditions and should not be driven, stored, or fitted in near-freezing temperatures, on snow, or on ice.
Features
- Asymmetric tread design - wide, low-void outer rib delivers powerful, uninterrupted cornering grip.
- Notched outboard micro-groove - improves heat dissipation for consistent performance during sustained track sessions.
- MS motorsport compound - high-silica, heat-resistant formula developed from Yokohama's racing technology for extreme wet and dry grip.
- BluEarth technology - improves rolling efficiency without compromising the tyre's grip levels.
- Two wide circumferential grooves - improve water evacuation and hydroplaning resistance.
- Reinforced casing - two nylon-cord casing plies, two wide steel belts, and two spirally-wound nylon reinforcement plies for precise, high-speed handling.
- Race-derived heritage - successor to the Advan A048 R-Spec, produced on the same line as Yokohama's competition tyres.
