YOKOHAMA TYRES AD09 2254019 225/40r19 225-40-19 ADVAN SEMI SLICK

The Yokohama ADVAN Neova AD09 225/40R19 93W is a road-legal extreme-performance tyre developed for sports cars and modified performance vehicles used on both the street and racetrack.

Also searched as 225-40-19, 2254019 and 225/40 R19, the AD09 is commonly described as a road-legal semi-slick because it bridges the gap between a performance street tyre and a competition-focused track tyre.

Its asymmetric tread pattern features wide, rigid shoulder blocks that support strong lateral grip, precise steering response and confident handling during high-performance cornering.

Wide, wave-shaped grooves efficiently evacuate water from the contact area, helping improve resistance to aquaplaning. The specialised performance compound provides excellent dry-road grip while retaining practical wet-road performance.

A slightly rounded tread profile produces high pattern rigidity and strong cornering force. This helps the tyre deliver predictable handling on winding roads, during performance driving and at track-day events.

Yokohama confirms the AD09 is designed for circuit and everyday street use, with the exact size carrying a 225/40R19 93W specification.

The AD09 is road legal but is not a competition-only slick. Drivers should reduce speed appropriately during heavy rain and cold conditions.
