245/40/17 tyre Yokohama A052

1. Product introduction

The Yokohama A052 in size 245/40/17 is a road-approved semi-slick tyre designed for drivers seeking very high dry grip while retaining the option of public road use. Drawing on Yokohama’s competition experience, this tyre is aimed at sports cars, track cars and trackday-focused builds.

2. Part function

The tyre provides the direct link between vehicle and road. It transmits engine power, braking and lateral cornering forces. On a Renault Sport sports car, Alpine or any prepared vehicle, a high-performance semi-slick allows the chassis, running gear and brakes to be exploited more effectively, particularly during dynamic driving or on circuit.

3. Symptoms or consequences of a worn or faulty tyre

• Loss of grip under acceleration, braking or cornering loads.
• Longer braking distances.
• Imprecise handling at the front or rear of the vehicle.
• Increased aquaplaning risk if the tread is excessively worn.
• Uneven wear that may reveal an alignment, pressure or suspension fault.
• Reduced circuit performance and loss of consistency over successive laps.

4. Benefits of replacement

• Significant dry grip improvement compared with a conventional road tyre.
• More precise steering and more direct steering-wheel feedback.
• Optimised traction for powerful or prepared sports vehicles.
• More effective braking thanks to a high-performance contact patch.
• Road-approved tyre suited to mixed sporting road driving and circuit outings.
• Excellent choice to improve performance without switching to a slick lacking road approval.
