300/680/18 tyre Yokohama A005

1. Product introduction

The Yokohama A005 tyre in size 300/680/18 is a slick intended for circuit use, competition or intensive track days. Developed to offer high grip on dry tracks, it is aimed at sports cars, racing cars and prepared vehicles requiring a precise, high-performance tyre fitment.

2. Part function

The slick tyre provides direct contact between vehicle and track. Unlike a grooved road tyre, its smooth tread maximises the contact patch to improve traction, braking, stability under cornering loads and line precision. The Yokohama A005 is designed to operate at high temperatures and offer optimal grip in dry track conditions.

3. Symptoms or consequences of a worn or faulty part

A worn, poorly stored, excessively old or deteriorated slick tyre may significantly reduce performance and safety on circuit.

• Loss of grip during acceleration, braking or cornering
• Less consistent lap times and less precise handling
• Longer braking distances
• Overheating or uneven tread wear
• Increased risk of carcass deterioration during intensive use

4. Benefits of replacement

Replacing a worn tyre with a new Yokohama A005 or one in good condition restores effective, consistent track performance. The choice of soft, medium or hard compound allows the fitment to be adapted to temperature conditions, circuit type, vehicle weight and driving style.

• Optimal grip on dry tracks
• Improved stability in fast corners
• More precise steering response
• Improved traction on corner exit
• Performance adapted through compound choice
