Audi A4L comes with original Michelin 245/40-R18 tires and 10-spoke 18-inch V-shaped aluminum alloy rims. The advantages of Michelin tires include comfort, soft tread, and good noise reduction. Below is relevant information about tires: 1. The main functions of tires are dry grip, hydroplaning resistance, providing comfort, reducing driving noise, impact resistance, wet grip, load capacity, handling performance, and average wear. 2. The cross-sectional structure of a tire can generally be divided into four parts: tread, shoulder, sidewall, and bead. Each part has its own function. The tread mainly contacts the ground, the shoulder and sidewall provide support, and the bead contacts the rim to create a seal.

I've been driving an Audi A4L for almost four years, and it came with original 225/50 R17 Michelin or Bridgestone tires. For my model, it was equipped with Michelin Primacy 4 tires, which are quiet, comfortable, and quite durable. The tire size and brand may vary depending on the model year, with higher-end versions possibly featuring sportier Pirelli tires. Tires are crucial for handling and safety—these tires provide good grip on wet roads, reducing the risk of skidding. Climate plays a big role; living in the north with low winter temperatures, I later switched to a set of winter tires for added peace of mind. It's advisable to regularly check tread wear—replace them if the depth is below 3mm. For city driving, choose low-noise tires for comfort, while for highway driving, prioritize stability to avoid fatigue. Original tires typically last about 40,000 to 60,000 kilometers.

As a family user, my A4L's original Goodyear Assurance series tires in size 225/50 R17 provide stable driving and are suitable for daily commuting. Safety comes first - tire condition directly affects braking distance and cornering stability. I check tire pressure monthly to maintain around 2.5. These tires perform well in rainy conditions thanks to their drainage capability from the original design, allowing me to take kids out without worrying about tire issues. When wear became excessive, I switched to Michelin tires which are more fuel-efficient and reduce bumpiness. Before long trips, I always check tread depth to avoid potential hazards. Driving habits like avoiding sudden braking can extend tire life. Proper tire-vehicle matching is crucial - never arbitrarily change sizes to prevent handling issues.

The Dunlop Sport Maxx tires on the A4L Sport model, sized 225/50 R17, offer strong grip and exhilarating acceleration. I love the cool look of wider tires. The factory tires perform well in dry conditions but require more caution on wet surfaces for stable handling. For upgrades, consider brands like Pirelli.
