Avon Zv7 vs Michelin Pilot Sport 4

Both are ultra-high-performance summer tires that perform well in hot weather on both wet and dry roads. The Sport 4 is more concerned with wet grip because it has larger grooves that can easily outperform any tire in wet circumstances, whereas the Zv7 is more focused on improving its dry grip. Because of its better shoulders, the Zv7 surpasses the Sport 4 in both dry and wet handling.

The Sport 4 tire has a higher void ratio which allows lower rolling resistance, resulting in a significantly more fuel-efficient tire.

Comparing Michelin PS4 with Avon ZV7

Michelin Pilot Sport 4

Vs

Avon Zv7

Zv7 features an asymmetrical tread pattern with densely packed tread block columns, which improves the contact area of the tire and so gives a larger contact patch to the tire to engage with the road which improves tire traction. The shoulders of this tire are designed to provide maximum road contact, resulting in a perfect tire. The tire’s shoulders, on the other hand, have deeper sipes, allowing it to outperform its competitor in wet circumstances. As the contact patch gets bigger, the rolling resistance of the tire also increases and reduces the tire’s fuel efficiency. It is quieter on the road, although it is less comfortable on wet roads.

Michelin Pilot Sport 4

Because of its wider grooves, the Sport 4 has an asymmetrical tread pattern with a greater void ratio. The tire’s grip is reduced due to wider grooves, and the dry braking distance is increased.   However, on wet roads, it is the most efficient tire because it has larger grooves and numerous thin sipes that effectively sweep the water away from the tread, making it one of the best choices. As a result, the tire’s resistance to hydroplaning is excellent. Unfortunately, the shoulders of the tire aren’t wide enough to provide a solid contact patch, and it lacks efficient siping, making it tough to handle in both dry and wet situations.

Road Grip Comparison

The Zv7 is generally preferable on-road in dry conditions because of its small grooves, which allow a large segment of the tread area to come in contact with the ground. Its dry grip is improved, and the dry braking distance is reduced to only 111 feet. This tire falls short in terms of traction on wet roads because it has insufficient grooves to effectively wipe away water and prevent the tire from sliding. It has a 118.5 feet wet braking distance, which is significantly more than its competitor.

The dry grip on the road of Sport 4 is less due to its higher void ratio. The tire’s grip is decreased due to its small contact area, leading to a greater dry braking distance. It has a dry braking distance of 112 feet. On the other side, it has larger grooves and numerous narrow sipes that enable water to pass through the tread and reduce wet braking distance. The tire has a 115 feet wet braking distance, making it ideal for wet grip.

Handling Comparison of the tires

The Zv7 has a better contact patch and improved handling because of its broad shoulders and deeper sipes.  Its higher shoulder contact patch is responsible for its better dry handling, while its deeper shoulder sipes are responsible for its sharp wet handling.  It accomplishes a lap around over a circular path in 95 seconds in dry conditions and 62 seconds in wet conditions. The handling competition is won by this tire because it has a lower dry and wet lapping duration.

Sport 4 tire has concise shoulders, broader grooves, and multiple sipes, lowering the contact patch with the road and reducing dry handling capacity. As a result, a significant amount of speed will be lost while steering, extending the time it takes for a vehicle to accomplish a lap. This tire takes 97 seconds to complete a lap around a circular track, placing it second in dry handling. The tire loses its competition in wet circumstances as well, as it accomplishes a lap around a circular path in 64 seconds.

Comparison of Hydroplaning resistance

In terms of aquaplaning resistance, the Zv7 cannot compete with its competitor. In severe rainy weather, this tire is vulnerable to hydroplaning, gradually losing control and skidding. It seems to have a lesser floating speed of 43.8 mph, which makes it less suitable for rainy weather.

Sport 4 has a great aquaplaning resistance because of its wider grooves, which are much more proficient at passing water from them, this results in a tire that is extremely aquaplaning resistant. Its floating speed is substantially higher than that of other tires which is 49.4 mph.

Comparison of Rolling Resistance

The amount of force required to keep the tire rolling is known as rolling resistance. The contact patch of a Zv7 tire is larger, and a larger contact patch means more frictional force is required to overcome it. It offers a higher rolling resistance, as a result, its fuel efficiency is reduced. Due to having a smaller contact area, Sport 4 has a lower rolling resistance and so as a result, less force is required to move it, leading to a tire that uses less fuel.

Comfort and Noise Comparison         

The Zv7 is significantly quieter on the road because of its narrow grooves, which provide limited space for air particles to become stuck in the tread and cause noise.  It has better dry comfort due to its better stability and steering control on dry roads, it lacks wet comfort due to its narrow grooves which useless on wet roads, putting the driver at risk of hydroplaning.

The Sport 4 has a substantially higher noise comfort rating because of its wider grooves, which allows a larger number of air particles to become lodged inside grooves, impacting the walls and causing the noise. Moreover, because of its wider grooves and more sipes, its wet comfort is significantly higher, and its dry comfort would be significantly lower, due to its lower effectiveness and control on dry roads.

Durability and Treadwear Differences

The Zv7 tire has a larger contact patch which increases rolling resistance and leads to increased treadwear. This tire is durable due to its unique tread compound and stiff sidewalls. The treadwear resistance of this tire is reduced as a result of increased contact patch, making it less durable and reducing its mileage.

Sport 4 features a larger void ratio, which reduces the contact patch and the rolling resistance. The tire’s treadwear is reduced as a result of the lower rolling resistance. It is composed up of a highly refined silica-based tread compound that provides increased tread wear resistance and, as a result, a tire that is far more durable. Because of its increased durability and lower tread wear, the tire’s mileage is also increased.

Price Differences

Zv7 is a much more costly tire due to its ultimate wet handling and dry traction. It has a soft rubber material compound, which enhances its efficiency, and it has a drawback that it wears out faster. Sport 4 is a slightly cheaper tire with tougher rubber material that offers greater durability and mileage. 

Quick Summary

  • Both are ultra-high-performance summer tires.
  • The wet and dry handling of Zv7 tire is enhanced due to its optimized shoulders.
  • Sport 4 has the best hydroplaning resistance.
  • Sport 4 has less rolling resistance, making the tire more durable and allowing for more mileage.
  • Sport 4 has more dry braking distance than Zv7.
  • The treadwear resistance of Zv7 is less as compared to sport 4.
