Are you in search of summer tires that excel in every aspect of performance? Well, we have just the right tires for you. The Avon ZV7 and the Uniroyal Rainsport tires are both mid-range summer tires that are built to provide top-notch performance to their users. Here We would be looking at Avon Zv7 and the two variants of Uniroyal Rainsport (5 and 3).
Starting with 5…
The ZV7 offers better traction on dry roads due to its higher contact patch whereas the same size of the Rainsport 5 provides better hydroplaning resistance due to its wider grooves.
Comparing Uniroyal RainSport 5 with Avon ZV7
Featuring an asymmetrical tread design and relatively narrower grooves, the Avon ZV7 is the clearly winner of dry traction here. The narrower grooves of the tire make its contact patch higher, and as a result, the users get an excellent grip on the dry surfaces. Moreover, the tire’s optimized shoulders also boost its handling on dry roads. However, due to the narrower grooves, the hydroplaning resistance of this tire is not as effective as that of the Rainsport 5. Not only this, but the rolling resistance also becomes higher as well since its contact patch is higher. Due to the higher rolling resistance, the tires’ fuel efficiency decreases, and the mileage also gets lower. But, on the brighter side, their price is extremely affordable. This is what makes the ZV7 one of the favorite options of the users.
In comparison, the Uniroyal Rainsport 5 features a higher void ratio, decreasing its contact patch, making it lower comparatively. So, its dry traction is not as effective as that of ZV7. However, the tire’s hydroplaning resistance is excellent due to its wider grooves which allow effective evacuation of water. Due to the lower contact patch, its rolling resistance is lower as well. This increases its fuel efficiency and mileage.
One of the fundamental jobs of a tire is to maintain a firm grip on the road, providing a balanced and steady ride with safety. The Avon ZV7 possesses narrower grooves as compared to the Uniroyal Rainsport 5. As a result, its higher contact patch engages well with the surface of the road. Thus, the grip of the tire gets stronger, resulting in better dry traction. Talking about the wet grip, the sipes play a major role besides the contact patch of the tire. As far as the ZV7 is concerned, there are numerous sipes present on the outer tread of the tire which enhances these tires’ grip on wet surfaces by allowing them to wipe away the water.
When it comes to the Uniroyal Rainsport 5, the contact patch of this tire is lower as compared to its competitor. That’s because it possesses relatively wider grooves, allowing a lower contact patch which results in a higher braking distance. Other than that, the number of sipes on the central part of the tire is also lesser in comparison. They are not as efficient in evacuating the water as ZV7’s sipes. As a result, the grip of these tires on both dry and wet roads is compromised.
Talking about the handling capability, the ZV7 offers a remarkable handling performance due to its incredible shoulder design. Since there are narrower grooves on its shoulders, it leads to a higher contact patch of the shoulder. As a result, the drivers get excellent steering control on dry roads. The same is the case for wet handling. The power sipes found on the shoulders of the tire along with a higher contact patch increase its wet handling.
On the other hand, the Rainsport 5 consists of wider grooves on its shoulders. The position of its blocks is unable to maintain traction effectively. This is what makes its contact patch lesser as compared to its counterpart’s shoulders. Since this tire has a lower shoulder contact patch, it’s handling on dry roads is compromised to some extent. When it comes to wet surface handling, it is also relatively lower due to the lesser number of sipes on its shoulders. So, in short, the overall traction of the Avon ZV7 is much better as compared to that of Rainsport 5.
Comparison of Hydroplaning Resistance
The hydroplaning resistance is one of the factors which makes a major difference between the two tires. After researching thoroughly, we concluded that the ZV7’s users will face more issues of hydroplaning as compared to the Rainsport 5 users. Because the narrower grooves of the Avon ZV7 are inefficient at channeling away the water effectively. Thus, it can be extremely dangerous to drive this tire at high speeds in the rainy season.
Whereas, when we look at the Rainsport 5, it can be noticed that its grooves are much wider in comparison. In addition to this, there are 3D patterns on its tread blocks to push away the water from the tread. This helps in maintaining the contact between the tire and the road, even in extreme wet conditions.
Comparison of Rolling Resistance
The energy that is required to roll a tire over the road is known as rolling resistance. ZV7 has a higher contact patch for better traction, they don’t do much for rolling resistance because a higher contact area increases its rolling resistance. As a result, the vehicle’s fuel consumption increases since a larger amount of energy will be required to rotate the tire.
In comparison, due to the lower contact patch of the Rainsport 5, its rolling resistance is much lower. This leads to higher fuel efficiency as well.
Durability & Treadwear
Coming to durability and treadwear, the Avon ZV7 is more prone to wear and tear due to its weaker built. Since the durability of these tires is lower than their competitor, they will also offer less mileage. However, there are certain built-in protective features in this tire such as rim protector and thickened sidewalls that prolong the life of its tread. Not only this, but these features will also help the tire against scratches.
On the other hand, the Rainsport 5 has a longer tread life as compared to the ZV7. That’s because of the lesser contact area, decreasing its rolling resistance. In addition to this, they are manufactured using carbon black tread and special silica compounds. This adds more to their durability even on road with rough conditions and high temperatures. Due to the RUN FLAT tires used by the manufacturers, these tires become an extremely safe option to use as they can provide the users with great control. Not only this, but it also allows the drivers to drive safely even during the rapid loss of inflation pressure.
The Avon ZV7 and the Uniroyal Rainsport 5 are both some of the best mid-range summer tires available out there. However, the Rainsport 5 costs a bit more than its competitor due to its better hydroplaning resistance. In addition to this, the lower rolling resistance makes them fuel-efficient and a more durable option too. But, if you are looking for a tire that offers better traction, then the Avon ZV7 with its affordable price is the best option to consider.

Comparing Uniroyal RainSport 3 with Avon ZV7
Zv7 features an asymmetrical design of tread with a tread block column and two ribs sandwiching between its shoulders. The tire consists of four large longitudinal grooves. It does not possess any lateral grooves. A greater number of sipes are present in comparison to its counterpart. 3D sipes are present in it along with comparatively wider longitudinal grooves. The deeper grooves are present on its shoulders that increases its shoulder pitch length. The tread blocks are arranged in a specified order.
RainSport 3 also consists of tread blocks with an asymmetrical pattern. The tire comprises two longitudinal grooves with a tread block column in between. The tread column consists of inclined sipes with relatively more depth. In this tire, extended lateral grooves are also present which gives it an upper hand over its rival in terms of aquaplaning resistance. The lateral grooves are inclined at a particular angle. The bolder shoulders are extended and are connected to the tread. It is made up of hard rubber that is inflexible
Road Grip Comparison
Zv7 consists of a high void ratio which ultimately leads to a lower contact patch. The dry braking distance of the tire is 36.93 meters that’s marginally greater than its competitor. This makes the tire grip a little lower than its peer during dry conditions. However, in wet conditions due to the presence of more sipes, its wet braking distance is much lower than its rival. The wet braking distance of this tire is 36.13 meters, making it more superior to its counterpart in terms of wet grip.
In the case of RainSport 3, due to a much higher contact patch in comparison, its dry braking distance is lower, providing a more optimized dry grip. The dry braking distance of the tire is 35.7 meters, which is slightly lower than its rival. But for wet gripping, its performance falls short of expectation when compared to its counterpart. The wet braking distance of the tire is 50.6 meters which is very high, therefore, causing less grip in a flooded road.
Handling Comparison of the tires
When the performance of the tire is considered in terms of handling, its shoulder design is discussed. Comparatively wider lateral grooves are present on the shoulders of Zv7 which leads to a low dry handling speed. The average handling speed of the tire is 111.4 km/h, marginally lower than its rival. In damp conditions, more sipes on the shoulders help it to perform well leading it to have an average wet handling speed of 74.5 km/h, higher than its rival.
The average dry handling speed of RainSport 3 is 113.7 km/h due to the presence of narrow lateral grooves on the shoulders in comparison to its counterpart. But fewer sipes lead to slightly less performance in wet and rainy conditions as the tire provides an average wet handling speed of merely 67.7 km/h.
Comparison of Hydroplaning Resistance
Despite having wider grooves, Zv7 has a low hydroplaning resistance. Although it contains more sipes, these sipes are shallower causing less water to pass out from the grooves. The floating speed of the tire is, therefore, on the lower side in comparison and lies at 87.3 Km/H.
The hydroplaning resistance of RainSport 3 is on the higher side despite having narrow grooves and a high contact patch. The sipes and grooves present are deeper, allowing more water to move out of the tread, therefore, having more aquaplaning resistance than its competitor. The floating speed of the tire is 95.3 Km/H, much higher than its rival.
Comparison of Rolling Resistance
It is a force required by the tire to keep it moving in the forward direction. The higher the tire makes contact with the ground; the higher will be its rolling resistance and vice versa. Since Zv7 has a minimal contact patch as compared to its counterpart, it causes low friction with the surface, therefore, leading to low rolling resistance. Because of its low rolling resistance, the tire consumes less fuel, making it more fuel-efficient than its competitor.
RainSport 3 makes more contact with the ground because of its slightly narrow grooves, therefore, it results in higher friction between road and tire. The higher friction causes the tire to apply more force resulting in higher rolling resistance. More rolling resistance as a consequence, causes more consumption of fuel making it less economical in terms of fuel efficiency.
Comfort and Noise Comparison
With the marginally wider grooves in Zv7 than its rival, it causes more molecules of air to get captured inside the grooves. More molecules will produce more sound by continuously striking the wall of the tread blocks. This causes it to generate more sound when moving at a high speed. It produces a sound of 73.4 dB that is slightly higher than its peer.
RainSport 3 possesses a faintly lower void ratio, inviting fewer particles of air to get trapped. As a result, fewer particles will move in the back-and-forth direction generating less noise. The noise level of the tire is slightly lower than its peer. It generates a sound of 71.8 dB, making it more favorable for high-speed rides.
Durability and Treadwear Differences
Zv7 despite having a low rolling resistance and low wearing of tread; is less durable than its counterpart. This is due to its slightly low-quality built strength compared to its rival, causing a decrease in its durability thus leading to low mileage.
On the other hand, RainSport 3 despite having a higher contact patch leading to higher rolling resistance and wearing of tread, is more durable than its peer. This is because of its better-built strength and higher quality. This optimized durability leads to better mileage, therefore, prolonging the lifespan of this tire.
RainSport 3 is a highly-priced tire because of its overall decent performance. The tire has also better-built strength and provides more mileage than its rival. Zv7 despite having low durability provides an exceptional wet grip and handling making it one of the most preferred and cheaper tires among its all-other competitors.
