CrimeaPRESS reports:
Comparative tests are carried out to determine the differences in braking performance between summer, winter and all-season tyres.
The relationship between temperature and tire performance, especially in wet conditions, is complex and compelling. Wet braking, a critical aspect of driving safety, can vary significantly depending on tire type and temperature ranges. Let’s dive into the data to understand these differences and make an informed decision.
Before diving into the numbers, it’s important to understand the metrics. Wet braking performance is presented as a percentage, with a higher percentage indicating a shorter braking distance. A summer tire serves as a baseline and has a value of 100%, making it easier to compare how other types of rubber perform in comparison to it at different temperatures.
The optimal point for changing summer tires to winter ones
One of the standout findings from the data is the optimal transition point from summer to winter wheels for wet braking. At 8.7°C there is a noticeable shift in performance. Although summer tires can provide acceptable braking at higher temperatures, as they approach this transition temperature their relative effectiveness decreases, making other tires the preferred choice for wet braking.
Braking on wet roads depending on temperature
The material uses 5 types of rubber — Summer, CrossClimate+, All Season, Winter and Nordic.
At 2°C:
- Summer tires: 100%
- CrossClimate+: 123.4%
- All-season: 120.5%
- Winter: 120.5%
- Arctic: 98.2%
Cross Climate+ significantly outperformed summer tires, offering a 23.4% shorter braking distance.
At 6.5°C:
- Summer tires: 100%
- CrossClimate+: 110.5%
- All-season: 109.3%
- Winter: 106.8%
- Arctic: 85.9%
Again, the Cross Climate+ demonstrates excellent performance, with braking distances 10.5% shorter than summer tires.
At 9.8°C:
- Summer tires: 100%
- CrossClimate+: 102.4%
- All-season: 101.5%
- Winter: 97.9%
- Arctic: 78.8%
Near our transition point of 8.7°C, Cross Climate+ continues to maintain a slight advantage, albeit narrower.
At 15°C:
- Summer tires: 100%
- CrossClimate+: 98.0%
- All-season: 98.0%
- Winter: 92.8%
- Arctic: 73.9%
As temperatures rise, summer tires rise out of their slumps and are well suited to that temperature range, outperforming all competitors in between.
Unrivaled performance of CrossClimate+
CrossClimate+ consistently delivered impressive wet braking performance across all test temperatures. In particular, compared to average summer tires they have shown superior or comparable performance, making them a very versatile choice. For those looking for a performance transition tire that offers the benefits of summer tires but still provides better braking performance in colder, wetter conditions, the Cross Climate+ emerges as a top contender. Let us remind you that Michelin has updated its line and introduced the second version — CrossClimate 2.
Such data allows drivers to make informed choices. While each rubber has its own unique benefits and is designed for specific conditions, understanding their performance at transition temperatures is critical. This knowledge not only leads to safer driving, but also leads to better wheel maintenance and longevity.
