2018 New and Worn Summer Tyre Test

今年匈牙利出版物Auto Navigator已經測試了14款205/55R16夏季輪胎，還包括全季輪胎（米其林CrossClimate），全冬季輪胎，以及最有趣的夏季和冬季輪胎。 值得注意的是，所使用的冬季輪胎使用的是去年的測試，而磨損的夏季輪胎是7年，並且已經存放在“次優條件”中，這使得輪胎處於極大的劣勢。雖然未列出每個磨損輪胎的胎面深度，但該雜誌文章表明輪胎仍然具有良好的胎面深度，而不是在1.6mm的法定極限。 所有測試均在約15℃的空氣溫度下進行。可悲的是，該雜誌未對滑水進行測試。

在乾式制動測試期間，全新的普利司通Turanza T005在Primacy 4和CrossClimate中擊敗了米其林。 新冬季輪胎和磨損冬季輪胎之間的差距很大，而且也很難理解，因為冬季輪胎由於較少的滑塊移動而經常在乾磨時會有改進。隨著時間的推移，老化的夏季輪胎顯示出橡膠硬化的明顯跡象，並且只能擊敗單一預算輪胎。

乾式處理總體結果相似，只有米其林CrossClimate從前三名中脫穎而出。

在濕式製動測試期間，米其林Primacy 4被證明是測試的等級，在第二次放置Hankook之前將車停在整整0.6米處。再次，年齡較大的夏季輪胎沒有回答測試，倒數第二。

米其林在濕式處理過程中也表現最佳，普利司通排在第二位，兩個輪胎都領先於競爭對手。磨損的輪胎再次掙扎，最後以相當大的優勢完成。

米其林全季和冬季輪胎被證明是最安靜的測試，Primacy 4再次成為夏季最好的輪胎。

2018 New and Worn Summer Tyre Test

http://www.tyrereviews.co.uk/Article/2018-AutoNavigator-Summer-Tyre-Test.htm

This year the Hungarian publication Auto Navigator have tested fourteen 205/55 R16 summer tyres, but also included an all season tyre (the Michelin CrossClimate), a full winter tyre, and most interestingly worn summer and winter tyres.

It's important to note that the worn winter tyre used was from last years test, whereas the worn summer tyre was 7 years old and had been stored in "sub optimal conditions" which put the tyre at a huge disadvantage. While the tread depth of each of the worn tyres wasn't listed, the magazine article indicated the tyres still had good tread depth, rather than at the legal limit of 1.6mm.

All tests were performed around 15c air temperature. Sadly aquaplaning wasn't tested by the magazine.

Dry

During the dry braking testing, the new Bridgestone Turanza T005 narrowly beat the Michelin pairing of the Primacy 4 and CrossClimate.

The gap between the new winter tyre and worn winter tyre was huge, and also quite difficult to understand as winter tyres often have improvements to dry braking as they wear, due to less block movement. The aged, worn summer tyre showed clear signs of the rubber hardening up over time, and was only able to beat a single budget tyre.

Dry handling had a similar overall result, only with the Michelin CrossClimate dropping out of the top three.

Wet

During the wet braking testing the Michelin Primacy 4 proved to be the class of the test, stopping the car a full 0.6m ahead of the second placed Hankook. Again, the aged summer tyre had no answer to the test, finishing second to last.

The Michelin also performed the best during wet handling, with the Bridgestone in a close second place, both tyres having a good lead over the rivals. The worn tyres again struggled, finishing last by quite a margin.

Environment

The Michelin all season and winter tyres proved to be the quietest on test, with the Primacy 4 once again being the best of the summer tyres.
