Bought these to replace the stock GY Efficient Grip Performance RUNFLAT on my Active Tourer, which had 3-4 mm of thread and almost 70000km in the (4 yeras old). Grip was problematic in the old ones.
Have drive the Sportrac 5 for about 10000km since march 2019 when I fitted them. First impressions were off course positive: much grippier tire than the old and worn GY. But although they are very grippy in dry, but most noticeably in the wet, I would say they are a harsh and noisy tire. These are not runflat tires and with the same preassure front and back, I did not see much improvement with regard to comfort, maybe because they are the XL version with stronger sidewalls. Secondly: they are very loud in comparison with the old and worn GY.
my conclusion: grippy, sporty tire, especially in the wet...but harsh and noisy.
