I have them for over a year now with 15K on them and down 1.5/32 of tread. In wet conditions, such as rain, road soaked roads and other wet terrain, I found the traction to be outstanding. Dry traction is also very good. Light off-road, the few times I played, no problems. As far as the winter, I have yet to play in those conditions.
With regards to road noise, they have gotten slowly louder than I first got them in the last couple of months. At first, the noise was a little louder than the Latitudes. After my last balance and alignment at the tire shop, they said I had a bad rim. I have to find out from another source if that could cause the increased noise problem which I still have.
In any event, I hated the Latitudes on the GC and overall road traction in wet conditions was poor to dangerous. I would strongly advise to change the tires.
Best for now.
