I have Falken Wildpeak AT3W that I ran as winter tires for 2 seasons and now have left on my truck for the summer. I would guess 65 or 70,000km on them
i have D rated version on my GMC 1500.
I have run about 2/3 tread off them Still quiet. No issues.
I have noticed some age cracking in sidewall They are 3 years old since I had them Not sure how long they might have sat in warehouse before. I figure I have this summer and one more in them.
AT4W are suppose to be better!
I did buy dedicated winters last year Bridgestone Blizack LT and really loved the dedicated winters as I spend a fair bit of time driving northern Ontario and Quebec in winter.
