Hi all,
I've had them for only a week, so I haven't had a chance to try them in any kind of appreciable snow conditions. In my opinion, they don't seem to be any noisier than the Eagles on paved roads. The street in our subdivision is hard snow-packed, I ran it up to 40 klms and hit the brakes hard, expecting the anti-lock to engage... much to my surprise, it didn't engage at all, very good feel as the Murano stopped very well.
The cost for the GrandTreks was reasonable ($150 / each through Coast Tire), considering the rarity of that size tire.
PS: The Murano is now fully winterized for our Maritime climate... real winter tires, 24 inch teflon blade for the driver, 19 inch winter blade for the passenger, cargo liner and floor mats from Weathertech. The only thing I would have liked to obtain is plain black wheels so I could change the tire/wheel package over before each season.
One drawback I think you'll notice with the stock spoke rims is that if snow gets built up in the Offset area behind the rims, this will throw off your wheel-balance something serious.... will cause your steering wheel to vibrate until you get that snow / ice out of there.
That's it for now.
Have fun in the snow.... I know I will.
