Alright, I'm waiting for the snow or maybe not.
I am really taking a shine to the S4s. They are probably the best tire I've had in 6 or 7 years since I kissed off larger vehicles and started driving things that ride on 175 section tires. You can't get a really good 175 - 14 summer/all-season tire like an MXV it seems.
The S4s are really very smooth and quiet and have tightened up the handling of the Echo considerably. I won't be calling out any GTis though.
In the recent torrential downpours, it did extremely well. To top it off, fuel usage seems to have dropped slightly. They are definitely tighter than the Nokian WRs but it is hard to imagine the performance the S4s are showing now will hold up just as well in snow and ice. If it does, they will get a 5 star rating.
So we'll see.
Cheers,
John M.
