First impression? DEEP tread.
This wagon has a manual tranny. Automatics will not see the same cornering results.
0-300 miles: The factory protectant layer lasted for the first 200-300 miles. You can expect reduced handling during this time period. The first thing I did was to drive up Timberline Lodge in dry 55f weather at 6k ft elevation. It cornered well, but the protectant noticeably acted as a grip retardant. Two tires had no need for balancing on the factory steel wheels.
300-1500 miles: It sticks to rain-slicked surfaces with utter ease. The tread cuts through standing water of up to 1/8 with little pull to that wheel be it interstate concrete or highway pavement up to 60 MPH. 65MPH has sheds less well. 70MPH has light hydroplaning issues at a touch above 1/8 water. 0-1/8 water is largely known by wheel well spray. Portland, OR industrial-road puddles? Laughable.
High speed wet severe corner grip is purely dependent upon my wagon's balance when in the power bands. Freshly wet/tar-slick pavement after a dry hot spell is unknown.
Alpine highway driving (40-45F at night) showed that it handled well in the dry and wet as long as I stayed off the sand. It did NOT corner well if I drove on the damp light sand at highway speeds. 45MPH was the max comfortable speed if I had to deviate from the tracks.
They grip very well even with 60-70 degree gravel roadways in the dry. I was able to track right through water channels with ease going up or down at low speeds. After driving on such graveled driveway/roadway angles, 55-60MPH highway speed shedded nearly all of the rocks by about two miles down the road, but pelted the wells for the first mile.
Forest service and back country roads are easily handled when surface-wet at max posted speed limits.
They help resist wind walking when compared to past tires.
Simply put, these tires are so far in my opinion a near-optimal choice for PNW driving west of the Cascades outside of studded seas
