I'm not a car expert. Having purchased a 2015 RX450h a year ago after a lifetime of driving underpowered "consumer" vehicles, I've found myself delighted and more interested. My experience is limited yet hope it may be of value here. The car came with two new sets from the prior owner: Nexen NFera RU5 summer tires and Yokohama IceGuard G075, both used at 8000' elevation in the Colorado Rocky Mountains. I live at 5600' where the Great Plains literally meet the Front Range foothills. Our snows are intermittent and almost always melt quickly; in all but the most severe storms the roads are cleared overnight with no glaciation.
The CrossClimate2's (hereinafter CC2) came to my attention and as I presume you know are already well documented both technically and experientially in YouTube videos. I privately sold both tire sets and mounted the CC2s in April 2021 during the end of our winter snow season. My prior experiences are driving a '98 Jeep Grand Cherokee, an '08 Honda Civic, and an older Camry and Accord, and drove with both Nexens and Yokos on the RX. I average 7000 miles/year. I don't push things; not a fan of G forces, especially on crowded urban roadways and highways, let along high Rocky Mountain S curves.
Here's what I can offer so far:
- Comfort/dry: the CC2s ride like ghosts…as if they're not there. Now this is on a Lexus RX that itself rides silently and smoothly. Yet I also feel their enhanced grip compared to the other sets.
- Snow/braking: I tested the CC2s in an empty parking lot one night with 4-5" of spring slush. I started at one end and floored it to the middle of the lot in the various drive modes. Zero slippage whatsoever except for 2 merest blips of the traction light. In the middle of the run I braked hard, and as the runs when on, harder. Zero skidding and, assuming that Lexus ABS braking feels and sounds like what I've experienced prior in lesser cars, it never engaged in this testing.
I'm completely sold. First, for never having to swap tires, wheels, etc. That's a big time, effort, and money saver. Next, the CC2s with their street-legal snowflake winter designation, stellar personal test performance, and video performance in the Swiss Alps indicates that I ought to expect very secure snow performance even to 8-10" on my 5000 lb SUV.
