^ Ah, I just wanted to clarify the vehicle fitment.
The problem with cross-vehicle comparisons is that there's often noticeable -and more importantly, quantifiable- differences in the performance of the tires, based on differences in the vehicle on which they are tested as well as the specifics of the fitment.
In the late-90s to early-oughts, overseas testers were among the first to quantify these differences, after which they started to get really specific when they published tire tests: detailing not only the actual sizing/fitment tested but also the vehicle to which the tires were shod during the comparisons.
Personally, while my driving skills fall far below that of any such test-driver and my impressions are further compounded by both the lack of objective instrumentation as well as consistency-in-testing-conditions, my impressions from cross-fitting the same tire/wheel setup from my wife's '05 WRX 4AT to my '05 Legacy 2.5GT 5MT (highlighting transmissions because with Subarus, there's mechanical drivetrain differences in the AWD system based on not just vehicle model, but also transmission type) and my wife's '09 Forester XT (cross-tested with the Legacy only, as that XT and that WRX did not co-exist in our garage), as well as my '13 Tribeca when compared to my '16 Outback (this one's comparison was less biased versus the XT-comparison, as my possession of these two vehicles were separated only minimally in time, with the lease-cycle actually having been due up during our winter months, so the vehicles were fitted nearly simultaneously with my winter setup at the time).
Despite holding wheel specs and tire specs the same each time (I did not make suspension adjustments, although the Legacy's setup changed three times within the 7-year period that I had her, spanning 5 different sets of tires), there were noticeable (but again, I will highlight that I did not take the time to quantify these differences, nor was my driving performed in controlled scenarios suitable for a true comparison) simple objective performance differences (straight-line braking/acceleration in wintry weather as well as in the clear) as well as easily noticeable differences in vehicle NVH. I was able to cross-sample factory OE as well as aftermarket UHPAS, Max Performance Summer, Performance Winter, Studless Ice & Snow, as well as studded winters through these comparisons.
Overall, my humble opinion -based both on my limited personal experience as well as the reasons that various testing authorities have stated towards the subject- is to avoid cross-vehicle and/or cross-fitment comparisons whenever possible as it introduces into the equation too many unknowns.
On the flip side, achieving this ideal may not always be possible. It's a rare day when the vehicle/fitment details match exactly - but still, I try to start my research for my own purchases with same-vehicle-type (i.e. SUV, high-performance sports car, family sedan, sub-compact, etc.) and drivetrain in-mind. From there, I'll hope to see similar fitments (or try to understand what the fitment differences may imply - i.e. different sidewall heights, footprint differences, etc.).
In the end, in terms of the real-world, most times all that we
can do is to call upon our past experiences, even if they are mismatched with respect to vehicle-type or fitment. But when I do, I really try to make a note of that in my mind, so that I can tell myself that hey, I might not get exactly what I had thought I'd be getting. 😅
