BALD winters could potentially grip well, theres way more to it than just how soft the tire is.
It is hilarious that anyone would think a winter tire would have more grip than a summer tire, absolutely hilarious.
Grab a winter tire off the shelf, take a look how deep the tread is and how easy you can bend it with your fingers. How much space there is between the blocks...contact patch is tiny vs a summer tread.
so you're telling me my traction goes down when I put my summers back on in spring LOL.
To follow up; it's not all about contact patch: it's about grip. the blocks are designed to actually 'pull in and grip' the asphalt. Ten years ago, you'd have been absolutely correct, but modern winter tires, and especially winter performance tires, will perform spectacularly well on dry pavement, and will attain that needed temperature much faster (ie. will attain 'grip' temperature on colder pavement) due to the chemical make-up of the rubber. Very little of winter tire's grip is in the tread pattern these days, and again, that's especially true of performance winter tires, which are a relatively new addition to the consumer market.
You will, obviously, give up some deep snow/ice performance with a performance winter tire, but you'll also retain a huge amount of straight-up performance on dry/cold roads, that you wouldn't.
that's actually one of the reasons I chose my tires last year: Even Ottawa only gets maybe a dozen days a year that would jsutify heavy-duty, SNOW tires. the rest of the time, safety (and fun, lets not forget that) are achieved with tires that match the stock spec for size/stagger, and remain malleable, generating mechanical grip, at sub-zero temperatures, dry or wet.
Bald winters won't grip sh1t, just like bald summers won't.: if you believe they would, then you need to do some research into how tires actually work. Contact patch is only part of the equation, mechanical grip through tread design and chemical makeup to retain softeness/malleability are far more important: just as contact patch means very little if you have a 75% sidewall profile.
