Upgraded from 226/60/18's, so there are a lot of changes that come with this review and not everything will be tire related. I put 245/45/20's on the front and 275/40/20's on the rear. Should also be noted that while I like to drive and enjoy giving my car a workout, I'm far from a professional or a mechanic.
I gave 3/5 for snow and treadwear, because I can't really comment on either yet, but am forced to fill them out.
Dry traction they are immensely better, though that could be because they're 5 cm wider in the back. Front is good too, though the car going to a smaller side wall notices many more bumps causeing the front tires to lose contact for a split moment here or there
Wet they are also a fair amount better. Coming onto an onramp, there's a fairly smooth road that if I had to shift down to 1st or 2nd would commonly cause the back-end to break loose in dry and always in wet. The few times I've gone through in wet expecting some fun, didn't happen. Tires stuck and i had full traction.
Comfort, I gave it a 3, but I think this is skewed more so by going from a 225/60/18 to a 245/45/20.
Noise, I've heard lots to suggest that they're noisier, but my engine and exhaust are kinda noisy as it is, and if not, my music is usually turned up. I did my best to listen when on the highway with the windows open and I think I can hear them a smidge more than previous tires, so I'll I listed that as a 4.
Treadwear, as suggested, I can't really comment on yet. 3 is as close as I can give to an N/A
