Quiet, comfy touring tire; wet grip above average.

I've had the Goodyear Eagle LS-2 tires on my sedan for about 10k miles now and they're really quiet and comfortable on the highway, which I love for daily commuting. Dry handling feels solid and predictable, but honestly the wet grip is just okay, and the same in snow. They've worn pretty evenly and lasted me a decent amount of time, but if you want something sportier or better for winter, I'd look at other all-seasons.

These are by far the best tires I have ever bought

Swapped out the all seasons for all weather and made it all the way thru the 2025 Arctic storm in the north west when you are on icy roads you can feel all the movements allowing for correction and they happen super quick the moment they can gain traction they do.
