Living in a rainy area definitely puts a premium on good wet traction! For your 2019 Audi A4, you'll want a tire that balances performance with comfort and longevity. A few folks on Reddit were discussing similar needs for Audis, highlighting the importance of wet and even snow performance, along with decent mileage. Michelin Pilot Sport All Season 4 or Continental ExtremeContact DWS06 Plus are often recommended for this balance. They provide excellent grip in wet conditions without being overly noisy. If you're not dealing with snow, these all-seasons should be perfect. If you need light snow capability, the Michelin CrossClimate2 is a strong contender. Remember, summer tires are definitely *not* recommended for cold or snowy conditions, even if you don't get heavy snow. While I haven't personally used them on an A4, I've had positive experiences with Continental PureContact LS tires in a different car in a rainy climate. They offer a good balance of comfort, quiet ride, and wet traction, although they might not be as sporty as the Michelin or Continental performance all-seasons. Ultimately, the best tire for you will depend on your specific driving style and priorities. Check out some reviews and compare specs before making a decision. Good luck!
