Driving in the snow takes some getting used to, and snow tires are always a good idea. The best snow tires for a Kia Optima—now known as the Kia K5—are Bridgestone Blizzak WS90s.

Snow tires are made with a type of rubber that stays soft in cold temperatures and feature a chunkier tread to give you added traction in snowy conditions. Other great winter tires for the Kia Optima/K5 include:

In addition to giving you increased traction in the winter, adding winter tires to your Kia could qualify you for a discount on your car insurance.

If you can’t find a good winter tire for your Kia Optima, you can get away with using an all-season tire like the Michelin Defender T+H, though you’ll want to be a little more cautious with your speed and your turns.

It’s also a good idea to ensure that your car insurance is up to date for the winter. Slippery driving conditions cause accidents, and solid collision coverage and liability coverage can give you the peace of mind you need to get through your first Colorado winter.
