Have a question about Cosmo CT778 Plus tires?

No, the Cosmo CT778 Plus is not an all position tire. The CT778 Plus is designed for use on the drive axle of heavy commercial trucks.

Yes, the Cosmo CT778 Plus can be used year-round thanks to its three rows of grooves and blocks with a closed shoulder that provide reliable traction in dry, wet, and light winter weather conditions.
