I'm tempted to change my seasonal tires to cross-climate ones, but I'm considering changing them progressively, to wear out my seasonal tires. Is it a very bad idea to let's say have on the front two cross-climate and on back two seasonal tires? I've heard mixed opinions, but does anybody have experience?
Having driven a car with four different tires, I know it is very unsafe to do so. That being said, although different brands/makes of tires used in combination is not recommended, Continental Tires provides an excellent article on the subject.
