The soft tread compound of a Ultra highperformance tire is the main facter of cold weather flat spotting so I don't know if you made much progress with the tire change. The tread design is the main factor of a all-season tire & more cuts in the tread design= more noise & potential for ride disturbance especiall if they wear unevenly. If your wheel & tire have more than 2oz of weight for balancing you have yet to acheive optimum balance. Your easiest 1 step solution is to take your car to someone that does tire balancing with the tires mounted on the car
