Looking for somebody who has actual experience with BOTH of these. SP 8000 should handle a lot better in both wet and dry, providing superior braking as well. SP 4000 should have better tread wear, snow traction, ride comfort and should be less noisy. If anyone can compare both of these in each category and state HOW MUCH of a difference there is between these tires, I would greatly appreciate it. I am especially interested in finding out the difference in show traction, braking, and ride comfort.
