Some high performance tires have speed ratings. Speed rated tires will generally have a softer tread to aid in traction and a rigid sidewall that increases the performance characteristics of the tire. The softer the tread, the quicker the tire wears. Technically speaking, speed rated tires are designed to be stable up to and at the rated limit and range from Q being 100 mph all the up to Y being 186 mph.
Yes, there are actually extreme differences between not only summer & winter tires but all-season tires as well. Winter tires will have bigger grooves for snow, some actually designed to grab the snow and throw it as traction. Winter tires also have softer compositions then all-season tires. Summer tires will have enough groove for rain and keep more rubber to the road for dryer conditions.
Premature tire wear may be caused by many factors other than tire rotation. Some examples are as follows: improper inflation, driving conditions, misaligned vehicles, worn vehicle parts and a variety of other reasons. Without physically inspecting the tires, it is difficult to make a determination as to why your tires wear prematurely.
