But you all have to think about this.. alot of the time you need to most
traction, your tires are not equally loaded!! In a left hand corner your
front right may be taking 40% of all the weight no? And wouldn't this be
where a wider tire comes into effect? Having a wider tire means more
possible contact patch, with a smaller tire you can only go so far
before your sidewalls are becoming part of the contact patch?? Just a
theory
