Why do some people run tall slicks with a deep gear ratio?? Why not run shorter slicks with something more like a 3.91 gear ratio? What is the comparison? are 3.91's and 28 inch tall tires about the same as 4.10's with 29's? 30" tires with 4.56?? Do you have to run a taller tire to get the real wide slicks? Just thinking about this today and wondering why why why.
