I think your cost-benefit analysis is off track. One set of Kenda or IRC tires runs around $200 if you mount them yourself. A single tire for my Chevy HHR costs more than $200 making a set of four tIres cost the more than 4 sets of motorcycle tires rendering the 60,000 miles a wash.

A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort. Herm Albright (1876 - 1944)
