Ok, is my math wrong or what but 225-50-15's hav a sidewall height of 50% of the width which comes out to 112.5.... 195-60-14's are stock on this vehicle and 60% of 195 is 117...... 205-50-15's 50% comes to 102.5 thus throwing the speedo way off am I correct? Thanks for all the respons so far... Rich Andrews rjandrew@post.cis.smu.edu
