What Is The Difference Between A P215/5/R15 And A P255/60/r14?
P=passenger tire 215 & 255 are the widths of tires I\'m assuming it\'s \'50\' [not 5] & 60 refers to the sidewall height- it\'s the % of the width. (i.e.- 255mm x 0.50= 127.5mm or about 5.0 in.)And the r14 & r15 indicate rim size tire is designed for.
