Aragorn Posted June 7, 2009 Share Posted June 7, 2009 285 x 0.75 = 213.75mm 305 x 0.7 = 213.5mm thats the sidewall height. If you double that and add on the rim size (for reference, you can see they're the same from the sidewall height alone in this case because the rims are the same size): 285: 406.4mm (16") + (213,75mm * 2) = 833.9mm 305: 406.4mm (16") + (213,5mm * 2) = 833.4mm So they're both basically the same, just under 33" Quote Link to comment Share on other sites More sharing options...
