ok 25.4mm is 1 U.S INCH (1&quot;)

so a 17x8 with ZERO offset is 4&quot; backspacing. Take 1/2 the width and thats center or zero offset. if you have any offset over that, say 25mm you add that to the backspacing measurement. Now a 17x8 with 25mm (for an even number) has 5&quot; backspacing...(4 (zero offset)+1 (25mm offset)=5 total backspacing). If it was 7.5&quot; wide rim...3.75&quot; is zero offset....then 10mm would be (3/8&quot;) +.375 or 4 1/8&quot; 4.125&quot; backspacing... and then a 3.375 front spacing (3.375+4.125=7.5&quot;)

10mm = 3/8&quot; (.375)
20mm = 3/4&quot; (.750)
25mm = 1&quot; (1.000)
35mm = 1 3/8&quot; (1.375&quot;)
45mm = 1 3/4&quot; (1.750&quot;)
