Hey, From what i understand ITR's need 73 x 64.15 mm hubcentric rings? Tirerack sent me 73 x 57.10's? will these still work? or no?

 

send them back.. is that what it says on the ring? measure it to make sure... the inner diameter should be 64.15mm... and 73mm.. - measuer the wheel yourself to make sure.. or try fitting the ring behind the wheel to see if it fits

 

hrm, looks like 73x64 when i measure it (well, very close to it anyway, i'm using a tape measurer). the reason i thought it was wrong was they sent me 2 sets, a plastic set that was included, and then the metal set that i ordered.

the plastic set had a 73x57.1 printed label on the package, and they're the same size as the metal ones (when held against each other)

the metal envelope had "64mm" hand written on it, i guess the plastic ones were just put in the wrong package.

guess i'll try and see.

 

ok, scratch that, the plastic ones are in fact 73x57.10's (57.10's is molded into it), but when comparing the inner diameters, there's definitely a difference, good thing i don't need the plastic ones anyway.
