17x7 - 4x100/114.3 - 42

17x7 - 4x100/114.3 - 40

what do those numbers mean? and what do you reccomend?

 

i believe its the sidewall height of the tire

 

Believe the last # would be the offset (-40mm or -42mm)

 

The difference is the offset of the wheel. +42mm offset vs. +40mm offset.

If you are torn between the two wheels, go with the +40mm offset. The difference is really not even noticeable, but it just may help avoid suspension conflicts. You might also want to run a set of spacers with those. At least in the rear.

Really though, get whichever wheel you prefer. Like I said the difference is negligible. 2mm is only 0.079".

 

nvm i was thinking about the tire not the rim, discard my stupid comment lol. what would be a good offset for the tc
