can someone explain the 3 numbers on tires...i know the last # is the size (17 or 18s etc), first is mm and second is ratio..but i dont get the importance...also importance of mm hub rings? can someone explain...how do i get 63.5mm hub ringsOriginally posted by: Iceotron
you need a 40 or 42 mm offset to be worry free. Also with most rims you'll need 63.5mm hub rings as most rims come bored as 73mm which leaves the cars weight on the studs and not the hub where it belongs. Please check the wheels, tires and brakes section for more info. Also this post will proll be moved there.
Any upgrade in rims will give you a larger wheel gap. I have 17's and the rear looks good, but you could fit a football in the front gap! It will still look good, but you will definitely want to lower it when you see the way your car looks with them on. You can click on "See My Car" to see how mine look. Right now I don't have it lowered. Also, to answer an earlier question, our bolt pattern is 4X108.Originally posted by: PeDL2DaMeDL
Right now I don't want to put money into lowering springs...would 17's look fine w/o them on my coug?
As long as the rim/tire aspect ratio overall is the same the wheel gap will NOT change. However the appearance will, and can fool one into believing there is more or less wheel gap.Any upgrade in rims will give you a larger wheel gap
