Help with offsets

[philipfreire]

Hey guys,

I'm going to be going with a 225/40/r18 wheel. Will I need an offset? Will there be rubbing on the turn? Will the offsets make the tire fill the fender side better?

If so, what offset do I need? How much do they go for?

Offset isnt a price my friend.. its the distance from the hub to the bore of the rim. Higher the offset the less likely you will rub.
Im at 50 and compared to a 45, no major rubbage.

oh.. i mean spacers then?

you can get away between 2-5mm... Im going to try out 2MM for sh!ts and giggles. but if you have a 45 offset negative camber is what you'll need to achieve this look without rubbing.

Oh wait.. your running 225.40.18

you dont need spacers....

[S.F.W.]

Unless you are specifically trying for a "flush" look, with the high offset of the Speed6 rims, you will not rub wit a 225/40/18 tire.

how do i find out my offset? like im getting my ms6 wheels put on maybe this week.. and i 225 is much wider than normal.. but is that a safe width that i should get no rubbing when turning fully?

right now my concern isnt about making it flush.. just no rubbing..
