im looking into buying a set of wheels for my '06 civic si.

im a total noob when it comes to wheels and i need to know about offset. The wheels i want come in +40 and +35 offset. I have no clue what offset even is or what ones to order. maybe someone can lend me some advice on this subject or post pics of the difference thanks in adavance everyone.

This is the best calculator I have seen. You just punch in what you have and what you want to get and it breaks it down for you.

 

+35 is flush.

 

On what wheel?

 

the wheel i want to get is the konig countersteer. (no comments on it being a knock-off) so still what is offset? with +35 will the rim be flush with the fender? BTW im rolling with the skunk 2 lowering springs if that makes any difference

 

Offset is the measurement of the distance of the back of the mounting hub to the centerline of the wheel. If you go to the tire/rim calculator that AJP posted, you will notice the measurement that says offset. It measures the back of the hub to the cross hairs (with respect to the vertical hashed line) that mark the centerline.

A 0 mm offset would indicate the hub right at the centerline, while a +30 mm offset would yield a hub spaced 30 mm outward or away from the car. Inversely, a -30 mm offset would give you a hub that is 30 mm passed centerline, i.e. toward the car.

 

thanks k5! now the real ? is do i go with the +35 or +40 for my civic? maybe pics of both if anyone has them

 

Go with +35 mm. A 5 mm difference is hardly noticeable, therefore I'd go with a minimum of 10 mm difference.

 

I think we'll need a small wheel thread too.

What's the general range of offsets that people are using safely on these cars?

 

Some will go as far as +20. But 'safely' I'd go with +30 to + 55.

 

what is the width of the wheel

 

How wide can you go on an Si without having to make other mods?

7.5", 8"?

 

the konigs i want to buy are 7". anyone know the stock si wheel specs are?

 

OEM: 17 x 7 +45 mm.

 

so why would i not go with the +40? im still pretty confused im looking to get them flush to the fender so +35 or +40?

 

to be more flush your gonna have to run like an 8.5 +35 or so.

 

on an 8.5.

i agree. im on +30 on an 8.5 and i need my fenders rolled.
