Well i already tryed searching and i couldent find the answer i want. I want to know what exactly offset rims mean? I already bought new rims and tires, but i am trying to sell my stock OZ rims. I was wondering if 4x114.3 is a offset rim for a 4x100 pattern. I am sorry if i sound stupid but i have no idea what offset is.

 

Read through this:

Offset is how much the wheel sticks out from where it mounts. For example - wheels with an offset of 40 will fit on a lancer, wheels that have an offset of 15 will stick out like those little 13 inch mexican rims you see all over the place. The max I would go is 36 but that may stick out too much for the lancer. my 18's have an offset of 38. 4x114.3 is the bolt pattern on an O.Z. 4x100 is a smaller bolt pattern that scion xb's have. If you want to find the offset on your wheels look on the back of one of the spokes, it should be somewhere around 40 because most aftermarket wheels stick out more that the stockers. let me know it this helps.

 

Ah ok thank you very much. I understand now.

 

offset is basically the distance from the center of the wheel that the hub mounts to it. the greater the offset, the more of the wheel that will be under the car, the less the offset, the more likely you will have the wheel sticking out of the side of the car. offsets are typically measured in millimeters.

here's a calculator for converting the offset when you purchase a wider wheel.

you said you were trying to sell your stock OZ's... i just read a post from some guy looking to buy some... he gave an email of mrand86@gmail.com

 

ur 18's have a offset of 38? what's the width size of your rim? What tire size you running?

i got 215/35/18's 42 offset.

 

215-35-18 / 38 offset / 7.5 inch width. It comes close to the fender but does not rub. Looks great imo.

 

I have 215/35/18 with a 42offset on my car and i was wondering if i should get a 5mm spacer? WOuld that be enough?

 

If you want you wheels to be more flush against the fenders you could...

 

thanks yea i installed it and it seemed to fit
