: Wheel Offsets Question

Well my question is just as the title sounds. I just picked up a set of American Racing Casino Wheels (Black center w/ machined lip) size 17x7.5 w/ 215-45-17 tires. The offset of these wheels is 45mm, and the distributor had a program that said they would fit an all, but...
what is the offset of the wheel. My logic would say that it is the distance that the lugs are placed from the center of the wheel towards the lip. In example, a 45mm offset would have more of a flat appearance, and a 35mm offset would have a deep appearance. Is this a correct assumption???
The place i ordered these wheels from is including a 'tuner lug kit' that is gaurunteed to make them fit my car. Question #2 is how will these wheels fit/look on my car with this 45mm offset. I was aiming for the flatter appearance, but never really took into account the offset, I just really liked the style of the wheel and bought on a whim.
I'm probably just paranoid, because I usually don't spend this much money, but I would feel a little more assured until the wheels arrive to know that others have put wheels of this size and offset on their Saab. So any advice/inputs/comments would be great, Thanks!

45mm will bring the wheel awefully close to the suspension and inner fender.

35mm pushes it out.

Thanks for the replies so far, but...

My question now is has anyone put on wheels of the same size and offset (17x7.5, 45mm offset)? If so were there any rubbing issues etc... I read through the links that were providied in the prior responses, and it sounds like 49mm is th breakinig point for making all clearances and not rubbing, therefor the 45 mm offset on these 17" wheels should work perfectly fine..is this a correct assumption???

I've got 5 spoke Aero rims (SAAB # 400133377) on my NG 900. I'm pretty sure the rims have 49 mm offset and the tires (215-17) were way tight to the front suspension, maybe an 1/8"-3/16 clear. 15 mm (shaved to 12mm) spacers fixed it right up.
No spacers on the back and I do get some occasional rub on the fuel filler neck. I added a pvc 'wear plate' to the filler neck until I find some good 10mm HC spacers.

Good Luck

Wouldn't you want a wider track though?

45mm makes it narrower.


I admit it's marginal, but still...
