17 inch rim Question

[IceDragon]

I want to run a 17inch rim and a 225/45r17 tire, but what i don't understand is offset, how much offset does a DSM have stock? how much offset to make it so the tire tucks in under the fender? to me offset is a foreign language.

I just learned about this myself not long ago, untill then I was confused as well.


I asume you know what a deep dish wheel is? well for example thats a negative offset, now say zero would have the spokes and what not in the center of the wheel, and a positive offset would have them closer to the outer edge.


Hope that breaf example helps. I am not sure what the stocker is.

offset is measured in mm fron the centerline of the rim...

0 means the wheel mouning pad is right in the middle of the rim...

+42 (staock on DSMs if I am not mistaken) means the wheel mounting pad is 42 mm towards the front of the wheel.

stick in the 40 - 45 mm positive offset and you'll be fine.

trucks and some crazy folks run negative offset (sometimes called deep dish rims)

my brother was trying to get me to put on his old pontiac rims which are as you guys call, deep dish, and i knew they wouldn't fit, he was just trying to see what it would look like, but I wouldn't let him disgrace my car like that. Are you sure though that +42 is the stock offset because I see alot of rims that only have a +32 offset

et 35 is not correct for a 2g or a 1g, probably for a honda.

ET42 is what you are looking for on a 2g with 17x7- 17x7.5 rims or 18x7 18x7.5 rims


check under suspension tuning, there are several threads about offset and rim sizing there.


note, what might "fit" does not mean it is a good match. there is a lot more to it than fit, things like where the wheel centerline matches up with the center of the "turning" of the rim etc.

too little offset and they wont fit... too much and it will get darty under braking, wear out the bearings prematurely, and cause torque steer under acceleration.

but mine is not a 2g, it is a 1g, a plymouth laser.

its either the same or extremely close for 1gs and 2gs since their wheels are interchangealble

also do a search for "wheel offset" you will find alot of info
