another rim question

I ordered some 17x10 with 35mm offset but it is rubbing in the inside with the rear subframe. I only ordered two try it out. I am going to send them back and i'm thinking going with 18x9.5 with a 45mm offset. Will i have the same problem? i'm trying to avoid using spacers? i attached some pics...

Wouldn't you want less offset instead of more?

I'm not 100% sure, but offset is offset is how far from center the hub attaches to the rim. So i think that a bigger offset will make the rim fit...

More offset will put the rim even closer to the subframe.

Interesting, when i called to ordered the rims they told me that 40 to 38 offset would work best. I was going to get a different rim but they told me that it only came in a 28 mm offset and it would make the rim stick too far out...

right now i have a 35mm, so you saying i should go with 12mm or a 10mm to make it fit without rubbing? i'm thinking about getting bigger rims so if it is so then 18x9.5 with 12mm offset would work best? take a look at the site attached.

If you've got enough room between the outer edge of the rim and the inner edge of the quarter panel to allow the rim to come out and hit neither the subframe or quarter - then less offset will work (probably around 30-32mm......my 18x9.5's are 35mm offset on the rear)

If its going to hit the quarter panel if it comes out more, then its simply too wide, but a 10" should fit, but the offset needs to be spot on, and the quarters may need to be rolled slightly.

You got spacers? i just received 17x10 with 35mm offset and they are rubbing with the inside frame, but i don't want to use spacers (see the pics) above. thnxs

no spacers on the rear for me.

EDIT: you need a lower offset as mentioned. That will setout further from the hub. Like I said, my 9.5" doesn't rub with a 35mm offset, but yours is 1/2" wider with the same offset......so it hits. Lower offset or narrower rim, just make sure you have the required clearance between the outer edge of the rim and the quarter panel lip.

offset is the distance from the hub to the center of the rim. so the bigger the positive offset the deeper the rim sits towards the car. kinda works like camber. negative camber has the bottom of the tires away from the car and positive it is closer to the car. thats how i remember it.

I wouldn't go more than +40 on a 9.0" in back.
With that said, I wouldn't go more than a +35 on a 9.5" wide.

I'm not surprised the 10.0" hit with the +35.
I wouldn't go more than a +25 with the 10.0", although the numbers look like it'll work with a +30.

When I test fitted a 10.5", +9 with a 295 tire, it had maybe another 1/4" before hitting the insides.
With the 10.5", I try to stay above a +15.
