Will I rub?

Hi, all. This is my first post and I had a question. I Recently bought some 18×9 -12mm offset wheels with 275/65R18 tires and wanted to know if I'd rub or even just have any issues running them on the stock height? I want to eventually get a lift but I figured wheels with good AT tires would suffice for now. Thank you, and sorry if this has been answered before.

 

First, welcome. Second, yeah the question has been covered ad nauseum.

That's a true 32" tire. A -12 offset on the 9 inch wheel.. you will most likely have some trimming to do. The larger scrub radius from pushing the wheel/tire out is what creates the issue.

A front lift won't make any difference in clearance with independent front suspension. At full compression, your wheel will occupy the same space it would if it wasn't lifted.

Finally, there will be at least one poster who will come in here and share a blog arguing "IFS lift doesn't clear larger tires" is just a "theory".

It never ends. Do your homework and decide.

 

Don't people get tired of answering the same posts over and over again?
This guy already has the wheels and tires, creates an account to ask a question he knows that's been asked many times before and waits for someone to do the work for him.
All this when he can just put the wheels on and see if it rubs.
If he is unsure about keeping the wheels/tires, there is always the search function.

Why do people get more lazy as info gets easier to obtain?

yeah...

 

I think you may have used the term “scrub radius” once before, and it got me curious. I’ve been spending a lot of time since digging up photo references and taking measurements off my 4Runner. It’s late so I’m not going to do too much explaining here, but:
In this first drawing notice the vertical blue-dashed line down the center of the wheel. That is the wheel’s centerline, and most of us assume that when the wheel turns it rotates around the centerline. This is not the case. Now notice the slanted green-dashed line that passes through the upper and lower ball joints. This is the steering axis, around which the wheel actually rotates. The actual point of rotation is the place under the wheel where the green dashed line intersects with the driving surface. @5thToy I know you know this stuff. I’m explaining it for general interest.


Now a top view. With a stock 265/70r17 tire on a stock rim with a +15mm offset. The green dashed line is still there, and one end of it shows the point around which the tire will rotate. The arc describes the path of the front outboard edge of the rim.

Finally another top view, this time with the wheel rebuilt to the specs @SerbGuy described. 275/65r118 on a 9x18 rim with a -12mm offset. I had assumed along with you 5thToy that the front corner of this tire and rim would prescribe a much wider arc than it seems to. But the radius is only ½ inch wider.

I’m still workin out the theory in my head, and there are variables in the alignment adjustments that I don’t have a grip on, but I’ll get there eventually.

(Yes, it’s as much to scale as I can make it without taking parts off the car.)

 

I rub with 17x9 w/zero offset running 265 wildpeaks. Just trimmed the front bumper spoiler last night where it was hitting. Testing it next few days
