Great Post!!! ive found that within the installs that ive done this is pretty accurate. Except for I would Note that almost anything in yellow COULD be in the red depending on the vehicle. IE: a few weeks ago i did a 3" kit and 285 70 17s on the stock sr5 wheels and they rubbed the sway bar at full lock. every vehicle is made slightly different and thus amounts of rubbing can vary.

Therein lies the problem...SR5 is 7" wide wheel and a 285/70/17 tire is rated for a minimum of 7.5" wheel..could have something to do with it.

This is where the wheel width is going to be a problem. Wheel width requirement varies by tire make. For example, the Nitto Dura Grappler in a 285/70R17 is rated for a 7-9" wheel width.

Easily fixed. Poof! I put "suggested" on the wheel width.

Haha, it wasn't my intention to change things up. The reality is, people need to do their research and merely use this as a guide. I know that's your intention but you and I both know that people will take this as written in stone.

And to make things worse, if you compare a 285/70/17 BFG A/T to a Nitto Trail Grap you get 32.8 and 33.15 respectively.

I just hope people are more intelligent than I'm giving them credit for.

After over a decade in IT, I can assure you they are not.

Updated the original post to include stock TE wheel backspace. Remember for reference this chart is now located here http://www.toyota-4runner.org/5th-ge...inks-faqs.html

So I think I have figured out how to help some of you who have trouble with wheel offset and backspacing. I am working on some real world examples that I will post when completed. These will be common fitments with detailed explanations so they can be used as a template for future applications.

So I'm guessing if I plan to lift my runner, but I'm going to get tires first (limtied on funds, so it will be awhile before I lift it) then I should go with 285/70/17?

I think you have to look deeper into the tire brand specific dimensions. As mentioned above a Nitto vs BF Goodrich in 285/70/17. There doesn't seem to be uniformity in the tire industry with regard to the tire size specs.
