    Hi everyone.

    First I wanted to thank everyone on the site. I have gotten a lot of useful information here. Have been lurking and searching for the last 2 months, but I can't find an answer to this particular question.

    When I bought my truck I put 265/75/16's on because I wanted the biggest tire without a lift. I was planning on keeping my stock rims, which are the chrome plated "Gulf states toyota" issue 16's.

    Well, the mod bud has kept creeping up and I want new rims. I want to keep my 265/75/16 tires. I see that the various stock wheels are mostly between 5 and 5.5 backspacing. However, every aftermarket rim I find in a 16X8 seems to be 4.25 to 4.5" backspacing.

    My question is, is anyone running a 4.25 or 4.5 backspacing 16x8 rim with 265/75/16's with stock suspension? If so, did you have to do any trimming to avoid rubbing? Thank you.

    I contacted a member who has 265/75/16's on a 16x8 wheels with 4.0" backspacing, and he said that they rub, even after removing the mudflaps.

    So it seems like 4.0" is too little backspacing. Anyone out there running 4.5"?

    4" BS puts the wheel further away from the suspension. 4.5" will bring the wheel closer to the suspension. 4.5" or less is what you want. The rubbing can be easliy fixed with some minor trimming.

    So people are running 265/75/16 with 4.5 BS with no problems?

    When you say 4.5" back spacing or LESS, do you mean closer to suspension or further?

    I can't go much less (further from the suspension) than 4.5, because 4.0" apparently rubs on the outer edge of the tire during turns.

    yea its kinda backwords. So when he said 4.5" BS or less, it brings the wheel closer to the suspension/spindle. a lower number representing back spacing, 3.5", is considered a higher backspacing since it pushed the wheel further away from the suspension/spindle.

    Tires size and rime size can sometimes be the most confusing thing. Good luck. Hope it works out.

    Thanks everyone. I understand backspacing and offset just fine. All this really comes down to is what is the range of backspacings (on the high and low sides) that will allow for a 265/75/16 to fit without rubbing.

    Specifically, who here has 265/75/16's on a wheel with 4.5" BS, and does it rub?

    5.5"-4.5" will get the job done
