What backspacing/offset for 09 chevy 1500 lifted??

    I just got an '09 chevy 1500 4WD. I'm going to go with a 7.5" lift and 35's but I don't know what backspacing or offset (negative/positive) to use to get the look I want. I'm going to get 20x9 wheels and I would like the tire to stick out but at the same time not degrade spindles, bearings, etc... Right now I'm thinking 20x9", 4.5" backspacing, and negative 12mm offset????

    I've seen some pics of some awesome lifted trucks like mine, and I would like to know the exact dimensions of the wheel that was used. Include a pic if you can so I can see what it looks like.

    I made the mistake on backspacing before with my last truck, the wheels were even with the body, don't want to spend all that money and make the same mistake.

    Thank you!

    Welcome to the forum, that backspacing sounds right but not sure on the offset.

    Welcome to the site. I have 7 1/2 inchs of lift with 20x9 rims with 35 inch tires and went with 5 inch backspacing and zero offset. You can look at the pics of my truck on my profile. Someone can correct me if I am wrong, but I have always heard it is better for your bearings to stick to as close to zero offset as possible.
