ok so im looking at rims for a 31 1050 15 but im not sure of the offset i need to get it not to rub on the fram when i turn and i want a wider stance. what are some offsets you guys have gone with?

 

u could go with an 8" rim with a 3-4" offset. depends if u want a deeper wheel or just a wider stance. 3" offset would do both and a 4" would give u the stance and no rubbing with either if ur lifted a lil. stock ul rub no matter what with a 31.

 

its gunna get a 2 inch add a leaf and a tbar crank the rubbing im talking about is the frame when i turn full twist it rubs on the frame. i want a wider stance i dont care if they stick out i want them to see it and say im moving outa that blazers way!

 

Forget about offset and look at backspacing.

Do yourself and your Blazer a favor and stay as close to stock backspacing as you can; 4.5" on 2WD and 6" on 4WD.

 

offset....backspacing, same thing by a different name.

 

Not really. A +35mm offset 8" wide rim will have a different back spacing than a +35mm offset 7" wide rim. While they are related, they are hardly the same thing.

 

its also a 7" rim compared to an 8" rim so obviously different......lol but i get it, my bad.

 

now you guys got me really confuselled.......

 

go with a 8" wide rim with a 4" backspace and u should be fine. i ran a 7" wide wheel with a 3.5" backspace with a 31x10.5 tire and i was fine. is it lifted a lil? if not u may have issues no matter the spacing with a 31.

 

offset is completely different from backspacing. offset is the distance from the direct center of the wheel to the mounting surface of the wheel like a deep dish wheel. backspacing is from the back of the wheel to the mounting surface. a negative offset makes a wheel stick out further. the lower the backspacing the more the wheel sticks out.
here is my blazer with the stock wheel on the passenger side and my new wheels on the drivers side. the stock wheel is 6 inch backspacing im not sure on the offset, the new wheel is 3.5 inch backspacing -27mm offset.
