17" x 7 wheels for an 1990 gxl What is the offset limits for this size rim with stock skinny *** tires with no problems ???? . 38 to 045 ? is there a chart quide or simple websight out there for the 2nd generation fitmen ... thanks .. looking at 17" x7" 5mm ADR Akunin wheels with a : 45 ! offset ...
thanks in advance

 

stockers are 7" and +40.

Click the links that are stickied in this section. There is an offset chart in one of them.

 

thanks for the info , although i couldn't find the chart , if 40 is norm would the 45 offset + 5 move the wheel in or out from the fenders ? also dosn't sound like much of a move , especialy with 7" rims ??

 

The wheels will be 5mm deeper. They'll look too sunken it the wheel wells for me, but that's just personal preferance.

 

That is the chart I was referring to.

Yes, +45 versus +40 would not be much of a change, only 5mm, as mentioned before. However, I have not ever actually measured the space between the wheel and the suspension and fender before, so I'm not sure how much 5mm would matter.

 

im having a really hard time making sense of that chart.. what are those figures suppose to be saying???

 

+45 is too much.
You might get away with like a 205 wide tire, but I don't think you can go wider (tire) than that.
Find a +35 width for a 7" wide wheel, and you get lots of choices for tire sizes.


+5 the wheel goes inside the well.
+5 is almost 1/4", and to me THAT'S a significantly amount of space, since the stock 7" +40 is already too damn tight.

It is pretty simple, with a 16" wheel roughly 24.5-25" in diameter you max out at 6" backspacing the rear, and 5.6" in the front. To determine backspacing, you take the difference between the actual centerline of the wheel, and the mounting surface. If the mounting surface is towards the outside of the car, and the centerline of the wheel that is a positive offset, if the mounting surface is towards the inside of the centerline that is a negative offset. I run 16x12 0 offset rears, and 16x11 -12.5 offset fronts on my widebody. These numbers are based on a 2.5" spring. You can get more room up front a couple of different ways, but in the rear the trailing arm is the limiting feature.
