I'm once again looking to purchase 15" rims for my 69 442 and am questioning what I should look for in backspacing for what ever I buy. I would like to find either Torque thrust or Torque Thrust II rims to replace my 14" SS2 rims.
What would you guys suggest that I should go for the Max backspace that will both not cause any wheel rub and still fill the wheel wells. I want 15x7 on the front and probably 15x 8 on the rear.
Pics would be great
Thanks

 

Backspacing is unrelated to wheel diameter. You want OFFSET to be near zero. Backspace for zero offset will vary with wheel width. A 7" wide wheel will be about 3.75" backspace for zero offset. An 8" wide wheel will be about 4.25" backspace for zero offset.

 

I saw that Padavano Mini Sermon coming from a mile away.


From what I gather, the stud mounting plane of the Olds hubs is about split 50/50 from the wheel well opening edge on the outside and the inside, hence the near zero offset. There is, of course a finite limit on how fat the wheel can be just to fit IN there.

 

 

I put a smiley on there. I too appreciate Joe's advice, and it was meant jokingly, as people who don't miss social cues would be able to tell.

 

I took Koda's comment in the spirit that it was intended. We've traded good-natured barbs like that for years. No offense intended or taken.
