I think section width is not the issue. That tells you how wide the tire is.
Aspect ratio is a larger concern. That ratio gives you the tall or short sidewall.
section width / aspect ratio - wheel diameter
275/60-15
275 is the section width. Nice and fat. 60 is the aspect ratio. 60% of the 275 mm width. 15 is the wheel diameter.
OHHHHH....
This is good info.
What about backspacing? and bolt pattern?
I'm guessing the pattern on the 74 cuda is 5 lugs x 4.5" centers.
What is my backspacing min/max spec?
I dont want to use spacers.
Thanks again.
You can use this thread as a guide, do the math on subtracting the spacers I have to figure out the backspacing. Keep in mind manufacturing variation can be pretty large on these cars, you mileage [and tire clearance] may vary.
