Great education on back spacing. Thank you!

 

You know, it's kinda weird.... I bought some 18x9 Level 8 Trackers with 5" backspacing and 0mm offset and my tires stick out a good 1.5" from the fenders.


Here is the front at full lock. I had my GF holding the wheel as far as it would go. You can see where my previous tire/rim set-up rubbed the lower control arm. Doesn't do it anymore...

Here I measured the backspace of the new Tracker rims... 5" it says...


At full turn, not touching the control arm...





All I know is it works good and I did not need any spacers. There is a lot of room for my 35x12.5r18 tires.

 

Your offset is low that's probably why. There is also a c.b. rating that might play a role. Now I need to find out what cb means. Lol

 

I'm not really sure how it works. What is considered low offset? My offset falls right in the center of the rim.

 

12" measured width with 17x9 with 4.6" backspacing:





About 1.5"
