Boss 338 offset / back spacing ?
I have an 81 C10 with 4.5 front and 6 rear and want to buy some BOSS 338 wheels with 20x8.5 front and 20x10 rear..... what is the best back spacing for them? Also what size and type of tires do you all recommend to go with them? Pics also appreciated with your set ups.

I've seen several for our 5x127 pattern squares.

I ran them on a 82 with a 4.5" & 5" drop with 245/45 and 275/45 tires. They only have 1 backspace option best I remember.

Re: Boss 338 offset / back spacing ?
They offer 2 backspacings 5.25 & I believe 4.75 on the 20x8.5's.
I went with the 5.25 back when I had them on my truck. Worked out great and ordered my billets in the same backspacing. 20x8.5 with 5.25 bs w/ 255/35/20 front & 20x10 with 5.5 bs w/ 275/35/20 rear on both sets off wheels. Last edited by JWall; 11-22-2016 at 10:52 AM. |
