What's the perferred backspacing for 20's on a NBS ECSB? tire size?

20 x 8.5 with 6" of backspacing is preferred.

on a 20x8" wheel you'll want 5.5" of backspacing! :bowtie:

some say 35, series, others say 45 series... there arent too many 40 series tires that will fit that wheel's width properly. I would say a 40 series sidewall tire with that size drop and rim.

I'd say that anywhere between a 245/40/20 and a 275/40/20
