I'm running 16x8 in Eagle series 058 on my Chevy K1500 Tahoe 2-door. Like them a lot for the price. I'm pretty sure they make an 8 lug version that would fit your 2500.
mine are bare aluminum polished, I put a couple hours every
season with a small buffing tool and a can of mothers
and boy do they look great last the whole summer if I keep
them cleaned off.
