I own a 2003 Chevy Suburban with 16in 8 lug rims that are 6.5in wide and I want to upgrade to larger tires and the rims what I currently have are to narrow. Does anyone know what newer Chevy rims would work and give me at least a 7.0in wide rim? I have searched after market options but I do not like any of them I truly like the Chevy rims so for example is a 2015 Silverado 2500HD polished rim would work let me know.

Thanks and Merry Christmas and Happy New Year!
