Really I'm trying to get snow tires. The options in 15" have pretty much dried up. But many good snow tires are still made in 16". I was looking at a reference book at the tire store and it listed a 16" 5 on 5 rim as an OEM option on '88 to '98 GM 1500 series trucks. So that's what I'm looking for. However, none of the junk yards around me have any and most claim there's no such thing. Any help appreciated.
