Hello. I'm new to this forum and have a quick question. We have '97 Ram Laramie we are replacing and I'm going to look at a Ram 1500 Express. The listing for it has the standard features for an Express like bedliner and fog lights but, the tires are 17" and the carfax has it listed as a Tradesman. Wasn't standard 20" tires? or was that an upgrade feature? Thank you for your help. I'm not so car/truck bright.
