In the latest Commercial Truck Trader Magazine, I saw a photo ad of a Bullet sitting on a dealer lot in Texas. Without question it has aluminum wheels. (no lug covers or hub covers). Also, the front page of a Sterling Bullet color brochure I grabbed in Houston clearly displays a Bullet with aluminum wheels with "chrome" lug covers and hub covers... ... I am wondering if these are the same 10 lug aluminum wheels optioned on the Ford 450/550? I am in the process of puchasing my 5500 from Chaprell Dodge/Chrysler in Ada, Oklahoma, and they said they do have simulators in stock for the 4500/5500's. Personally... ... . I think wheel simulators look a bit "cheesy" so I will be researching the wheel spec's on Ford 450/550 aluminum wheels to see if they are a direct swap.
