I've purchased 285/75/16s for my 2002 2500HD several times from Sams. Not sure why I didn't this last time though, can't remember though. I ended up at Discount Tire across the street and they didn't have any trouble at all mounting them up for me.
BTW, I have about 210,000 miles on my factory brake pads as well on this truck...what is it with them anyway?
