Okay, I get the label but I want to know where I went wrong. I have a '96 base model 4Runner. I did the Tundra upgrade last winter and grabbed my sister-in-laws 16" Tacoma rims (she had snow tires on them and didn't care about them). Fast forward to this year and she wants to put snow tires back on. I checked the rotor & caliper parts on Rockauto.com and verified that the SR5 and Base were the same. As a favor to her I bought new snow tires and had them mounted on my old 15" rims. She went to have them mounted on the rig and was told by the technician at Les Schwab that they contacted the caliper and she walked out with new snow tires supplied by Les. Now, I think they guy probably saw that the 15" rim rubbed the dust shield and took the opportunity to make a sale but I'm wondering if I just made a big stupid mistake . Did I?
