Thanks for the info. I thought about doing that today. My neighbor works at a tire shop. Unfortunately,his shop doesn't have the tire I want. Knowing Costco, and their stupid rules, they may not sell tires without mounting them. But, I plan to call them today to find out. I think this whole load index thing is bullshit. My GVWR is 5200 LBs, my wife's Caravan is 5800 LBs. My "load index" number is 111, hers is like a 96. My neighbor said that a load index much less than what the Xterra is rated for, will handle much more weight than the weight of the vehicle and anything I plan to haul. I think Nissan includes the GVWR with a max weight trailer, to come up with this. Since I don't tow during winter, I don't think I will have a problem with this.
