I test fit with the OEM lug nuts, they fit the seats just fine, and offer enough clearance so I don’t think I’ll replace them. I did get new tpms sensors too, so now I’ll have a dedicated winter wheel/tire set and the 3 season wheel/tire set. As for the tires, they are 20” that I used on my S8 for a few months and the sizing is a little off from the Pacifica OEM size, but it should only impact the speedo by a couple mph. So I’ll run them for a few years before replacement, hopefully. But they fit nicely on the S8 9” wheels so they should be fine in this application as well. I forget the size, but I’ll report back after I get them mounted, hopefully this weekend. I just got my truck out of winter hibernation so now I can ferry the wheels and tires to the tire shop without getting the van all messy. Well that, and the fact that wheels and tires separately take up too much space to fit in the van with all the kiddos seats in there. But I’ll post up pics once it’s all done.
