I bought a set of these after hearing a few other owners got them for their winter tires. Now Kal Tire is telling me that they do not have and cannot get appropriately-sized hub centric rings, and that I'll have to get them custom machined for $120/ea. For folks who have them: are you running lug centric, or do you have hub centric rings that fit, and if so where did you get them and what size are they?
