Backstory: My Corolla came with 16" alloys/all seasons. Last fall I bought some 15" steelies and snow tires, had the shop I bought them from install them. I swapped my tires back to the all seasons myself this past spring. Now I went to install my snow tires this past weekend and I noticed that the lugnuts that were used for the steel wheels/snow tires were much harder to thread onto the studs than the set that I am taking off with the 16" all seasons/alloys. The lug nuts with the all seasons tires/wheels are able to be freely spun with my fingertips until contacting the wheel (and then I torque them down with a torque wrench). Or once I initially loosened them I could spin them the rest of the way off with my fingers. The lug nuts with the steel wheels/snow tires are only able to be threaded on one or two spins by hand before I can't turn them with my fingers anymore (they're not hitting the wheel yet). Is it normal for some lug nuts to be harder to thread than others? I don't want to force them on with a ratchet or impact gun and mess up the threading on my studs. Thanks for any help, I plan on stopping by the shop after work and seeing what they say.
