While prepping for a drive tomorrow I noticed the far side front wheel of my car has one stud out of five that is somehow loose. All other four studs are secured and tightened. By "somehow" I mean that the stud seems to be turning along with its lug nut, although it requires some force to be turned (can't turn it with fingers, but with a cross it does turns easily). I'm not trying to tighten it more as I don't want the thread to possibly give in.
The car is a 2007 Civic Type-R Euro (FN2) with stock alloys (5x114.3).
Since I'll have to drive a couple thousand kms tomorrow at highway speeds, I'd like to know if I'll be safe driving at 110~130kph for an extended duration. Additionally, is there any precaution I should take to be more safe?
