Had to constantly tighten for 50 miles. Finally lost 3 outright and almost lost a cap. I had to turn off the road and backtrack with a stick to pick up a hubcap that had been thrown off the car. Not a very good situation. Luckily I still had the old nut caps which I painted and put back on the car. Pay a little more and get a decent nut cap that will keep you from losing your nut caps and/or wheel covers.
