...the nut back on? is it alright to drive it on 3 nuts like that, its the front passenger side tire, new front tires, have to go to airport soon, but is it alright if its on 3 nuts?
It should be okay for a while (make sure they are tight) but eventually you will want to go to a shop and have it fixed. they may have to drill it out over-sized and then insert a helicoil but this is not uncommon.
