I have a bubble on my front left tire...

Could last for minutes could last for years but without seeing it there is really no way to tell and even then it would just be a guess. I would NOT drive this car at highway speeds with a tire like that. You *might* be ok driving around town. Why not just put on the spare to be safe?

Lol you're kidding right? Please say you are. If you actually mean that 15-20 minutes is too much work, then go pay a shop to do it. Have fun loosening your lugs later on after they gun them on at 90,000 ft-lbs.

I have a few lugs on my car that I'm pretty sure were put on at 190,000 ft-lbs. I've put a 4ft breaker bar on there and still can't get them loose. Oh the joys of buying used cars.
