Most likely because of unbalanced tire. I have had exectly same situation driving my Ford Escort, vibrations begun at 75 miles per hour and became unnoticeable after 85 miles per hour. After tires replacement and balancing vibrations dissapeared completely. I am assuming that after installing patch on the flat tire, that tire became unbalanced because of weight of that patch. If you have patched you tire I suggest you visit mechanic and have that specific tire balanced. Mechanic will install counterweight on that tire on the side opposite to patch and weight of balance would be matching weight of that patch. That way tire stays balanced and will not cause vibrations anymore. If you have recently patched your flat tire and you have full size spare tire in the trunk, try installing it instead of patched tire and see if that will help. Hope this helps.

Not all Altima's vibrate. If the car is vibrating, it may mean that there is something wrong with the tires.
as a result of bad spark plugs
You probably need new rotors
Yes.
If a sound can reach the frequency the glass atoms vibrate at, it can be broken
That happens when your car wants to kill or injure you for crashing it.
