How long to get your set of tire replaced?

I am going to get my set of tire replaced in discount tire. How long do you think I should wait to get the job done?|||As long as it takes. It's a tyre store not a pit stop. Why not ring them up and ask what their queue looks like today?|||shouldn't take longer than an hour i can usually knock out a set in 35-40 min, quicker if they have 2 guys, one to mount other to balance.But also depending how soon they can get you in when you arrive, generally its a good idea to call ahead or stop in and ask how long it would take to get you out the door.|||Call them and ask how long it takes.|||Plan for at least a week...to fit into your busy schedule.|||About 20 minutes if they're not busy. About 2 hours if they're busy.
