Replacing all four tires at a tire shop typically takes between 45 minutes to 1 hour. This assumes the following:

The shop isn’t swamped with customers.
The technicians are experienced.
The service includes removing your old tires, mounting and balancing the new ones, and installing them on your vehicle.
Here are some factors that can influence the amount of time it takes:

Shop workload: If the shop is busy, you might wait longer before they can start working on your car.
Tire size and type: Larger or specialty tires may take a bit longer to mount and balance.
Additional services: Balancing and alignment checks after installing new tires add extra time.
Tips for a quicker turnaround:

Make an appointment: This ensures the shop has a technician available for your car.
Drop off your car: If possible, leave your car at the shop instead of waiting while they work.
Ask about wait times: Call the shop beforehand to inquire about their current workload and estimated wait times.
