A truck with runflats can take up to 8 hours costing about 800.00 to mount and balance them at your local stealership. Which rims do you have? The amount of time that it takes to change tires on a HUMMER depends on which rims you have and if you have runflats. What year is your truck? If you could post the size of the rim and or add a pic of them so they can be identified rims. If your truck still has the run flats on ditch them. They tend to come a bit loose over time causing your truck to shake like crazy. Also the run flats are the reason that the tires take about 8 hours to mount, without them you will GREATLY reduce the amount of time it takes to mount new tires.
