This will only be the 2nd time for new tires on my fiver. Its kept on a driveway at home so I just lift the tires off the ground with the Big Foot and remove the tires and take them wherever. I don't mind doing it this way compared to hitching up and driving into town.
I have never used Discount Tire but once for a car tire and they seemed very customer service driven. I have not inquired as of yet if they will mount the new 17.5 tires and as to whether they have high pressure metal valve stems. The stems that came on the rig are bit longer than I prefer especially with the TST monitor.
