Charlotte Mobile Diesel lines up mobile semi truck tire service along with roadside diesel repair, trailer repair, air brake repair and fleet PM so a blown tire near Charlotte gets handled where it happened.
Tires are the most expensive consumable on a tractor-trailer after fuel, and a blowout is one of the most common reasons trucks end up on the shoulder. Summer heat on Charlotte's concrete interstates and the debris that collects around ongoing I-77 and I-485 construction don't help.

Services
Roadside tire replacement
Changing a blown tire on the shoulder, including dismount and mount on the wheel, and checking the mate in a dual set — a dual that ran flat often has internal damage too.
Yard tire service
Scheduled replacement, rotation, pressure audits and tread depth checks for fleets.
Wheel-end checks
Inspection of studs, nuts, hub-piloted wheel faces and hubcap oil levels while the wheel is off.
Rules of thumb that matter
- Minimum tread: 4/32 inch on steers, 2/32 inch everywhere else
- Duals should be matched within about ¼ inch in diameter
- Inflate in a safety cage or with a clip-on chuck and remote gauge after mounting
- Re-torque hub-piloted wheel nuts after the first 50–100 miles
Mounting process
- Set the parking brake, chock wheels and position the jack on a rated point.
- Deflate fully before removing a damaged tire.
- Inspect the rim for cracks and bead-seat corrosion.
- Mount, seat beads in a cage, and torque nuts in a star pattern to spec (commonly 450–500 ft-lb for hub-piloted wheels).
Casings, retreads and tire life
A well-kept casing can be retreaded more than once, which is why fleets care about casing condition at removal. Under-inflation is the biggest killer of tread life and casings; check cold pressures weekly. Retreads are legal on drive and trailer positions but not on the steer axle of buses, and most fleets keep steers on new tires.
