Run-flats are designed to give you 50 miles at 50 mph after total air loss — enough to reach a tire shop. They are not a permanent fix and they cannot be patched. Once you've driven on one flat, it needs replacement, not repair.
Driving past the run-flat distance limit destroys the tire's sidewall structure and damages the wheel. Many BMW and Mercedes owners learn this the expensive way.
Most run-flat-equipped cars do not carry a spare. If you're past the 50-mile/50-mph limit, call us for a flatbed to a tire shop. Same $249 / hour rate as every service, $224 first hour online.
