Flat tires should not be driven on at all (except in emergency situations). Tires are designed to carry a load when fully inflated and when they are driven without air the sidewalls will collapse after short use. Your best solution when you do have a flat is to change to the spare tire that comes with your vehicle. Or, pull over to the side of the road and call for some kind of assistance. If you can’t change over to a spare, or don’t have a mobile phone then drive the shortest distance possible to reduce the risk of permanent damage. Tires Now can help if you need new tires.
