What is the difference between Run Flat Tires vs Regular tires?
A Run Flat Tire can support the Weight of the Vehicle for a Short amount of Time. A Standard Tire has a soft Sidewall and will not support the Weight of the Vehicle without Air. A Run Flat Tire can do this because of its Stiffer Side Walls. Some Manufacturers will allow you to Drive on a flat for up to 100 miles. Having Run Flats on your Vehicle will give you more room in the Trunk due to not needing a Spare Tire. So remember this if you are wanting to switch from Run Flat Tires. Most Vehicles that come with Run Flats will not even have a Jack. Run Flat Tires are generally 30 to 60% more expensive than your Standard Tire. You can replace 4 Run Flat Tires with 4 Conventional Tires. You will need to make sure they meet your Vehicle's Recommendations. You cannot mix and match them. Run Flat Tires also have different Handling Characteristics. They also will not Wear as long as Conventional Tires. Some other things that may restrict you from changing to Conventional Tires. Like TPMS, Alarms and some Internal Programming may have to change.
