How do Run-Flat Tires Work?


“For most having a flat tire can be their
worst nightmare, especially if they are caught on the road when it happens. Being prepared
and knowing exactly what you’ve got when shopping for a car is going to be important.
Don’t be afraid to ask the dealer, what comes with the car? How does it work?” In an effort to increase fuel economy, decrease
vehicle weight and give you more trunk space, manufactures are saying so long to the spare
tire. Many new models are now equipped with inflator and sealant kits or run flat tires
which are designed to go at slower speeds for 50 miles or more after a tire has been
punctured.? “Standard low tire cannot withstand zero
pressure. It has to have pressure to keep the tire inflated. A run flat tire does not
need any pressure for a short duration of time until you can get to a shop that repairs
or replaces it.” Landon Toll used to drive a car with run flat
tires. “I had the car for about three years and
drove with 32,000 miles about and in that time I replaced the rear tires twice and the
front tires once. In total, the three years I had the car I spent a little over $2,300
just in tires alone.” In addition to being more expensive, experts
say run flats also result in a harder ride. Standard low tire will run nice and quiet
and a run flat tire will run a little bit stiff. It just depends on what kind of ride
you are looking for.” “The ride was definitely stiffer with the
run flat tires. Every bump that you would hit you would feel a little bit more.” Experts tell Angie’s List some run flat
tires can be repaired if punctured – while others cannot. It depends on the manufacturer.
