According to autoweek.com BMW and MINI are the biggest embracers of runflat tires in the auto industry and the trend will continue. Tom Baloga, BMW's vice president of engineering, is quoted,It's a matter of safety as changing a tire along the side of the road is a dangerous proposition. Plus, the space where the spare tire used to be was quickly consumed in the new models for some other task. As automakers work to reduce the weights of their vehicles, eliminating the spare tire--even if it's a space-saver--helps cut curb weight.Baloga points out that runflats are better for the environment but don't perform like conventional tires.
As Matt Edmonds, vice president of the Tire Rack in South Bend, Ind. says in the article,
People are sometimes surprised about the poor ride of run-flats. It's not uncommon for people to switch from run-flats to [even] snow tires and comment that the ride is so much better.
