Nowadays, a number of vehicles (especially the newer ones) use run flat tires instead of the conventional ones. For instance, the BMW645ci is one specific model that runs on RFT. When the time comes around that the tires need to be replaced, the question (for some drivers) might be, ‘is it okay to replace run flat tires with conventional tires?’
The Difference between RFTs and Conventional Tires
One very noticeable difference between vehicles running on RFTs versus vehicles running on conventional tires is the absence of a spare tire. A BMW for instance, does not have a spare tire because it has RFTs on it. On the other hand, a vehicle that runs on conventional tires always has to have a spare tire with it. Run flat tires were created for the purpose of being driven on despite being un-inflated or during emergencies when there is no time for stopping and changing tires. When conventional tires are driven flat, these will quickly be worn down and shredded to pieces.
