What is the disadvantage of a run flat tyre?
Reduced performance: Run flats may not provide the same level of performance as conventional tyres. The stiffer construction and sidewalls can affect handling and cornering capabilities, resulting in slightly compromised performance in terms of traction, braking, and overall vehicle dynamics. Run-flat tires have stiffer sidewalls that are designed to hold the wheel off the ground while you drive, even when deflated. However, rolling on a run-flat’s stiff sidewalls causes them to flex repeatedly, and they can bend only so many times before they fail completely.A run-flat tire design relies on a thicker, stiffened sidewall to carry the load in the event the tire goes low or flat. Even when properly inflated, the reinforced sidewall structure is stiffer than the sidewall of a conventional tire. The added spring rate of that stiffer sidewall can be felt over every bump.
