What is the run-flat symbol for Pirelli?

[AshlynFitz]

Pirelli's run-flat symbols are RSC or RF. Below is relevant information on how to identify if a Pirelli tire is run-flat: Check the sidewall markings: The English term for run-flat tires is 'run-on-flat.' For example, Goodyear tires use the abbreviation ROF, Pirelli uses R-F, Bridgestone uses RFT, and there are other English markings such as Michelin's ZP (zero-pressure abbreviation), Continental's SSR, and Hankook's HRS. Based on the vehicle model: Due to the high cost of run-flat tires, a single run-flat tire is at least 300-500 RMB more expensive than a regular tire of the same model. Therefore, run-flat tires are generally only equipped on mid-to-high-end models. For example, all BMW models come standard with run-flat tires, while only some high-end Mercedes-Benz and Audi sedans are equipped with them. Based on the tire model: Generally, run-flat tires have an aspect ratio of 55 or below, and those above 60 are rare.
