After five years and 41,000 km, my 1 series finally suffered a flat tire, as indicated by a large red icon, and worse, its night time so no vulcanizing shop. As it has no spare tire, but equipped with Run-Flat-Tire, i had no choice but to run flat 20 km to home, thinking well, this is the time to see how RFT works.

Manufacturer says the tire is capable of running 80kph for 100 km, after which the tire would have to be replaced. Knowing an RFT could cost P15k in banawe (P30k at BMW casa!), I'm not inclined to abuse the flat tire, determined to have it vulcanized tomorrow, I drove an average 50 kph (peaked at 70kph) for the short 20km. Reached home without incident and checked the tire again. It does not look so flat after all!

Matigas pala talaga ang sidewall nito. Sana nga pwede pa mavulcanize bukas.
