Bridgestone Potenza RE050A Run Flat 235/30 R17 BMW 135i 12,000 miles August 16, 2019
I got Re050s only on the rear of my BMW 135i as they were the only Runflat tyres available.
Despite always being properly inflated and driven quietly they were harsh and have only lasted 18 months and around 20,000 km before failing a vehicle check. Very disappointing.
I'm replacing them with the OEM Dunlops.
