I only had a test drive in a 2010 135 and never drove past 50mph in that. It only lasted about 10 minutes on good, smooth roads so I can't really compare the tires. I like the tires I have though, plenty of grip, smooth ride (and Hawaii's roads suck.)

I hear a lot of horror stories about the previous run flats and everyone who knew I was ordering a 135 told me "replace the runflats right away!" so I was surprised to find out they're not too bad at all.
