315/35/20 at the back and 275/40/20 in front. Quieter, softer ride and comparable handling to the runflats they are replacing. Good dry and wet tyres. Don't know anything about snow here in Johannesburg South Africa. Genuinely impressed. I could not get more than 30000km from any of the runflats. With 10000km done, there's 90% life left on the tyre. At 20000km I'm going to swop them from one side to the other to even out the tyre wear.
