Hankook Ventus S1 evo3 vs Hankook Ventus ST RH06 — Compared

“That would tally with what this person found with the 127 variant that preceded it “Hi just for information,I asked Hankook what tread depth when new was on their Ventus S1 Evo 3 K127 tyre, the reply was 6.6 mm””

“You will love the Ventus S1 EVO3's, I purchased a set back in May 2020 for $473 delivered. In your climate driving at Texas speeds (75-85) efficiency is gonna be about 270-295 Wh/m. I just ordered a set of the iON EVO AS to try out as I have a need for snow use but not bad enough for snow tires.”

“For BMW-approved run flat tires, you should see a symbol that has the letters "RSC" in a circle next to the star symbol. (The "RSC" stands for "Run-flat System Component".) I don't see that symbol on the tire pictured, so it isn't a run flat. Hankook's model number for non-run flat S1 evo 3 tires is K127 whereas the run flat variant is K127B, sometimes referred to as the "SUV version". I only know this because of my quest earlier this year for efficient (yet still sporty) 225/45 R17 summer tires for my aftermarket wheels. In this size, the run flat variant actually has a better rating (B) for rolling resistance than the non-run flat (C) per the Euro tyre labels. This is a rare exception, as run flats are usually less efficient. Note that the non-run flat 205/45 R17 S1 evo 3 has an A rating, which is the most efficient. I haven't seen Euro tyre labels for the run flat variant in that size, but it seems unlikely to me they would have an A rating. As such, I would be surprised if MINI installed them at the factory due to the impact to range--unless they had no other option available due to supply chain constraints.”
