My 2015 MCS came with Dunlop Maxx 205/45/17 run flats. I have decided to go with all season 215/45/17’s and narrowed it down to Goodyear eagles or Pirelli P zero all seasons. I’ll get a spare and jack for planned 2,000mile road trips. No more run flats as the car will “skip” with cornering and hit a small road crack, like on an exit.

I need all season as living in the Rocky Mountains the daytemps, especially in winter, can go from 60F to 20F in the same day and blackice is a problem in shaded areas. 30degree temp swings are a daily occurrence. Summer temps hit over 95 with road temps extreme due to sun/altitude.

In the 90’s I had Pirellis on my Porsche and had problems with them “wearing “out of round”. Couldhave had them shaved but just replaced them. I had Goodyear eagles on my wife’s 2003 Mini and they were great. She has Hankooks on her 2013 Coupe and theyare OK, not great.

The tires are Pirelli P Zero All Season Plus and Goodyear EagleF1 Asymmetric All Season. Any reviews/experiencewould be appreciated to help me decide.

 

I've had the Goodyear Eagle F1 Asymmetric on a 2008 Volvo XC90 V8, a 2007 Volvo S80 3.2 FWD and a 2008 BMW 335xi and loved them on all 3 cars. Have nothing but good things to saw about them. Will be getting them on my 04 JCW early next year when it needs new tires

The Pirelli P Zero All Season plus looks like a good choice for you.

Comes in the original ($95 closeout) and newer revised compound ($118)
