Two weeks ago, I replaced my Dunlop Run Flats with Pirelli PZero 215/45/17 All Season Plus tires. Yesterday morning, I had to drive 20 miles, on country roads beforedawn. It had rained overnight and then snowed. So the roads had an ½ inch ice layer and one inch of snow covering. Temperature was 25 F.


WOW!

Could easily drive 45+ mph, safely. Never slipped once, even from deadstart. Tire Rack rated these green in all categories. Now I know why. Great tires. I'm impressed.

 

Pirelli makes the P Zero All Season and the P Zero All Season Plus (the one you got)

Very capable Ultra High Performance All Season tires that fit the MINI well. Good choice
