Today I changed out the Michelin StarGrip winter tires for a set of 45NRTH Gravdals. Slushy conditions today provided some motivation, because the Gravdals just barely sneak under my fenders. Today was fender weather for sure.

Got in a 13 mile ride. Rode through a mix of conditions from pavement to slush to mixed slush and ice.

The Gravdals are surprisingly decent on pavement. For a studded tire, they rolled well. They are more rounded than the StarGrips. See the second photo below.

The Gravdals did brilliantly in the packed-down slush that you see in the first photo. In fact, that photo shows my favorite surface conditions today. I enjoyed maybe three miles of those conditions.

Nearer home, the streets are a mix of loose slush a couple inches deep with occasional bits that are still sort of frozen. I got knocked around a lot in that. Not sure any other tire would have done better.

Today was 39 F. Temps will freeze overnight, and tomorrow I'll try and motivate myself to get up early and find some smooth ice. Today was really more about tread, but tomorrow the studs should come into play.
