Title says it all. We have a 2019 M5 Competition currently running the stock Michelin sets. In our infinite wisdom, we ran off to the mountains this week as the SUV is in the shop. I’m kicking myself because of my forgetfulness and not swapping to the winter tires I already have. We’re here for 3 days and nights will be approximately 20 degrees (40-45 during the day).

Obviously, I’ll be driving like I (didn’t) steal it. Looking for some reassurance that my dumb mistake isn’t going to ruin the performance tires. It’s not the most ideal scenario.

I don’t think I’m overreacting due to the material Michelin uses in these tires going fully inelastic at cold temps. Wife thinks I’m a lunatic for worrying. On a lighter note, what’s the biggest boneheaded mistake you’ve made lately?

At 20 degrees those tires will have the grip of hockey pucks on ice. Put the car and yourself in granny mode and go slow.

The tires won’t be too bad at 45 degrees but you still have to baby those 500 + horses you’re riding.

Its xDrive, the way to go! I put down sub 3 second 0-60's in the snow on all seasons. If your afraid, granny it, but I highly doubt it will be a issue.
