Crunch/grind noise when turning after startup
As the title says, I'm hearing a loud crunch/grind noise from the wheels when I make a 90-degree turn shortly after starting up. Once the car is fully warmed, I don't hear it any more. A friend mentioned that her Audi does the same thing. Anyone else experiencing this? Is it related to cold wheel bearings or the AWD system? Thanks all.

What kind of tires are on it? If it's summer tires, they get super hard when it's cold outside and will make clunking and what it feels like skipping feeling when they're cold and you're turning at slow speed.

This sound like what it is. Once everything warms up they stop doing it. I'll ask next time I'm at the dealer.

You are driving your summer tires in winter time. The summer is hard to begin with and the rubber compound will become even harder when temperature dips into the freezing.

Just the stock tires, but yes that sounds like what it is. I'll keep an eye on it as the weather warms up. So far they've been good in the snow, so I don't see a reason to get two sets of tires just yet, but I guess we'll see as time goes by. Thanks guys!

Summer tires in cold are very dangerous. If you ever had to do a full emergency stop or try to avoid an accident by turning hard in less than desirable conditions you'd be in a lot of trouble.

Hrm. I can't seem to find pa5s that fit the staggered setup on the 2023 E63s. And ideally I'd find a package with tires and wheels, make it easier to swap. But everything I'm seeing is in Canada (and I'm in NY). I'll keep looking. Thanks.

Beyond snow and traction, driving on summer tires below 40 degrees Fahrenheit can cause external and internal cracking and separation of the rubber because summer compounds lose their elasticity in the cold.

Assuming that's right, and I'm not debating it, seems fairly silly they'd sell these vehicles with these tires in the northeast, where we're below 40F for at least 4-5 months a year. Especially without pushing people to buy other tires. Instead they push the tire insurance package, which would seemingly lose them money if they know these tires will have issues in the cold. Either way, I'll look for another set for next winter.

I think many people aren't aware that the integrity of their summer tires can be compromised using them in cold weather.
Even with all that said, I don't see it as the end of the world, but I'd be nervous doing 100+ MPH on summer tires that were previously run at freezing temps.

Even though they are literally labeled summer tires for this reason, I totally agree this information should be much more prevalent. I'm pretty sure it's in our manuals, but nobody reads that, lol.

Yup, that's the same tire I'm running and it's a summer rated tire. Since I'm in south Florida I don't need to be concerned about swapping them myself, but if I lived somewhere where they have winter I surely would. JMO.

OP: I'm in NJ just right next to you. I really would not be comfy running on Mich Pilot Sport 4S at 40 degrees and below. I would be paranoid about hitting the brakes hard and starting to slide on a cold day, especially when it gets in the 20s. I regularly do 85 to 95 mph in the E63, CLS and the GLK when it is below freezing but I have a dedicated winter tire set up for each of the cars. The E63 runs Mich PA4s on OEM 19 inch wheels - yes the ugly winter set from MB. I do Bridgestone Blizzaks on the other two MB cars. Stay safe, hope you get a winter set that works well for you.
