Hello all,
Looking for input on non-high performance tires to replace the current Michelin Pilot Sport 4S. Reason being that it gets cold in New Jersey and the current tires cannot be exposed to 20F without getting damaged/compromised.

I do not wish to go extreme all-season but want something in-between which can handle low temperatures and would permit me to drive in winter when temperatures are in 20s.
Also, the wheels are 20 inch and tires are 285/35, is it possible to use higher profile (i.e. greater than 35 or 40) tires or is the space in the wheel well inadequate? It is ok if speed rating is lower, no plan to exceed 130mph ever.

Start your search at TireRack.com and/or Consumer Reports (cr.org) or Car&Driver/MotorTrend online.
Good luck!

You can go to Michelin Pilot Sport AS 4's. The "AS" stand for all season, which are different from the regular PS4's or PS5's But my favorite are the Continental DWS-06 Plus tires. Both are available at Tirerack/Discount Tire/America's Tire.
Otherwise you can go to grand touring all season, which I don't recommend for an S63.

Appreciate the suggestions- may go with DWS-06, seems to be good value. Will purchase closer to November-December.
Any flexibility in going from 35 to 40 for rears?

Your options are limited on a performance car with low profile wheels/tires. As said, you can go with UHP all-season tires. They are still high performance tires, but designed for lower temperatures. As far as I can see the Conti DWS 06, PS AS 4 and Goodyear Eagle Exhilarate are the three options at least for the 2019. For touring tires, you need to go down in wheel size, but that will be difficult due to size of the brakes. There are very few winter tires for these kinds of cars as well.

We have been on the Contis in our cars....like them a lot. That said, the E63 will be back on Michelin next time around cause Conti discontinued their tire that fit.

Great - you essentially narrowed down the options I have and confirmed my uncertainly around going down in size. Think I will be ok with DWS-06.
Thank you.

You could potentially change your tires to taller tires, but you'd have to change all 4 to match. I haven't found a compatible setup, but you can use this tire size calculator to see if you can do it: https://www.willtheyfit.com/
You can also call Discount Tire or Tire and Rack and see what they say is possible. And just about anything is "possible" if you want to do it, but staying within spec will protect your car's cuspension components.

OP very little room in there for taller tire. It will rub fender liners in tight turns. They wear away quickly.

Can you fit a 19” wheel over the brakes? If so go that route with a tire that makes the same overall diameter as standard. Taller sidewall helpful with potholes and frost heaves.

I really enjoyed the Continental DWS-06 on the 221 S-65. They are excellent in rain and surprisingly good in snow.

Thanks for all the responses.

How do I close this thread? I wish to start another on wheel alignment - got some strange responses from service manager at M-B dealership.

You don't close threads. Only moderators can close threads if they get out of hand. Just start a new thread with a new question.
