What do you have your "auto lowering air suspension" set to and why on what size of the wheels? I have regular stock 20" wheels that comes with 90D in California with Continental CrossSport LX M+S tires. I just had my first MX 90D VIN 0017xx exchanged for MX 90D VIN 0415xx so nearly 40k difference in VIN and as this new car has new tires and all I was wondering what is your setting on autolowering suspension and how does it affect wear and tear on tires? I used to have my 1 year old car set to never lower and used to drive always on "standard".... I made on my tires (same ones as I have now on a new car) 49k miles in 1 year. Front tires showed at the end significant wear and tear and they looked like they need to be changed in next 3-5k miles for sure. Rear tires looked like a bit over half way done so I would say they could last another 20-30k or a bit more to my eye. Worth to mention that about 5-7k miles out of total mileage was with towing trailer 3-4k lbs. Let's get back to my question: I noticed on a new car that we took delivery 2 days ago default settings on autolowering suspension was set to "always"... I slid the slider for now to 75+ but I am just wondering if anyone has already any knowledge or experience with driving on low vs driving on standard and how does it affect wear and tear... and please also post how does it affect range, but for me this part is secondary unless there is huge difference on range Anyone any input? I tried to ask delivery specialists at Fremont but they were not really knowledgeable about this part. I may ask some tech at service center when I visit them first time to take care of something next week Any and all input really appreciated.
