Had the Michelin A/S 4s mounted last night, 265/285/40/21, these are the tires that should have came on the car. The stock difficulties are frustrating... No rubbing for me, we tried to mimick what others have said cause rubbing and was not able to replicate. This was with around 180lbs in driver seat, 220 in the passenger seat, and 140lbs on both sides in the rear.
The cars suspension is still firm, however the tires take away a bit of the harshness on poor roads.
For those with the Walmart issue, I ran into the same thing where they initially could not scan the tires in for return due to item not found. They were able to process it eventually after a manager came out and entered the return differently.
I ended up getting the fronts from discount tire direct, found a pair of rears on ebay, new. Good luck all. Find a solution to not run summer tires in the winter. It's dangerous, don't risk it.
