My husband recently bought a 2015 MKZ AWD with 19" aluminum wheels. I drove his car last night and could not believe how awful it was on ice. I looked into getting him snow tires, but they are way more expensive than the ones I bought for my van. It seems cheaper and maybe (?) better to buy 18" wheels and snow tires. I'm really confused about a few things:
1. Do I need to buy OEM wheels or can I just buy some cheaper ones from Tire Rack or another site?
2. I'm assuming it won't change the brakes, suspension etc to have 18" instead of 19"?
3. Do I need tire pressure sensors?
4. Am I missing anything?
Any advice would be greatly appreciated.
