Tires OEM BMW or PHANTOM

For better handling and winter traction, I would consider getting wider tires.

HD thrust arms are an improvement without too much sacrifice. Better shocks as well. I’ve found tires make a huge difference with the E39.

Narrow, low-profile tires aren't as forgiving over potholes, especially when riding on the 20" wheels.

+1 used those on my e90 BMW last year during the 'record' snowfall and the were great.

Just be warned I bought new and we don’t drive it wild or anything but both rear tires (non staggered 21”) were at 3mm tread after 10k miles and I had to replace them. Was shocking.

Phantoms are America's/Discount Tire own brand tire. They're a mid range tire that are for SUV's mainly but the smaller trucks like f-150, and the 1500's can run it if they are older from when they had the smaller frames. Better than the cheapest option out there, but don't expect top tier performance like, Michelin, Yokohama, and so on.

I'd recommend them if you do in city driving mainly, but they'll still be fine on highway driving. They're fine in wet weather as well. But again they arent top tier, but a decent budget tire so you don't break the bank.

The run flat tires are terrible. They feel like they are made of concrete and the grip is very lacking.
