I awoke to an inch of snow this morning that's motivated me to line up new winter tires:

1. Cabriolet 4matic with 19" wheels (staggered; F 225/40 R 245/35). I'd like to find "econo" winter wheels and am considering whether to get 18s. Width? Offset? Never bought aftermarket wheels before and would appreciate suggestions.
2. The Cab on 19s has less than 4" clearance and I'm a little concerned about ice damage to the front spoiler beneath the bumper. Has anyone in snow country experienced this? Can I pick up a little clearance with higher profile tire
3. I'd default to Nokian Hakka studded tires because my home is on a hill and has a short but steep driveway but I've read that new rubber compounds for studless winter tires that are pretty good on ice/packed snow and wondered if anyone has tried them.

Tirerack is where I just picked up Pirelli Sotozero 3 RF. You can also get econo wheels there. Just plug in your vehicles year and other specifics and you should get a decent amount of choices. I was able to get an $80 Prepaid Visa with the Pirelli purchase last month.

Like @GreekUPS I took advantage of the TireRack sale for those Pirelli winters. Had them on my 3 series BMW and had great snow traction. Went with 18" square set-up for my 2020 C300.

TireRack will give you all the alternate sizes you can use on your vehicle. Going to 18" will give you a taller sidewall which is good for the winter, but overall ride height will not increase because total wheel diameter is unchanged.
