I have 4 18" M3 wheels for sale with pirelli snow sport tires in 225 45 18 size all the way around.
Its a square set up. I bought them used and had them on last winter. Would probably also work for a regular e46 sedan/coupe.
Rims look great with only slight curb rash on one one them. About 70% tread left.
Looking for $1,000.
