2004 330xi M sport package

[docbenjy]

Will be upgrading to 18" wheels, probably BBS R.X.
Looking at Kumho SPT vs Proxes (4, T1-R) vs Pirelli (Zero Neros or Rossos)
Are Kumhos good trade-off price vs quality?
Mostly driving to and from work, 30 Miles/day, 20 miles highway, about 12,000 miles/year.

Thanks,

Benjamin
