This is about safety and getting there, not racing.
My son is just starting a weekly commute of 50 miles each way on crooked road crossing the Sierras just north of Truckee. The elevation is all above 4,000 feet, so snowstorms and black ice will be frequent challenges.
He can put snow tires on the front of his 2002 Windstar cargo van, which has over 200K miles, but it's no doubt time for a change to a more capable car. Our 2004 Monterey minivan has Advance Trac, outside air temp, etc, which are definite improvements, but doesn't have high ground clearance.
I know 4WD cars still have only 4-wheel brakes, so I don't know if that would be worthwhile. What car and what tires would be best for this job?
