Tires OEM BMW or OEM Porsche

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

I drive my 981.2 (718) Cayman in the winter around here in Ohio and it does fine with winter tires (does better than most AWD things with just all-seasons)

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

I recently bought a ‘16 with 6,500 miles. Most everything checked out but the tires were original and dry rotted to hell.

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