Tires OEM BMW or Shinko

I have shinko 805/804s, they are pretty identical to the 606s, and I absolutely love them. If you balance them well they ride good at 75mph, and handle dirt fantastic.

I switched to the shinko 244 front and have loved the d606 rear combo. It dives into the corners on the road and will give you about 80% confidence on the dirt.

Ran a set of 777s on my sportster and they are great tires ! Was very happy with them.

HD thrust arms are an improvement without too much sacrifice. Better shocks as well. I’ve found tires make a huge difference with the E39.

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

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

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