Hello,

My 2011 E91 is the 320D Efficient Dynamics version. meaning I must use 205/55/16 tires.

I chose non run flat tyres, because they are more comfortable, and many roads around here are a mess.

I feel the car somewhat unstable at around 130km/h. I lowered pressure down to 2.2 in all 4 tires. It's better but not perfect.

It's worse in a straight line win windy conditions.

Any ideas? Thanks
