Do not put 225/65/15 on !!!! wrong size
Do not put 225/65/15 tires on. This is the wrong size. Read your manual. It should show that the 225/60/15 tire is an optional size for the 525i. At least my manual states this.
I put the Bridgestone Turanza 225/60/15 tires on my 525i (replaced 205/65/15 tires) about 16,000 miles ago. No problems, smooth, quiet and extremely good in the rain and no issues this winter in ice and snow. I also have traction control. I commute each day in this car. However, there as not Performace tires, they are all season tires.
